Brief analysis of testing standards and methods for flame retardant properties of materials
Flame retardant testing is currently a test that many industries need to test. There are different test standards and methods for different materials. This article briefly describes the flame retardant test standards and testing methods of building materials from the aspect of building materials. 1. Test methods and standards for the flame retardant properties of plastics 1. n Test methods and standards for the flammability of plastics (UL94 flammability test) 2. Determination of the limiting oxygen index of plastics n 3. Determination of smoke generation (Smoke Density Method) n 2. Test method for combustion characteristics of automotive interior materials: FMVSS-U.S. Federal Automobile Safety Standard n SAE-American Society of Mechanical Engineers n ISO 3795-International Standard n GB 8410-China National Standard n and Honda, Nissan, Mitsubishi, Volkswagen , BMW, General Motors, etc. have their own standards. n III. Fire hazard test methods for electronic and electrical products. The live circuit may cause excessive temperature, short circuit, flashover, etc. due to failure, abnormal use or incorrect operation, which may cause the possibility of fire. Commonly used test methods are: · Glow wire test method Glow wire test. ·Needle flame test methods IEC and GB/T have corresponding regulations. 4. Summary of the test method for the combustion performance of building materials·The United States related building materials burning test ASTM vertical furnace combustion standard nUBC standards for heat release of building materials n UL surface burning related standards for building materials n ASTM, NFPA on the criticality of floor materials Radiant flux measurement standard n · The European Union's combustion test of building materials EN The classification of the combustion performance of structural products and building components. nEN The combustion reaction of building materials products n ISO Non-flammability test of building materials n ISO Determination of the heat of combustion of building products n ISO shop Ground material combustion performance test-radiant heat n ·China related building materials burning test GB/T Building materials combustion performance classification method nGB/T Building product combustion performance test-non-combustibility test n GB/T Building material combustion calorific value test method n GB/ T Determination of the combustion performance of floor coverings-radiant heat source method n 5. Summary of the test method for the combustion performance of wires and cables UL Air supply combustion test/Steiner air duct test n UL Upright combustion UL Vertical support test n UL Vertical combustion test n UL Horizontal combustion Test n IEC vertical combustion is similar to n IEC determination of combustion gas amount n GB single wire and cable horizontal burning and inclined burning n GB wire and cable fire resistance characteristics n 6. Summary of test methods for fire retardant coatings. (Applicable to intumescent finish coatings) n has three common methods: large plate combustion method, tunnel combustion method and small chamber combustion method. n 7. Fire performance test methods for furniture and mattresses·Mattress flame retardant test related standards TB mattress cigarette n Mattress open flame (2007, implemented on July 1) n Mattress open flame (implemented on January 1, 2005) n High-risk residential mattress open flame n public residential mattress open flame n ASTM (American Standard) mattress open flame n ·Related standards for the flame retardant test of upholstered furniture TB, BS, ASTM, NFPA Upholstered materials n upholstered furniture (cigarettes), seat Chair (California mandatory), upholstered model or furniture (cigarette). 8. Textile fabric burning performance test method ASTM general fabric burning test method n tent flame retardancy test standard n BS, EN, ISO, GB/T standards on the flame spread of textiles n British pajamas burning test; children's pajamas test standard. n More about flame retardant tester: http://www.standard-groups.com/FlammabilityTesting
