Comparison of flame retardant performance and flame retardant standards of flame retardant clothing fabrics

BS EN
11612 Chinese full name: Protective clothing for workers operating in high temperature environments Flame-retardant protective clothing standard (not Suitable for welder clothing and firefighting clothing)
Testing methods and judgment standards:
Judgment criteria: The test sample cannot burn to its top or edge.
There should be no holes formed in the test specimen.
There should be no burning droplets or molten droplets falling on the test sample.
The flame delay time should be less than or equal to 2 seconds.
The smoldering time should be less than or equal to 2 seconds.
Testing method: Before conducting the short-term spreading combustion test, the method described in ISO6330 should be used to dissolve the sample in water with 1g/l IEC detergent, then put the sample into the washing machine and wash it 5 times in the machine, and then dry it immediately. If there are no special provisions on the instructions for use label, washing should be carried out according to method 2A at 60°C, and drying should be carried out according to method E (cylinder drying). The testing center can test more test items, including the flame retardant performance of flame retardant fabrics, shrinkage, color fastness, strength, formaldehyde content, etc.

In compliance with ISO3175 regulations, dry-cleaning fabrics should be labeled and only dry-cleaned 5 times. If the fabric or suit does not have a label, the fabric will be tested individually after 5 washes and dry cleaning.

Perform fabric pre-treatment according to the method, and then perform ignition testing according to the EN532 method.
※
Fabric size change requirements: According to the requirements of EN340, the shrinkage and deformation of the fabric after 5 washes, in accordance with the instructions of the garment factory, should not exceed 3% in the warp direction and 3% in the weft direction. .

CA-117 is a widely used one-time fire protection standard in the United States. It does not require post-water testing and is applicable to most textiles exported to the United States. US CS-191 is the general fire protection standard for protective clothing in the United States, emphasizing long-term fire protection performance and wearing comfort. The processing technology is usually a two-step synthesis method or a multi-step synthesis method, which has high technical content and profit added value. The United States NFPA-701 and 703 are fire protection standards published by the National Fire Protection Association. They are applicable to hanging fabrics such as curtains in public places that do not require water resistance. The test also requires physical and chemical indicators such as dry adsorption capacity and hand feel. The full name of American TB-603 is BHFTI
CTB-603
It will be implemented in the United States on January 1, 2005. Mainly used for mattresses, mattresses and other bedding products. The test method is: use the large chamber combustion method to test the heat release value of a complete mattress (mattress). US NFPA261.94 is suitable for furniture covering strong objects, including sofas, etc.
