Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard has been prepared in accordance with NFPA 701.2015 "Standard Methods for Fire Tests for Textile and Film Flame Propagation" Method 1 (English)
Text version), this standard is modified to adopt NFPA701.2015 (TM1).
This standard makes the following changes to the method 1 part of NFPA 701.2015.
--- Removed 8.3.6.1 from the original standard;

Import and export textile suspension materials resistant to flame propagation
Test standard method open test box method
1 Scope
This standard specifies the test method for open test boxes for the flame propagation resistance of suspended materials in textiles. Under greater flame exposure conditions,
Or when used under different test conditions, this standard method should not be considered to characterize the ability of the material to be tested to resist flame propagation.
This standard applies to hanging fabrics or other materials used in curtains, decoration or other windows. It can be a single layer of fabric or
Is a multi-layer curtain or decoration, whether it is stitched or otherwise combined, the fabric weight is required to be no more than 700g/m2 (see
Appendix A).

3 Terms and definitions
The following terms and definitions as defined in GB/T 3291.3 apply to this document.
3.1
Decorative materials
A material that hangs from a wall, ceiling, or structural unit to create a decoration, sound, or other effect.
3.2
Textile textile
A fabric made of natural or synthetic fibers.
4 Principle
After the sample was adjusted and weighed, it was hung vertically in the open test chamber and contacted with the specified flame for 45 s. When the flame self-extinguishes or
When no further sample damage occurred, the sample was taken out to room temperature and weighed again. Calculate the percentage of weight loss used to characterize the total
Body flame spread and the extent of sample damage.
5 Equipment and materials
5.1 Oven
It is capable of forced blasting and the temperature inside the chamber is (105 ± 3) °C, which is used to test the front balance test sample.
