Test standards for flame retardant tear strength of flame retardant clothing

Technical indicators and uses of flame-retardant clothing Main technical indicators Thermal protection coefficient: Class A: ≥126TPP/(kw·s/m2) in direct contact with skin, ≥250TPP/(kw·s/m2) if there is a gap between skin and clothing ; B level one; C level one. Flame retardancy: afterburning time A level ≤ 2s, B level ≤ 2s, C level ≤ 5s; smoldering time A level ≤ 2s, B level ≤ 2s, C level ≤ 5s; damage length: A level ≤ 50mm, B level ≤100mm, grade C ≤150mm; no melting or dripping. Breaking strength: ≥450N before washing, ≥400N after washing. Tear strength: ≥25N before washing. Moisture permeability: ≥6000g/(m2·24h). Bending length: ≤3c. The dimensional change rate of water washing is +2.5%~-2.5%.
Usage: It can be widely used in oil fields, metallurgy, electric welding, machinery, firefighting and other workplaces that have obvious special requirements for clothing. Test standards and tests for flame retardant clothing
