2.1.2.1. A "universal" category for use as specified in Paragraphs 6.1.1., 6.1.3.1., and 6.1.3.2.
on most vehicle seat positions, and in particular those which have been assessed
according to Regulation No. 16, � as being compatible with such a category of child
restraint.
2.1.2.2. A "restricted" category for use as specified in Paragraphs 6.1.1. and 6.1.3.1. in
designated seat positions for particular vehicle types as indicated by either the child
restraint manufacturer or the vehicle manufacturer:
2.1.2.3. A "semi-universal" category for use as specified in Paragraphs 6.1.1. and 6.1.3.2;
2.1.2.4. A "specific vehicle" category for use either;

2.1.2.4.2. As a "built in" child restraint.

---

2.8. "Strap" means a flexible component designed to transmit forces;
2.8.1. "Lap strap" means a strap which, either in the form of a complete belt or in the form of
a component of such a belt, passes across the front of, and restrains, directly or not,
the child's pelvis;
2.8.2. "Shoulder restraint" means that part of a belt which restrains the child's upper torso;
2.8.3. "Crotch strap" means a strap (or divided straps, where two or more pieces of webbing
make it) attached to the child restraint and the lap strap and is so positioned as to pass
between the child's thighs; it is designed to prevent the child sliding under the lap belt
in normal use and prevent the lap belt moving up off the pelvis in an impact.
2.8.4. "Child-restraining strap" means a strap which is a constituent part of the belt and
restrains only the body of the child;
2.8.5. "Child-restraint attachment strap" means a strap which attaches the child restraint to
the structure of the vehicle and may be a part of the vehicle-seat retaining device;

where fitted, a crotch strap;
2.8.7. "Y-shaped belt" means a belt where the combination of straps is formed by a strap to
be guided between the child's legs and a strap for each shoulder.
2.8.8. "Guide strap" means a strap or device which constrains the shoulder strap of the adult
seat belt in a position to suit the child and where the effective position at which the
shoulder strap changes direction can be adjusted by means of a device which can be
moved up and down the strap to locate the wearer's shoulder, and then locked into that
position. This guide strap is not meant to carry a significant part of the dynamic load. A
guide strap is considered as a part of a child restraint system and cannot be separately
approved as a child restraint system under this Regulation.
2.9. "Buckle" means a quick release device which enables the child to be held by the
restraint or the restraint by the structure of the car and can be quickly opened. The
buckle may incorporate the adjusting device;

supported by the webbing that it is designed to adjust.

---

2.14.4. "Anti-rotation device"
(a)
(b)
(c)
An anti-rotation device for an ISOFIX universal child restraint system consists of
the ISOFIX top-tether.
An anti-rotation device for an ISOFIX semi-universal child restraint system
consists of either a top tether, the vehicle dashboard or a support leg intended to
limit the rotation of the restraint during a frontal impact.
For ISOFIX, universal and semi-universal, child restraint systems the vehicle
seat itself does not constitute an anti-rotation device.
2.14.5. "ISOFIX top tether anchorage" means a feature fulfilling the requirements of
UN Regulation No. 14 or UN Regulation No. 145, such as a bar, located in a defined
zone, designed to accept an ISOFIX top tether strap connector and transfer its restraint
force to the vehicle structure.
2.15. "Forward-facing" means facing in the normal direction of travel of the vehicle.
2.16. "Rearward-facing" means facing in the direction opposite to the normal direction of
travel of the vehicle.
2.17. "Inclined position" means a special position of the chair which allows the child to
recline.

head and body excluding its limbs are on a horizontal surface when at rest in the
restraint.
2.19. "Child-restraint type" means child restraints which do not differ in such essential
respects as:
2.19.1. The category, and the mass group(s) for which and the position and orientation (as
defined in Paragraphs 2.15. and 2.16.) in which the restraint is intended to be used;
2.19.2. The geometry of the child restraint;
2.19.3. The dimensions, mass, material and colour of:
The seat;
The padding; and
The impact shield;
2.19.4. The material, weave, dimensions and colour of the straps;
2.19.5. The rigid components (buckle, attachments, etc.).

---

2.23. "Seat type" means a category of adult seats which do not differ in such essential
respects as:
2.23.1. The shape, dimensions and materials of the seat structure,
2.23.2. The types and dimensions of the seat-lock adjustment and locking systems, and
2.23.3. The type and dimensions of the adult safety-belt anchorage on the seat, of the seat
anchorage, and of the affected parts of the vehicle structure.
2.24. "Displacement system" means a device enabling the adult seat or one of its parts to
be displaced angularly or longitudinally, without a fixed intermediate position, to
facilitate the entry and exit of passengers and the loading and unloading of objects.
2.25. "Locking system" means a device ensuring that the adult seat and its parts are
maintained in the position of use.
2.26. "Lock-off device" is a device which locks and prevents movement of one section of
the webbing of an adult safety-belt relative to another section of the webbing of the
same belt. Such devices may act upon either diagonal or lap section or secure together
both lap and diagonal sections of the adult belt. The term covers the following classes:
2.26.1. "Class A device", a device that prevents the child pulling webbing from the retractor
through to the lap part of the belt, when the adult belt is used to restrain the child
directly.
2.26.2. "Class B device", a device that allows the retention of an applied tension in the lap
part of an adult safety-belt, when the adult belt is used to restrain the child restraint.
The device is intended to prevent webbing slipping from the retractor through the
device, which would release the tension and place the restraint in a non-optimal
position.
2.27. "Special Needs Restraint" is a child restraint system designed for children who have
special needs as a result of either a physical or mental handicap; this device may in
particular permit additional restraining devices for any part of the child, but it shall
contain as a minimum a primary means of restraint which complies with the
requirements of this Regulation.
2.28. "ISOFIX attachment" means one of the two connections, fulfilling the requirement of
Paragraph 6.3.2. of this Regulation, extending from the ISOFIX child restraint system
structure, and compatible with an ISOFIX low anchorage.
2.29. "ISOFIX child restraint system" means a child restraint system which has to be
attached to an ISOFIX anchorage system fulfilling the requirement of
UN Regulation No. 14 or UN Regulation No. 145.
2.30. "Seat bight" means the area close to the intersection of the surfaces of the vehicle
seat cushion and the seat back.
2.31. "Vehicle seat fixture (VSF)" means a fixture, according to ISOFIX size classes
defined in Paragraph 2.1.1.6. and whose dimension are given in Figures 1 to 6 of
Annex 17 Appendix 2 of Regulation No. 16, used by a child restraint manufacturer to
determine the appropriate dimensions of an ISOFIX child restraint system and the
location of its ISOFIX attachments.

6.2 Configuration
6.2.1. The configuration of the restraint shall be such that
6.2.1.1. The restraint gives the required protection in any intended position of the restraint
system; for "Special Needs Restraints" the primary means of restraint shall give the
required protection in any intended position of the restraint system without the use of
the additional restraining devices which may be present.
6.2.1.2. The child is easily and quickly installed and removed; in the case of a child restraint
system in which the child is restrained by means of a harness belt or a Y-shaped belt
without a retractor each shoulder restraint and lap strap shall be capable of movement
relative to each other during the procedure prescribed in Paragraph 7.2.1.4.
In these cases the belt assembly of the child restraint system may be designed with
two or more connecting parts. For "Special Needs Restraints" it is recognized that the
additional restraining devices will restrict the speed by which a child can be installed
and removed. However, the additional devices shall be designed to release quickly so
far as possible.
6.2.1.3. If it is possible to change the inclination of the restraint, this change in inclination shall
not require manual readjustment of the straps. A deliberate hand-action is required in
order to change the inclination of the restraint.
6.2.1.4. The Groups 0, 0+ and I restraint systems shall keep the child so positioned as to give
the required protection even when the child is asleep;
6.2.1.5. For all forward-facing Group I restraints incorporating an integral harness belt system to
prevent submarining, either by impact or through restlessness, a crotch strap shall be
required.

---

6.2.4. The design shall be such that compression loads shall not be imposed on the crown of
the child's head in the event of a collision.
6.2.4.1. Y-shaped belts may only be used in rearward facing and lateral facing child restraint
systems (carry-cots).
6.2.5. The child restraint shall be so designed and installed as:
6.2.5.1. To minimize the danger of injury to the child or to other occupants of the vehicle
through sharp edges or protrusions (as defined in Regulation No. 21, for example);
6.2.5.2. Not to exhibit sharp edges or protrusions liable to cause damage to vehicle-seat covers
or to occupant's clothing;
6.2.5.3. Not to subject weak parts of the child's body (abdomen, crotch, etc.) to supplementary
inertial forces it sets up;
6.2.5.4. To ensure that its rigid parts do not, at points where they are in contact with straps,
exhibit sharp edges capable of abrading the straps.
6.2.6. Any part made separable to enable components to be fixed and detached shall be so
designed as to avoid any risk of incorrect assembly and use so far as possible.
"Special Needs Restraints" may have additional restraining devices; these shall be
designed to avoid any risk of incorrect assembly and that their means of release and
mode of operation is immediately obvious to a rescuer in an emergency.
6.2.7. Where the child restraint intended for Group I, Group II and Groups I and II combined
includes a chair back, the internal height of the latter, determined in accordance with
the diagram in Annex 12, shall be not less than 500mm.
6.2.8. Only automatically-locking retractors or emergency-locking retractors may be used.
6.2.9. For devices intended for use in Group I it shall not be possible for the child to easily
slacken that part of the system that restrains the pelvis after the child has been
installed; for this purpose the requirements of Paragraph 7.2.5. (lock-off devices) shall
be fulfilled; any device that is designed to obtain this shall be permanently attached to
the child restraint system.
6.2.10. A child restraint may be designed for use in more than one mass group and/or by more
than one child, provided that it is able to satisfy the requirements laid down for each of
the groups concerned. A child restraint in the "universal" category shall meet the
requirements of that category for all mass groups for which it has been approved.
6.2.11. Child Restraints with Retractor
In the case of a child restraint incorporating a retractor, the retractor shall have met the
requirements of Paragraph 7.2.3. below.
6.2.12. In case of booster cushions, the ease with which the straps and tongue of an adult belt
pass through the fixture points shall be examined. This goes particularly for booster
cushions which are designed for the front seats of cars, which may have long semi-rigid
stalks. The fixed buckle should not be allowed to pass through the fixture points of
booster seats, or to permit a lie of belt completely different from that of the test-trolley.

Paragraph 8.1.3. below.
7.1.4.1.1. Child restraints of the "universal", "restricted" and "semi-universal" categories shall be
tested on the test trolley by means of the test seat prescribed in Paragraph 6., and in
conformity with Paragraph 8.1.3.1.
7.1.4.1.2. Child restraints of the "specific vehicle" category shall be tested with each vehicle
model for which the child restraint is intended. The Technical Service responsible for
conducting the test may reduce the number of vehicle models tested if they do not
differ greatly in the aspects listed in Paragraph 7.1.4.1.2.3. The child restraint may be
tested in one of the following ways:
7.1.4.1.2.1. On a complete vehicle, as prescribed in Paragraph 8.1.3.3.;
7.1.4.1.2.2. In a vehicle body shell on the test trolley, as prescribed in Paragraph 8.1.3.2.; or,
7.1.4.1.2.3. In sufficient parts of the vehicle bodyshell to be representative of the vehicle structure
and impact surfaces. If the child restraint is intended for use in the rear seat, these shall
include the back of the front seat, the rear seat, the floor pan, the B and C pillars and
the roof. If the child restraint is intended for use in the front seat, the parts shall include
the dashboard, the A pillars, the windscreen, any levers or knobs installed in the floor
or on a console, the front seat, the floor pan and the roof. Furthermore, if the child
restraint is intended for use in combination with the adult safety belt, the parts shall
include the appropriate adult belt(s). The Technical Service responsible for conducting
the test may permit items to be excluded if they are found to be superfluous. Testing
shall be as prescribed in Paragraph 8.1.3.2.
7.1.4.1.3. The dynamic test shall be performed on child restraints which have not previously been
under load.
7.1.4.1.4. During the dynamic tests, no part of the child restraint actually helping to keep the child
in position shall break, and no buckles or locking system or displacement system or
support leg shall break or release or collapse, except where identified as a load limiting
device. Any load limiting device shall be clearly identified in the manufacturer's
technical descriptions as defined in Paragraph 3.2.1. of this Regulation.
7.1.4.1.5. In the case of "non-integral type" the seat belt used shall be the standard belt and its
anchorage brackets prescribed in Annex 13 to this Regulation. This does not apply to
"specific vehicle" approvals where the actual belt of the vehicle shall be used.
7.1.4.1.6. If a "specific vehicle" child restraint system is installed in the area behind the rearmost
forward facing adult seat positions (for example, the luggage area), one test with the
largest dummy/dummies on a complete vehicle as prescribed in Paragraph 8.1.3.3.3.
shall be performed. The other tests, including the conformity of production, may be
done as prescribed in Paragraph 8.1.3.2., if the manufacturer so wishes.
7.1.4.1.7. In the case of a "Special Needs Restraint" every dynamic test specified by this
Regulation for each mass group shall be performed twice: first, using the primary
means of restraint and second, with all restraining devices in use. In these tests,
special attention shall be given to the requirements in Paragraphs 6.2.3. and 6.2.4.

8.2.1.3.1 For the strength test two samples have to be used. All adjusters, except for adjusters
mounted directly on a child restraint are included in the test.
8.2.1.3.2. Annex 20 shows a typical device for a buckle strength test. The buckle is placed on the
upper round Plate (A) within the relief. All adjacent straps have a length of at least
250mm and are arranged hanging down from the upper plate respective to their
position at the buckle. The free strap ends are then wound round the lower round
Plate (B) until they come out at the plate's inner opening. All straps have to be vertical
between A and B. The round clamping Plate (C) is then lightly clamped against the
lower face of (B), still allowing a certain strap movement between them. With a small
force at the tensile machine the straps are tensioned and pulled between (B) and (C)
until all straps are loaded respective to their arrangement. The buckle shall stay free
from Plate (A) or any parts at (A) during this operation and the test itself. (B) and (C)
are then clamped firmly together and the tensile force is increased at a traverse speed
of 100 ± 20mm/min until the required values are reached.

8.2.5.2.6.2. The Table below sets out the general conditions for each test:
Load (N) Cycles per minute Cycles (No.)
Type 1 procedure 60 ± 0.5 30 ± 10 1,000 ± 5
Type 2 procedure 10 ± 0.1 30 ± 10 5,000 ± 5
8.2.5.2.6.3. Particular Test Conditions
8.2.5.2.6.3.1. Type 1 Procedure:
For cases where the strap slides through the quick adjusting device. Apply a load of
10N, if necessary the load may be increased by 10N steps so as to permit correct
sliding, but limited to a maximum of 60N. This load shall be vertically and permanently
applied on the straps. The part of the strap set horizontally shall pass through the quick
adjuster it is fitted to and shall be attached to a device, giving the webbing a back and
forth motion. The quick adjusting device shall be so placed that the horizontal strap of
the webbing remains under tension (see Annex 5, Figure 1). Activate the quick adjuster
while pulling the straps in the direction to slacken the harness and deactivate it while
pulling the straps in the direction to tighten the harness.
8.2.5.2.6.3.2. Type 2 Procedure:
For cases where the strap changes direction in passing through a rigid part. During this
test, the webbing shall pass through the rigid part it is intended for and the test set up
shall reproduce the angles as in the real installation (in three dimensions), see
Annex 5, Figure 2 for examples. The 10N load shall be permanently applied. For cases
where the strap changes direction more than once in passing through a rigid part, the
load of 10N may be increased by 10N steps so as to permit correct sliding and achieve
the prescribed 300mm of strap movement through that rigid part.

Paragraph 7.1.3.1.
Stopping of the rig during the overturning is not allowed.
Paragraph 7.1.4.1.4.
The Paragraph aims to ensure that the CRS will sustain all imposed loads during the dynamic test,
keeping the child in position, by maintaining the original position and configuration. Any change in the
original configuration, including change in the reclining position or in the support leg length shall be
considered a failure. Any load bearing part or component failure, like adult safety belt contact points
(identified as a belt route), anti-rotation device or CRS chair shell shall be considered a failure, except
where such behaviour is clearly identified as load limiting device function.
Paragraph 7.1.4.1.10.1.2.
Completely recessed means that with the leg in the stowed position, no part of the leg protrudes beyond
the surface of the base or shell, such that it has no effect on the position of the CRS on the test bench.
See the following figures for clarification examples.

Paragraph 8.2.2.1.1.
"Having regard to normal conditions of use" means that this test should be performed with the restraint
mounted on the test or vehicle seat but without the dummy.
The dummy shall be used only to position the adjusting device. In the first instance the straps should be
adjusted in accordance with Paragraphs 8.1.3.6.3.2. or 8.1.3.6.3.3. (whichever is appropriate). The test
should then be conducted after removal of the dummy.
Paragraph 8.2.5.2.6.
This Paragraph shall not apply to guide straps which are approved separately under this Regulation.
Paragraph 10.1.3.
10.1.3. In the case of extensions where the modifications affect only one CRS group, perform
extension test only for that group, and if the excursion result is worse than for the previous
worst case for the CRS (from any group from the original approval or previous extensions)
then conduct new production qualification tests. If the head excursion is no worse than any
other previous approval or extension testing (excluding PQ tests) further production
qualification testing is not required.
In cases where the extension modifications affect more than one group, for example if
extending a Group 2/3 CRS to add Group 1, but the modification can affect Group 2/3
(e.g.: strengthening), than perform Group 1 tests and the worst case Group 2/3 (original
approval). If any result is worse than the original approval or previous extension (excluding
PQ tests) then perform production qualification tests on the new worst case.
Always compare to the worst case from all approval and extension testing (excluding any
PQ tests).

2. TEST FREQUENCY AND RESULTS
2.1. The frequency of testing to the requirements of Paragraphs 1.1. to 1.5. and 1.7. shall be on a
statistically controlled and random basis in accordance with one of the regular quality
assurance procedure, and shall be conducted at least once per year.
2.2. Minimum conditions for the control of conformity of child restraint systems of categories
"Universal", "Semi Universal" and "Restricted", in relation to the dynamic tests according to
Paragraph 1.6.
In accordance with the relevant authorities, the holder of an approval will supervise the control
of conformity following the method of batch control (Paragraph 2.2.1.) or following the method
of continuous control (Paragraph 2.2.2.).
2.2.1. Batch Control for the Child Restraint Systems
2.2.1.1. The holder of an approval shall divide the child restraint systems into batches which are as
uniform as possible in regard to raw material or intermediate products involved in their
manufacture (different colour of shell, different manufacture of harness) and in regard to
production conditions. The numbers in a batch shall not exceed 5,000 units.
In agreement with the relevant authorities the tests can be carried out by the Technical
Service authorities or under the responsibility of the holder of an approval.
2.2.1.2. A sample shall be taken in each batch in accordance with the provisions of Paragraph 2.2.1.4.
from a minimum of 20% of the batch quantity, which has to be produced of the actual batch.
2.2.1.3. The characteristics of the child restraint systems and the number of dynamic tests to be
conducted are given in Paragraph 2.2.1.4.

2.2.2. Continuous Control
2.2.2.1. The holder of an approval shall be obliged to carry out continuous quality control of his
manufacturing process on a statistical basis and by sampling. In agreement with the relevant
authorities, the tests can be carried out by the Technical Service authorities or under the
responsibility of the holder of an approval which is responsible for the traceability of the
product.
2.2.2.2. The samples shall be taken in accordance with the provisions of Paragraph 2.2.2.4.
2.2.2.3. The characteristic of the child restraint systems is taken at random and the tests to be carried
out are described in Paragraph 2.2.2.4.
2.2.2.4. Control shall meet the following requirements.
Child restraint systems taken
0.02% means one child restraint system taken from every
5,000 manufactured
0.05% means one child restraint system taken from every
2,000 manufactured
Degree of control rigour
Normal
Strengthened
This dual sampling plan functions as follows:
If the child restraint system is considered to conform, the production conforms.
If the child restraint system does not meet the requirements, a second child restraint system
shall be taken,
If the second child restraint system meet the requirements, the production conforms,
If both (the first and the second) child restraint systems do not meet the requirements, the
production does not conform and child restraint systems that are likely to present the same
failure shall be withdrawn and necessary steps shall be taken to re-establish the conformity of
the production.
Strengthened control will replace normal control if, out of 10,000 child restraint systems
manufactured consecutively, the production has to be withdrawn twice.
Normal control is resumed if 10,000 child restraint systems manufactured consecutively are
considered to conform.
If production subjected to the strengthened control has been withdrawn on two consecutive
occasions, the provisions of Paragraph 13. are applied.
2.2.2.5. The continuous control of child restraint systems is undertaken starting after the production
qualification.
2.2.2.6. The test results described in Paragraph 2.2.2.4. shall not exceed L, where L is the limit value
prescribed for each approval test.

the reference belt at the outboard position to achieve a load of 75N ± 5N at the outboard
position.
1.2. Lap and Diagonal Belt
1.2.1. Fit load cell 1 to the outboard position as shown above. Install the child restraint into the correct
position. If a lock-off device is fitted to the child restraint and acts upon the diagonal belt, place
load cell 2 at a convenient position behind the child restraint between the lock-off device and
the buckle as shown above. If no lock-off device is fitted or if the lock-off device is fitted at the
buckle, position load cell at a convenient position between the pillar loop and the child restraint.

NOTE
1. Installation is conducted after fitting the manikin into the restraint, for Paragraphs 1.1. and 1.2.
2. Because the foam test cushion will compress after installation of the child restraint, the dynamic
test shall be conducted no more than 10min after installation as possible. To allow the cushion to
recover, the minimum period between two tests using the same cushion shall be 20min.
3. Load cells fitted directly onto the belt webbing may be disconnected electrically, but shall be left
in place during the dynamic test. The mass of each cell is not to exceed 250g. Alternatively the
lap belt webbing load cell may be replaced by a load cell fixed at the anchorage point.
4. In the case of restraints fitted with devices intended to increase the adult safety-belt tension, the
test method shall be:
Install the child restraint system as required in this Annex and then apply the tensioner device as
stated in the manufacturers instructions. If the device cannot be applied due to excess tension
then it is deemed to be an unacceptable device.
5. No additional force shall be applied to the child restraint system other than the minimum required
to achieve the correct installation forces as specified in Paragraphs 1.1. and 1.2.2.
6. In case of carry-cot installed as described in Paragraph 8.1.3.5.6., the connection between the
adult safety belt and the restraint shall be simulated. A 500mm free end length adult safety belt
(measured as described in Annex 13) is connected by the anchoring plate described in Annex 13
to the prescribed anchoring points. The restraint is then connected to the free end adult safety
belts. The tension on the adult safety belt, measured between the anchoring point and the
restraint shall be 50 ± 5N.

ANNEX 24
FLAMMABILITY OF MATERIALS INTENDED TO BE USED IN BUILT-IN
CHILD RESTRAINT SYSTEMS
1. DEFINITIONS
"Occupant compartment air space" means the space within the occupant compartment that
normally contains refreshable air.
2. MATERIAL SELECTION (see Figure 1 below)
2.1. Any portion of a single or composite material which is within 13mm of the occupant
compartment air space shall meet the requirements in Paragraph 6.1.6.
2.1.1. Any material that does not adhere to other material(s) at every point of contact shall meet the
requirements of Paragraph 6.1.6.when tested separately
2.1.2. Any material that adheres to other materials at every point of contact shall meet the
requirements of Paragraph 6.1.6. when tested as a composite with the other material(s).
Material A has a non-adhering interface with Material B and is tested separately.
Part of Material B is within 13mm of the occupant compartment air space, and Materials B
and C adhere at every point of contact; therefore, B and C are tested as a composite.
The cut is in Material C as shown in Figure 1, to make a specimen 13mm thick
3. TEST PROCEDURE
Figure 1
3.1. The test is conducted in a metal cabinet for protecting the test specimens from drafts. The
interior of the cabinet is 381mm long, 203mm deep, and 356mm high. It has a glass
observation window in the front, a closable opening to permit insertion of the specimen holder,
and a hole to accommodate tubing for a gas burner. For ventilation, it has a 13mm clearance
space around the top of the cabinet, ten holes in the base of the cabinet, each hole 19mm in
diameter and legs to elevate the bottom of the cabinet by 10mm, all located as shown in
Figure 2.

---

5.2. Place the mounted specimen in a horizontal position, in the centre of the cabinet.
5.3. With the flame adjusted according to 2.4, position the bunsen burner and specimen so that the
centre of the burner tip is 19mm below the centre of the bottom edge of the open end of the
specimen.
5.4. Expose the specimen to the flame for 15s.
5.5. Begin timing (without reference to the period of application of the burner flame) when the flame
from the burning specimen reaches a point 38mm from the open end of the specimen.
5.6. Measure the time that it takes the flame to progress to a point 38mm from the clamped end of
the specimen. If the flame does not reach the specified end point, time its progress to the point
where flaming stops.
5.7. Calculate the burn rate from the formula:
B = 60 × (D/T)
Where:
B = Burn rate in millimeters per minute
D = Length the flame travels in millimeters, and
T = Time in seconds for the flame to travel D millimeters.
