EN 533 EN 533 clothing fire detection of Chinese name: tooling protective clothing - fabrics and related assemblies - heat and fire - short detection method to detect the spread of combustion performance and criteria: Criteria: three criteria Index Index 1: Detection After the sample was ignited, the flame does not burn and spread to the top or the bottom of the vertical edge of the fabric sample; can produce holes in the sample but not the top of the cloth or damage to the vertical edge of the fabric; can not have burning debris (droplet) falling from the cloth; stop burning after the flame is removed, smoldering carbonization zone should extend from the fabric to the undamaged area of ??the fabric. Index 2: After detection sample ignited, flames spread to the sample can not burn the bottom or the top of the vertical edge of the fabric; not burning debris (droplet) falling from the cloth; remove the flame stopped burning, Smoldering carbonization zone should extend from the fabric to the undamaged area of ??the fabric; no holes produce. Index 3: The post-test sample was ignited, flames spread to the sample can not burn the bottom or the top of the vertical edge of the fabric; not burning debris (droplet) falling from the cloth; remove the flame stopped burning, Smoldering carbonization zone should extend from the fabric to the undamaged area of ??the fabric; no holes produce; retardant detected in the sample period of six blocks of any piece of not more than two seconds. Detection methods based on EN532 standards: Preparation for testing samples: Long (200 ± 1) mm X width (160 ± 1) mm detected before washing requirements: A. 75 ℃ washed 12 times (in compliance with EN ISO 10528 industrial washing method ); also according to customer requirements washed five times, then be detected. B. The sample was soaked in water (BS 5651: 1978), then in accordance with the requirements of ISO 3175 dry cleaning five times, then be detected. ※ This method is suitable for chemical fiber, cotton and blended fabrics.
