Chemical Methods of Test Sectional Committee, TX 05

FOREWORD
This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized
Methods of Test Sectional Committee had been approved by the Textile Division Council.

by the Chemical

There have been many fire incidents in recent years in public buildings/places, the origin of which could be many such
as electric short circuiting, ignition, etc. The origin of fire may not be that much dangerous and hazardous ,as the ease
of ignition and spreading of fire due to combustible materials such as curtains and drapes and othe~ textilt%, plastics,
upholstered furniture, etc. Depending upon the type of materials encountered in burning, its ease of ignition and its fire
spread properties, the extent of damage to the life and property could be enormous. In order to prevent or minimize the
dalmage to life and property due to such fire risks, formulation of standard for resistance to ignition of curtains and
drapes in public placewbuildings needs no emphasis.
It needs to be borne in mind that measures to reduce the ignitability ofa textile or textile assembly may adversely affect
other firo properties such as smokeand toxic gas evolutionand this aspect mayrequireconsiderationwhen materials

andconstructiontechniquesare beingevaluated.Therefore,it is desirablethat the finishingmaterialsusedforvarious

surfaces and decorations including textiles should be such that it does not generate toxic smokeand/or fhrnes,
Specification for resistance to ignition of textile materials and assemblies for use in the public buildings/places exist in
vario~s developed countries as a fall out of various legislation, rules or acts, etc, or directions of local bodies. The trend
is increasing in other countries also and India should be no exception to this. This standard lays emphasis on matching
the magnitude of threat posed in various places/buiIdings with commensurate performance levels of fire resistant textile
materials for curtains and drapes so as to ensure safety of the life and property. The list of buildings/places under
different fire hazards categories has been included as per SP 7:2005 National Building Code of India 2005.
The composition of the Committee responsible

for the formulation of this standard is given in Annex C.

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed
or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with 1S 2: 1960 Rules for
rounding off numerical values (revised). The number of significant places retained in the rounded off value should be
the same as that of the specified value in this standard.

TEXTILES RESISTANCE TO IGNITION OF CURTAINS
AND DRAPES SPECIFICATION
NOTE The ignitability performance specified for curtains
and drapes for different end-uses varies according to the level
of risk associated with a particular environment as shown in
Table 1.

1 SCOPE
1.1 This standard
specifies
requirements
for the
resistance to ignition of curtains and drapes used for public
places/buildings.
NOTE The levels of ignition resistance have been set afler
careful consideration of the fire risk of the partictdar end-use
environment involved. These levels do not necessarily reflect
the behaviour of curtains and drapes in a fully developed fire.

1.2 Curtains and drapes for domestic use and transport

are not covered

in this standard.

4.2 Durability

Carry out the water soakhg treatment by subjecting the

curtains and drapes to the water soaking procedure
described in IS 12467 (Part 1) or IS 12467 (Part 2) except
that the test specimen shall be dried by any method suitable
for the fabric type before it is conditioned prior to testing
in accordance withIS6359.
5 SAMPLING

particular

premises

of Treatment

is given in the notes in Table 1,

5.1 Lot
2 REFERENCES

The quantity of identical type of curtains and drapes

manufactured under similar conditions and supplied to a
buyer against one dispatch note shall constitute a lot.

The standards given in AnnexA contain provisions which,

through reference in this text, constitute provisions of

this standard. At the time of publication, the edition;
indicated were valid. All standards are subject to revision
and parties to agreements based on this standard are
encouraged to investigate the possibility of applying the
most recent editions of the standards.

NOTE Identical type means that there has been no major

basic alteration to the material specification,
that is, the fibre
content, weave and mass per unit area of fabric. Changes in the
colour of a product or minor changes in the pattern or weave,
for example, of the order of 2 picks/cm may be disregarded,

5.2 Random sample from the lot shall be drawn as per

relevant Indian Standard or as agreed to between the buyer
and the seller.

3 TERMINOLOGY
For the purposes of this standard the definitions given in
SP 45 and the following shall apply.

5.3 The sampling of the material shall be done as specified

in the relevant material specification or as agreed to between
the buyer and the seller. In the absence of relevant standard
on material specification or agreement between the buyer
and the seller, the curtains and drapes shall be tested atler
every 2500 units produced or once per month, whichever
is the more practicable, in accordance with IS 15612 (Parts
2 to 4). Re-testing shall be carried out where there is any
major basic alteration to a material specification (for example
of fibre content, weave or mass per unit area of fabric).
Changes in the colour of a product or minor changes in
the pattern or weave, for example of the order of 2 picksl
cm, shall not be deemed sufficient reasons to necessitate
re-testing.

3.1 Fire Hazard Potential for loss of life (or injury)

and.lor damage to property, by tire.
3.2 Fire Risk Probability of fire causing loss of life
(or injury) and/or darnage to property.
3.3 Ignition Risk The probability that ignition will
result if a source of heat is allowed into close proximity or
contact with a combustible material.

NOTES
I It is important to realize that the listing of types of premises under different hazard categories in Table 1 is given for guidance only
and that the classification of a particular premises into one of the hazard categories is a decision for staff responsible for fire safety.

The examples cited in Table 1 for each hazard category cannot be exhaustive and do not cover all types of possible premises in
a hazard category. It will be noted that some of the examples appear in more than one hazard category. This reflects the range of
hazards possible under different circumstances for particular types of premises. Other examples, whether or not listed in Table 1, could
also fal I into more than one hazard category. Howevec when all the relevant factots have been considered, a particular premises can
then be assigned to one hazard category.
3 The classification of a particular premises into one of the hazard categories in Table 1 is a decision for staff responsible for fire
safety, for example, bui Iding control, fire brigade, licensing authorities, or environmental health authorities. Their classifications may
be ditTerent from the examples given in Table 1. Attention is drawn to the following when classifying a hazard area:
a) Statutory
b) Building

requirements
regulations

and other recommendations;

and local authority

bye-laws;

c) Regulations;
d) Consumer

protection

acts and safety;

m) Level of occupancy;
n) Whether, in the case of fire, occupants could be expected on their own or whether they would need assistance,
babies, children, old and infirm, the invalid, the sick, and those retained by locked doors;
P ) Presence

or absence

of an automatic

tire detection

and alarm system, or an automatic

fire extinguishing

for example,

system;

q) Any special hazards, such as cooking, heating, live flame effects, smoke effects, low lighting levels, strobe lighting, loud music,
drinking, use after dark;
r) Whether or not the premises
and
s) I.ocation

are, during times of use, under the control of staff trained in appropriate

evacuation

procedures;

of the hazard area, namely, of floors, whether or not high rise and/or below ground sod/or windowless.

4 Flame retardant treatments are sometimes applied to curtains and drapes to improve resistance to ignition. Those responsible for
controlling these textile materials need to be satisfied that such treatment will continue to be effecfive and will not deteriorate in use.
The tests described in 4.2 are designed to show whether such an added flame retardant is likely to be affected by contact with water and/
or by any dry cleaning process, and can be taken as a general guide to the overall permanence of a flame rttardant treatment.
If a particular premises in a low hazard area is also used for sleeping purposes then that premises shall assigned a higher hazarti category.
