Classification of flame retardant performance testing

Flame retardant products, flame retardant fabrics, flame retardant
The probability of fires in public places is high, so flame retardant measures are essential. However, due to regional and cultural differences, the varieties and specifications of flame retardant products are also diverse in different places. In view of this, after many expert discussions, it was determined that the flame retardant properties of flame retardant products should be tested according to the following classifications.
1. Flame-retardant building products: Building materials products of the same material and structure, if the thicker and thinner materials can meet a certain level of requirements at the same time, Materials with thicknesses in between are considered to meet the requirements of this class. (Flame-retardant flooring materials: of the same material, if thicker and thinner flame-retardant flooring materials can meet a certain level of requirements at the same time, it can be considered that flame-retardant flooring materials with thicknesses in between also meet the requirements of that level.)
2. Flame-retardant fabrics: of the same material, if flame-retardant fabrics with larger and smaller area densities can meet certain requirements at the same time, the area density can be considered to be in between. Flame retardant fabric products also meet the requirements of this level.
3. Flame-retardant plastic/rubber: of the same material, if thicker and thinner flame-retardant plastic products can meet a certain level of requirements at the same time, they can be considered Flame-retardant plastic/rubber products with intermediate thicknesses also meet this class requirement. (Note: When preparing samples, electrical casings, etc. can be sampled from non-abnormally shaped parts with consistent thickness; switches and sockets should be as flat as possible. If the dimensions do not meet the specifications, they can be spliced in appropriate ways.)
4. Flame-retardant foam plastics: Under the same density, if thicker and thinner foam plastic products can meet a certain level of requirements at the same time, it can be considered that the foam plastic products with the middle thickness also meet the requirements. This level requires.
5. Flame-retardant furniture/components: furniture/components of the same material and structure, if large-sized furniture/components meet certain level requirements after inspection , furniture/components of other sizes smaller than it can be considered to also meet the requirements of this level.
6. Wires and cables: If the same type of cables with the same structure (referring to the same inner and outer sheaths, armor layers, filling materials, and insulation materials) are larger and smaller Products with small outer diameters can meet the requirements of a certain level at the same time, and products with intermediate outer diameters can be considered to also meet the requirements of this level.
City Textile mainly produces Flame-retardant fabrics used in Flame-retardant protective clothing strong>, divided into durable flame retardant fabrics and permanent flame retardant fabrics. Among them, the durable flame retardant fabrics mainly include Cotton Proban flame retardant fabric and Cotton CP flame retardant fabric strong>, CVC flame retardant fabrics, Cotton nylon flame retardant fabrics, etc. Permanent flame retardant fabrics mainly use aramid flame retardant fabrics and acrylic cotton flame retardant fabrics. Its flame retardant performance can reach European standards EN11611/EN11612/EN14116, American standards NFPA2112 and many other standards.
