3 Terms and Definitions
For the purposes of this Document, the following terms and definitions apply.
3.1 Flame retardance
The characteristics that, when the sample is burned under specified conditions, the spread of
flame on the sample is only within a limited range after the ignition source is removed, and it
has the capability of preventing or delaying the occurrence or spread of flame.
3.2 Fire resistance
The characteristic that a specimen can continue to operate under specified conditions when it
is burned under specified ignition source and time.
3.3 Halogen free
The characteristic that the halogen (fluorine, chlorine, bromine, iodine) content of the gas
released during combustion is all less than or equal to 1.0 mg/g.
3.4 Low smoke
The characteristic that the concentration of smoke produced by burning does not reduce
visibility (light transmittance) to the extent that it affects escape.
3.5 Low toxicity
The characteristic that the toxic effect and concentration of the toxic fumes produced during
combustion shall not cause the living organisms to die within 30min.
4 General
The combustion characteristics of flame-retardant and fire-resistant wire and cable or optical
fiber cable products shall comply with the requirements of this Standard; and other properties
other than combustion characteristics shall comply with the requirements of the corresponding
product standards.
Wire and cable or optical fiber cable products may reduce their original basic characteristics
while achieving their flame retardance and/or fire resistance purposes, or cause some original
test methods to be inapplicable. All parties using this Standard shall discuss or negotiate a
suitable solution to ensure that the wire and cable or optical fiber cable products achieve the
purpose of flame retardance and/or fire resistance while ensuring safety and reliability during
use. On the premise of without reducing the safety and reliability during use, the corresponding
technical indicators or test methods can be adjusted appropriately.
5 Product Model
5.1 Code and combination of combustion characteristics
5.1.1 Code of combustion characteristics
Halogen-free, low-smoke, flame-retardant wire and cable or optical fiber cable sheathing and /
or insulation can select halogen-free, low-smoke, flame-retardant materials; and the
performance shall be in line with the requirements of relevant product standards. Filling,
wrapping or flame-retardant reinforcement layer and other auxiliary materials shall be selected
appropriately, so that the product meets the requirements of the corresponding flame retardant
category.
The non-metallic materials used by the halogen-free, low-smoke, flame-retardant wire and
cable or optical fiber cable shall meet the requirements of halogen-free performance. The
acidity and electrical conductivity of the released gas, halogen acid gas release or the halogen
content during the combustion of the non-metallic materials shall meet the requirements of 6.3;
the smoke density (minimum transmittance) of the finished products shall meet the
requirements of 6.4.
7.1.3 Halogen-free, low-smoke, low-toxicity flame-retardant wire and cable or optical

The non-metallic materials used by the halogen-free, low smoke and low toxicity flame-
retardant wire and cable or optical fiber cable shall have very little halogen content; the
combustion products are of lower corrosion and toxicity; the combustion products have lower
smoke (higher transmittance). It can be divided into the following categories according to the
flame-retardant characteristics:
--- halogen-free, low smoke, low toxicity, single-piece flame-retardant WDUZ, the single-
piece flame retardance shall meet the requ......
