Standard for Flame retardant protective clothing 1, the subject content and scope of application This standard specifies the technical requirements, test methods, inspection rules and requirements for marking, transportation and storage of flame retardant protective clothing. This standard is applicable to hot metal industrial furnaces, machining, welding, chemical, petroleum and other places in the open flame or spark emission or in operation near the molten metal and in combustible materials and fire dangerous places to work, wear clothing with flame retardant (hereinafter referred to as the flame retardant clothing), in order to reduce the human body because of the clothes by the fire burning and damage. 2 terms Flame retardant protective clothing: refers to the direct flame and hot objects, can slow down the spread of flame, the clothes carbonization isolation layer is formed, in order to protect human health and safety of the use of protective clothing. 3 technical requirements 3.1 quality requirements of flame retardant finished products 3.1.1 appearance: clothing quality requirements according to GB2661-81. The strength of the joint or stitching of the 3.1.2 garment: the test shall be carried out according to the method specified in 4.2, and the tensile strength shall be in accordance with table 1. The tensile load of 29.4N (3kg - F) above 3.2 structural design Flame retardant clothing, including caps, clothing, trousers, coats and shoes cover. 3.2.1 general structural design of flame retardant clothing must meet the following requirements. The 3.2.1.1 is lightweight and has a certain firmness, which is beneficial to the human body. 3.2.1.2 easy to wear and relieve, have a certain sense of comfort. 3.2.1.3 flame retardant clothes generally require bright pockets should be covered with clothing, in order to avoid accumulation of splash, molten metal or other pollutants. 3.2.1.4 sewing press GB2661 - 81. 3.2.2 flame retardant clothing must be provided with ventilation pores at the appropriate place to relieve perspiration and regulate body temperature. However, ventilation holes shall not affect the structural strength of the clothing, and the pore structure shall not cause foreign foreign bodies to string into the interior of the garment. 3.3 materials 3.3.1 material requirements: the use of flame retardant finishing and can withstand repeated washing (in the washing machine built-in synthetic washing powder, according to the general laundry concentration, temperature 60 degrees, washing time 15min, washing more than 50 times) fabric. The hot melt and electrostatic discharge and agglomeration fabric shall be. 3.3.2 seam requirements: no synthetic yarn shall be used. 3.3.3 accessories: buttons and hooks should be convenient for connecting and releasing. Hook material shall not use fusible flammable materials (if the hook slot in the clothing inside, not affected by this restriction). 4 test method 4.1 appearance inspection: check whether the garment structure conforms to the requirements of 3.1 and 3.2. The 4.2 parts of the garment by strength test: from four parts of their clothes and trousers suture at the center of the finished specimen width 50mm, length 200mm, will be installed on the tensile testing machine, clamping with width of 50mm, the clamping distance is 150mm, tensile tests were carried out with tensile velocity of 200mm/s, calculate the fracture the load test piece, taking the lowest value as a combination of tensile strength of parts. 4.3 flame retardant test: GB5455 - 85 "vertical method for determining flame retardancy of textile fabrics". 4.4 requirements for flame retardant performance test After flame retardant finishing, the fabric is up to grade two. First class is excellent. After 50 times washing, the test cloth should not be less than three grade. In the test, it is found that the textile products are not qualified when they are melted and contracted. 5 inspection rules 5.1, the production of Flame retardant fabric and the production of flame retardant products need to be designated by the national quality supervision and inspection departments supervision, such as products meet the requirements of this standard, issued a certificate of quality, shall be batch production. 5.2 technical departments designated by the state production of fabric or garment factory and Department of flame retardant products should be regularly tested, when nonconforming product is detected, retest shall be in the same number of products, such as the retest still unqualified, this batch of products to immediately stop the sale, at the disposal of. 5.3, the product in the storage period of three years, the flame retardant performance should be basically stable, the link should be solid and reliable. Extended storage of products should be checked in accordance with the provisions, re identified whether qualified. 5.4 the quality performance test of textile fabrics used by the products shall be undertaken by the corresponding units of the textile department. Responsible for product self inspection by the manufacturer and responsible for the quality of the products. 5.5, clothing products should be cut 1m as a check in the work, such as products at each batch is greater than 10000m, each 10000m should be cut 1m sent to the technical inspection department for future inspection. 5.6, the production of flame retardant manufacturers, production of 2000 sets, when the following 2 sets of inspection, each additional 2000 sets of 2 units will be submitted. 6 signs, transportation and storage 6.1 product packaging should have the following signs: the factory name (or trademark), certificate number, product name, quantity, grade, number, and mass production date, gross weight, package date. 6.2 in the transport and storage process, should avoid exposure to the sun and rain and damp, no corrosive materials together with acid, alkali, oil and storage warehouse, should be kept dry and ventilated, product storage location should be away from the ground and the wall above 200mm h6sTAaRB
