Carpet, Floor Covering Material Flame Retardant Test

Carpet, Floor Covering Material Flame Retardant Test

In China, the test types of paving materials are mainly flooring, carpets, floor tiles and other major categories. Flooring is mainly solid wood flooring, composite wood flooring, solid wood composite wood flooring, bamboo flooring, cork flooring, mute flooring, plastic flooring, etc.; carpet according to the texture is divided into pure wool carpet, blended carpet, synthetic fiber carpets, plastic carpets, grass carpets, etc., according to the weaving process is divided into woven carpets, tufted carpets, glued carpets, hand-woven carpets, etc.; tiles are generally divided into polished tiles, glazed tiles, tiles, mosaics, etc., common products are antique tiles, glazed flowers, microcrystalline fused block tiles, and other products are antique tiles, glazed flowers, microcrystalline fused block tiles. Common products are antique tiles, glazed flowers, microcrystalline fused stone, porcelain visits, crystal tiles, matte tiles, travertine tiles and so on.

Want to evaluate and test the combustion performance level of paving materials, we must first according to the national mandatory standard GB 8624-2012 in the implementation of the provisions of the GB 8624-2012 will be ordinary material combustion level is divided into A level, B1 level, B2 level, B3 level. Among them, Grade A is divided into two levels, A1 and A2; Grade B1 is divided into two levels, B and C; Grade B2 is divided into two levels, D and E; and Grade B3 is Grade F, with no performance requirements. The combustion performance test of paving materials requires that the maximum time should be 30 minutes.

The indexes of the combustion test of paving materials, that is, the basis of combustion level grading are mainly temperature rise in the furnace, mass loss rate, duration of combustion time, total calorific value, critical thermal radiation flux, 20s flame tip height, etc. The detailed requirements are as follows. Detailed requirements are as follows: additional information about combustion performance in the test report of paving materials should include smoke production characteristics, combustion droplets, particulate levels, smoke toxicity levels. Especially for A2, B, C combustion class paving materials must have the two information of smoke production characteristics and smoke toxicity.

Smoke production characteristics can be based on GB/T 11785-2005 "combustion performance of paving materials radiation heat source method" in the test method to detect. Smoke toxicity is mainly divided into t0, t1, t2 three levels, the test method can be based on GB/T 20285-2006 "material smoke toxicity hazard classification" in the provisions of the implementation.
