Classification inspection methods for flame retardant properties of flame retardant products

Classification:
flame retardant fabric

There are various varieties and specifications of Flame-retardant products in public places. How to test the flame-retardant performance of these tens of thousands of flame-retardant products is a An issue of common concern to everyone. After many expert discussions, it was determined that the flame retardant properties of flame retardant products should be tested according to the following categories.

Flame-retardant building products:

For building materials products of the same material and structure, if thick and thin materials can meet the requirements of a certain level at the same time, it can be considered that materials with thicknesses in between can also meet the level. Require. (Flame-retardantPaving materials: the same material, such as thick and thin flame-retardant flooring materialsIf it can meet the requirements of a certain level at the same time, it can be considered that flame-retardant flooring materials with thicknesses in the middle also meet the requirements of that level.)

Flame retardant fabric:

For the same material, if the flame-retardant fabrics with large and small area densities can meet a certain level of requirements at the same time, it can be considered that flame-retardant fabric products with area densities in the middle also meet the requirements. Level requirements.

Flame retardant plastic/rubber:

If thick and thin Flame-retardant plastic products of the same material can meet a certain level of requirements at the same time, the thickness can be considered to be in between‘s flame-retardant plastic/rubber products also meet the requirements of this level. (Note: When preparing samples, electrical casings can be sampled from non-special-shaped parts with consistent thickness; switches and sockets should be sampled from flat parts as much as possible. If the dimensions do not meet the specifications , can be spliced in appropriate ways.)

Flame retardant foam:

Under the same density, if thick and thin foam plastic products can meet the requirements of a certain level at the same time, it can be considered that the intermediate thickness foam plastic products also meet the level. Require.

Flame RetardantFurniture/Components ：

For furniture/components of the same material and structure, if the large-sized furniture/component meets a certain level of requirements upon inspection, it maybe considered smaller than that of other sizes. Furniture/components also meet this class requirement.

Wire and cable:

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) with large and small outerdiameters can reach a certain level at the same time requirements, it can be considered that products with intermediate outer diameters also meet the requirements of this grade.

LimitedproducedFlame-retardant fabrics are comfortable and safe, and various fabrics can be customized according to your needs.
