Flammability Test

Flammability Test is a standardized test that evaluates the burning characteristics of materials or products when exposed to a fire source. In foreign trade, it is commonly used for textiles, plastics, electronic appliances, furniture, building materials, and other categories. Its core purpose is to measure indicators such as burning rate, afterflame time, afterglow time, and damaged length to determine whether they comply with the fire safety regulations or standards of the target market, such as NFPA 701, FMVSS 302, and UL 94 in the United States, and EN 13501 and EN 71-2 in the European Union. Use scenarios include: test reports required for customs clearance in the importing country, fire ratings agreed upon by buyers in procurement contracts, or compliance documents mandatorily required by e-commerce platforms such as Amazon. Notes: The test must be issued by an ISO/IEC 17025 accredited laboratory, and the report must include the standard number, sample description, test date, and conclusion; standards vary greatly across markets and cannot be used interchangeably; the test sample should be consistent with the bulk goods, otherwise the report is invalid. Difference from 'flame retardant test': Flammability Test focuses on the overall performance of a material in resisting combustion, while flame retardant test focuses more on self-extinguishing properties after flame retardants are added. Difference from 'fire resistance test': Fire resistance test targets the structural integrity of building components under high temperatures, with longer duration and stricter requirements.
