2.1.2. Child restraints fall into four "categories":
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;
2.1.2.4.1. On specific vehicle types, in accordance with Paragraphs 6.1.2. and 6.1.3.3.; or
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;
2.8.6. "Harness belt" means a belt assembly comprising a lap belt, shoulder restraints and,
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;
2.9.1. "Enclosed buckle release button", a buckle release button such that it shall not be
possible to release the buckle using a sphere having a diameter of 40mm;
2.9.2. "Non-enclosed buckle release button", a buckle release button such that it shall be
possible to release the buckle using a sphere having a diameter of 40mm.
2.10. "Adjusting device" means a device enabling the restraint or its attachments to be
adjusted to the physique of the wearer, the configuration of the vehicle, or both. The
adjusting device may either be part of the buckle or be a retractor or any other part of
the safety belt;
2.10.1. "Quick adjuster" means an adjusting device which can be operated by one hand in
one smooth movement.
2.10.2. "Adjuster mounted directly on child restraint" means an adjuster for the integral
harness which is directly mounted on the child restraint, as opposed to being directly
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
Regulation No. 14, 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.
2.18. "Lying down/supine/prone position" means a position where at least the child's
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
Regulation No. 14.
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.

POSSIBLE CONFIGURATIONS FOR APPROVAL
GROUPS / CATEGORIES TABLE

6.1.4. A booster cushion shall be restrained by either an adult belt, using the test as specified
in Paragraph 8.1.4., or by separate means.
6.1.5. The Child Restraint System manufacturer shall declare in writing that the toxicity of
materials used in the manufacture of restraint systems and accessible to the restrained
child is in conformity with the relevant parts of EN 71-3:2013+A1:2014 (Paragraph 4.2.,
Table 2, Category III for specific requirements and Paragraph 7.3.3. for test
methodology). Tests confirming the validity of the declaration may be carried out at the
discretion of the Technical Service. This paragraph does not apply to restraint devices
of Groups II and III.
6.1.6. The flammability of Child Restraint Systems submitted for approval shall be assessed
by one of the following methods:
Method 1 is applicable only to non-built-in Child Restraint Systems and Method 2 is
applicable only to vehicle specific built-in Child Restraint Systems.
Method 1
The Child Restraint System manufacturer shall declare in writing that the flammability
of materials used to manufacture the Child Restraint System is in conformity with the
method of Section 5.4 of EN 71-2:2011+A1:2014 with a maximum rate of spread of
flame of 30mm/s. Tests confirming the validity of the declaration may be carried out at
the discretion of the Technical Service. Where fabrics are assembled together, these
shall be tested as a composite.
"Composite material" means a material composed of several layers of similar or
different materials intimately held together at their surfaces by cementing, bonding,
cladding, welding, etc. In such a case, the material shall be tested as a composite.
When different materials are connected together intermittently, such materials shall not
be considered as composite materials and therefore tested separately.
Tests confirming the validity of the declaration may be carried out at the discretion of
the Technical Service.
Method 2
The applicant shall declare in writing that when testing materials in accordance with
Annex 24 of this regulation, the materials used shall not burn, nor transmit a flame front
across its surface, at a rate of more than 100mm per minute. Each material used in a
child restraint system shall conform to these requirements. However, the requirement
concerning transmission of a flame front shall not apply to a surface created by cutting
a test specimen for purposes of testing pursuant to Annex 24.
The requirements shall be met in both the "in-use" and in the "stowed" positions of the
built-in Child Restraint System.
If a material stops burning before it has burned for 60s from the start of timing, and has
not burned more than 51mm from the point where the timing was started, it shall be
considered to meet the burn-rate requirement specified above.
Tests confirming the validity of the declaration may be carried out at the discretion of
the Technical Service.

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.
6.2.2. For Groups I, II and III, all restraint devices utilizing a "lap strap" shall positively guide
the "lap strap" to ensure that the loads transmitted by the "lap strap" are transmitted
through the pelvis. The assembly shall not subject weak parts of the child's body
(abdomen, crotch, etc.) to excessive stresses.
6.2.2.1. With the crotch strap attached and in its longest position if adjustable, it shall not be
possible to adjust the lap strap to lie above the pelvis of both the smallest and largest
dummy within the mass groups covered by the approval. For all forward-facing
restraints, it shall not be possible to adjust the lap strap to lie above the pelvis of both
the smallest and largest dummy within the mass groups covered by the approval.
6.2.2.2. During the dynamic test, as prescribed in Paragraph 8.1.3., the lap belt shall not pass
fully beyond the pelvic structure of the dummy, during the period prior to maximum
horizontal head excursion. Assessment shall be carried out using high speed video
imaging.
6.2.3. All straps of the restraint shall be so placed that they cannot cause discomfort to the
wearer in normal use or assume a dangerous configuration. The distance between the
shoulder-straps in the vicinity of the neck should be at least the width of the neck of the
appropriate manikin.

6.2.13. If the child restraint is designed for more than one child, each restraint system shall be
fully independent with regard to load transfer and adjustments.
6.2.14. The child restraints incorporating inflatable elements shall be so designed that the
conditions of use (pressure, temperature, humidity) have no influence on their ability to
comply with the requirements of this Regulation.

rearward impact shall be conducted with the worst case position selected by the
Technical Service. During the tests the support leg shall be supported by the
trolley floor pan as described in Annex 6, Appendix 3, Figure 2. If there is
clearance between the shortest leg length and the highest floor pan level, the leg
is adjusted to the floor pan level of 140mm below Cr. If the maximum leg length
is more than the lowest floor pan level would allow to be used, the leg is adjusted
to that lowest floor pan level of 280mm below Cr. In the case of support leg with
adjustable steps, the support leg length shall be adjusted to the next adjustment
position, in order to ensure the support leg is in contact with the floor.
b) In the case of support legs out of the plane of symmetry, the worst case shall be
selected by the Technical Service for the test.
c) In the case of specific vehicle category, the support leg shall be adjusted as
specified by the child restraint manufacturer.
7.1.4.1.10. In the case of a child restraint making use of an ISOFIX anchorage system and

can be completely recessed within the base or the shell of the CRS, the test is
conducted with the device in its stowed position or with the leg removed respectively. If
it cannot be completely recessed within the base, the test is performed with the device
deployed in its shortest length with the trolley floor pan in its lowest position.
This requirement does not apply when a permanent and non-adjustable support leg is
used as an anti-rotation device.
7.1.4.1.10.2. For ISOFIX child restraint system of other size classes with the anti-rotation device in
use.

ANNEX 15
EXPLANATORY NOTES
The explanatory notes given in this Annex concern interpretation difficulties with the Regulation. They are
meant as a guide for the Technical Services performing the tests.
Paragraph 2.10.1.
A quick adjuster can also be a device with a rotation shaft and spring similar to a retractor with a manual
release. The adjuster should be tested to the requirements of Paragraphs 7.2.2.5. and 7.2.3.1.3.
Paragraph 2.19.2.
A semi-universal restraint specified for fitting to the rear seat in both a saloon and an estate type vehicle
in which the whole belt assembly is identical is one "type".
Paragraph 2.19.3.
The significance of changes in the dimensions and/or mass of the seat, padding or impact shield and the
energy-absorbing characteristics or colour of the material are to be considered when deciding whether a
new type has been created.
Paragraphs 2.19.4. and 2.19.5.
These Paragraphs shall not apply to any safety belts separately approved in accordance with
Regulation No. 16 which is necessary to anchor the child restraint to the vehicle or to restrain the child.
Paragraph 6.1.2.
For rearward-facing child restraints the correct position of the top of the restraint relative to the child
dummy head is ensured by installing the largest dummy, for which the device was specified, in the most
reclined configuration, and making sure that a horizontal line at the eye height passes below the top of
the seat.
Paragraph 6.1.8.
The 150mm requirement also applies to carry-cots.
Paragraph 6.2.4.
The limit of acceptable movement of the shoulder belt is that the lower edge of the shoulder portion of
the standard safety-belt shall not be lower than the dummy’s elbow at the point of maximum excursion of
the dummy.
Paragraph 6.2.9.
Common understanding is that it applies also to devices that have such a lock-off even if they are not
required for that group. Thus the test would be applied to a Group 2 only device, but at the prescribed
force, i.e. twice the mass of Group 1 dummy.
Paragraph 7.1.3.
The overturning test will be conducted using the same installation procedure and parameters as those
defined for the dynamic test.

Paragraph 7.1.4.2.2.
The wording of this Paragraph refers to accelerations representing tensile loads in the spine of the
dummy.
Paragraph 7.1.4.3.1.
Visible signs of penetration means penetration of the clay by the abdominal insert (under pressure from
the restraint) but not bending of the clay without compression in a horizontal direction as for instance is
brought about by simple bending of the spine. See also interpretation of Paragraph 6.2.4.
Paragraph 7.2.1.5.
The first sentence is complied with if the hand of the dummy could reach the buckle.
Paragraph 7.2.2.1.
This shall be used to ensure that separately approved guide-straps shall be easily attached and
detached.
Paragraph 7.2.4.1.1.
Two straps are required. Measure the breaking load of the first strap. Measure the width of the second
strap at 75% of this load.
Paragraph 7.2.4.4.
Items which may be disassembled or unthreaded and where incorrect reassembly is probable for an
untrained user and could result in a dangerous configuration shall not be allowed.
Paragraph 8.1.2.2.
"Fastened to the seat" means the test seat as prescribed in Annex 6. "Specific devices may" means that
a 'specific' restraint would normally be tested for overturning when installed in the test seat, but that
testing in the vehicle seat was allowed.
Paragraph 8.1.3.6.3.2.
The hinged board or similar flexible device is intended to simulate the removal of clothing from the child
and a failure to re-adjust the harness system. Where the child is restrained by a system that adjusts to fit
the child’s physique without external intervention (where the adult belt is used or the harness contains
automatic or emergency locking retractors), it shall not be necessary to use the hinged board. For child
restraint systems where the length of the straps can be fixed (for example a harness without retractors or
the adult belt is used with a lock-off), the use of the hinged board is required. The hinged board must be
used for the setup of CRS using belted impact shields.

ANNEX 16
CONTROL OF CONFORMITY OF PRODUCTION
1. TESTS
Child restraint systems shall be required to demonstrate compliance with the requirements on
which the following tests are based:
1.1. Verification of the Locking Threshold and Durability of Emergency Locking Retractors
According to the provisions of Paragraph 8.2.4.3. in the most unfavourable direction as
appropriate after having undergone the durability testing detailed in Paragraphs 8.2.4.2.,
8.2.4.4. and 8.2.4.5. as a requirement of Paragraph 7.2.3.2.6.
1.2. Verification of the Durability of Automatically Locking Retractors
According to the provisions of Paragraph 8.2.4.2. supplemented by the tests in
Paragraphs 8.2.4.4. and 8.2.4.5. as a requirement of Paragraph 7.2.3.1.3.
1.3. Test for Strength of Straps after Conditioning
According to the procedure described in Paragraph 7.2.4.2. after conditioning according to the
requirements of Paragraphs 8.2.5.2.1. to 8.2.5.2.5.

2.3. For "built-in" vehicle specific devices, the following test frequencies shall apply:
Child restraints, except booster cushions:
Booster cushions:
Once every 8 weeks
Once every 12 weeks
At each test all requirements according to Paragraphs 7.1.4. and 7.2.1.8.1. shall be fulfilled. If
all tests during one year show satisfactory results, the manufacturer may, after agreement
with the Type Approval Authority, reduce the frequencies as follows:
Child restraints, except booster cushions:
Booster cushions:
Once every 16 weeks
Once every 24 weeks
However, a minimum frequency of one test per year shall be permitted where annual
production is 1,000 child restraint systems or less.
2.3.1. For vehicle-specific devices according to Paragraph 2.1.2.4.1., the child restraint
manufacturer may choose Conformity of Production procedures according to either
Paragraph 2.2., on a test seat, or Paragraph 2.3., in a vehicle body shell.
2.3.2. Where a test sample fails a particular test to which it has been subjected, a further test to the
same requirement shall be carried out on at least three other samples. In the case of dynamic
tests if one of the latter fails, the production is considered to be non-conforming and the
frequency shall be raised to the higher one if the lower one was used according to
Paragraph 2.3. and necessary steps shall be taken to re-establish the conformity of the
production.
2.4. When production is found to be non-conforming according to Paragraphs 2.2.1.4., 2.2.2.4. or
2.3.2. , the holder of the approval or his duly accredited representative shall:
2.4.1. Notify the Type Approval Authority which has granted type approval indicating what steps
have been taken to re-establish the conformity of production.
2.5. The manufacturer shall advise the Type Approval Authority on a quarterly basis, the volume
of products produced against each approval number, providing a means of identifying which
products correspond to that approval number.

2. INSTRUMENTATION
The acceleration shall be recorded during the test, using equipment in accordance with channel
frequency class 1,000 as specified in the latest version of ISO 6487.
3. PROCEDURE
3.1. The assembled child restraint shall be placed in the region of impact on a rigid flat surface,
whose minimum dimensions are 500 × 500mm, so that the direction of impact is perpendicular to
the inner surface of the child restraint system in the area of impact.
3.2. Raise the headform to a height of 100 –0/+5mm from the respective upper surfaces of the
assembled child restraint to the lowest point on the headform, and allow it to fall. Record the
acceleration experienced by the headform during impact.

1. METHOD
1.1. With the webbing set at the reference position described in Paragraph 8.2.7., withdraw at least
50mm of webbing from the integral harness by pulling on the free end of the webbing.
1.2. Attach the adjusted part of the integral harness to the pulling Device A.
1.3. Activate the adjuster and pull at least 150mm of webbing into the integral harness. This
represents half of one cycle and puts pulling Device A to the maximum webbing extraction
position.
1.4. Connect free end of webbing to pulling Device B.
2. THE CYCLE IS:
2.1. Pull B at least 150mm whilst A exerts no tension on the integral harness.
2.2. Activate the adjusters and pull A whilst B exerts no tension on the free end of the webbing.
2.3. At the end of stroke, de-activate the adjuster.
2.4. Repeat cycle as specified in Paragraph 7.2.2.7.

ANNEX 21
DYNAMIC CRASH TEST INSTALLATION
1. METHOD
1.1. Lap Belt Only
Fit load cell 1 to the outboard position as shown above. Install the child restraint and tension
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 250grams. 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.

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.
