Introduction to the technical requirements of combustion performance of substances in the world\’s major trading markets

Technical regulations for the combustion performance of textiles and clothing in major trading countries
1. The United States
The United States passed the \"Flammable Fabric Act\" (FFA) way back in 1953 and it was enacted in 1954 and 1967. It was revised and promulgated by the US Congress and enforced by the US Consumer Product Safety Commission (CPSC). Accordingly, CPSC has also formulated: Flammability Standards for Apparel Textiles (16C.F.R.1610); flammability standards for vinyl plastic films (16C.F.R.1611); flammability standards for children\'s pajamas: 0 to 6X (16C.F.R. 1615); flammability standards of children\'s pajamas: Nos. 7 to 14 (16C.F.R.1616), standards for surface flammability of carpet products (16C.F.R.1630), standards for surface flammability of small carpet products (16C.F.R.1631), standard for the flammability of mattresses (16C.F.R.1632).
The above are the mandatory technical standards vto the United States. All related textiles and apparel entering the U.S. market must be tested to these standards and must meet the prescribed flame retardant performance requirements. In addition, some states in the United States also have technical regulations regarding the flame retardancy of textiles, such as California Technical Bulletin No. 117, which is primarily for home decoration textiles, and for porous elastic materials, non-manmade fiber-filled materials, synthetic fiber filled materials, fluffy materials, etc. Flame retardant properties and test methods are specified separately.

(1) Flammability Standard for Wearing Textiles (16C.F.R.1610 is similar to ASTMD1230)
This standard is mainly for wearing textiles (except hats, gloves and shoes), and divides the flammability of the wearing textiles in 3 categories. Level 1: Conventional Flammableid, usually refers to the flame spread time ≥ 3.5 s when the fabric with a flat surface is tested according to the specified method, or the flame spread time ≥ 7 s when the surface fabric is tested according to the specified method, such textiles are suitable for use Clothing; Class 2: Moderately flammable, usually refers to the flame spread time of surface nonwoven fabrics that pass the specified method test, the flame spread time is 4 to 7s, such textiles can also be used in clothing, but caution should be taken; Class 3: rapid and violent combustion, usually refers to the fact that when the surface nonwoven fabric is tested according to the specified method, the flame spread time is less than 4s, and this kind of textile is not suitable for making clothes. If it is detected as highly flammable, such clothing textiles may not be traded and purchased under the regulations. FollowSince the test method in the standard is similar to the American Society for Testing and Materials standard ASTMD1230 (45° tilt method), each test requires 5 samples measuring 5.08 cm (2 inches) × 15.24 cm (6 inches) ), respectively in dry cleaning And test before and after washing.

(2) Standard for flammability of vinyl plastic film
This standard applies to non-rigid, unsupported polyethylene plastic filmMaterial film (including transparent, translucent and opaque, with flat, uneven, patterned or other surface finish ) and polyethylene plastic film with a thickness of ≤0.33mm. It is required that the average combustion speed of five samples in the longitudinal and transverse directions does not exceed 3 cm/s, and the test must be carried out according to the test procedure specified in the standard (45° tilt method), using the SPI combustion tester.

(3) Flammability standard for children\'s pajamas
The flammability standard for children\'s pajamas(0-6X) and the flammability standard for children\'s pajamas (7-14) apply to 0-6X and 7-14, respectively. leotards are not considered children\'s pajamas. The test methods and flame retardant performance requirements stipulated in the two standards are basically the same. It is required to test five 8.9 cm × 25.4 cm samples according to the test method (vertical method) specified in the regulations. The average carbon length of the samples are different More than 17.8 cm (7 inches), the carbon length of a single sample does not exceed 25.4 cm (10 inches). In addition, the regulations also require that all terms of the protection requirements be stated on the safety label of children\'s sleepwear.

(4) Standards for surface combustion performance of carpets and rugs
These two standards are vcan be applied to all types of carpets and rugs. Carpet (carpet) refers to the carpet used in homes, offices or hotels, with a single size > 1.83m and an area of ​​2.23m2. Small rugs (carpet) refer to carpets with a unidirectional size of <1.83m and an area of ​​<2.23m2. The requirements of the two standards are basically the same. It is required that at least 7 of the 8 tested carpets or mats meet the requirements of the standard. The size of the charred portion of a single sample in the test is within the range of 2.54cm. Test methods and procedures are specified in regulations and test reports must be given to retailers or distributors. If the carpet or its fibers have a flame retardant finish, a \"T\" should be listed on the label.

(5) Combustion Performance Standard for Mattresses
The mattresses in this standard include portable, double-layer waterbeds withcore, air mattresses, sofa beds etc. for adults, teens and babies. But cotton wool covers such as sleeping bags, pillows, beds and sofas filled with liquid or gas are excluded. Test according to the method specified in this standard (cigarette method), if the carbon length in any direction around the cigarette does not exceed 50.8 mm (2 inches), then the test site of a single cigarette is qualified. It is generally required to light 18 cigarettes to test, as long as any part does not meet the standard, the mattress is not qualified. In addition, the regulations require mattresses treated with flame retardants to be marked with a \"T\" on their labels.

2. Canada
Canada\'s regulations regarding the flame retardancy of textiles and clothing are contained in the Dangerous Goods Regulations and Regulations.Products (Children\'s Sleepwear) Regulations, Hazardous Products (Carpets) Regulations,VoHazardous Products Regulations (Tents), Hazardous Products Regulations (Toys) and Hazardous Products Regulations (Mattresses), these Regulations must strictly comply with the provisions of the Hazardous Products Regulations, but the Hazardous Products Regulations are also based on Canada is responsible for sending inspectors to enforce laws and regulations on hazardous products.
(1) \"Regulations on Dangerous Products\"
The \"Regulations on Dangerous Products\" stipulate that all flammable, toxic and other products that pose a threat to public health and safety are dangerous products, and textiles and clothing must also belong to them. This regulation requires that if plain textile fiber products are tested according to ASTM D1230, if the surface is flat fabric, the flame spread time should be greater than 3.5s; if the surface is a stacked fabric, moet the flame spread time is longer than 4 s . For children\'s pajamas, pillows, cots, cribs or other sleep textiles with a size ≤ 14X, when tested according to ASTMD1230, the flame spread time must be greater than 7 s. For various carpets, rugs and blankets, etc., according to Canada The Canadian Government Specification Board (CGSB) standard CAN/CGSB-4.2No.27.6-M84 is tested and the test results of the samples must fall within the range specified specified in standard 4-GP-155M.
(2) \"Dangerous Products Regulations (Children\'s Pajamas)\"
The \"Dangerous Products Regulations (Children\'s Pajamas)\" define the flame-retardant properties, test methods and flame-retardant labels of children\'s pajamas. After testing according to the test method specified in the regulation, the results must meet the following requirements: 1) The average carbon length of 5 samples must not exceed 178 mm; 2) The carbon length of a maximum of 1 sample must be equalto the total length of the sample (254 mm).
Children\'s pajamas treated with flame retardant must be attached with a safety label, clearly indicating the flame retardant (flame retardant), and the product manual must be written in English and French, and the cleaning process must be carried out in particular to ensure that the product is delivered to the agent. The flame retardancy of the product will not be reduced after commercial use or use.
(3) \"Regulations for hazardous products (carpet)\"
The \"Regulations for hazardous products (carpet)\" have no special regulations for the flame retardancy of carpets, but require flammability warnings on the labels of carpet textiles . If the size of the carpet is > 2.16 m2 or the length > 1.8 m or if the carpet is combined, the label must read: \"Caution - Flammable - Do not use in places with open flames or high temperatures\" ; like the carpett not used indoors, indicate on the label: \"Caution - Flammable - Do not use near open flame or high temperature, and it is forbidden to use indoors\". In English and French, the font should be clear and eye-catching.
(4) \"Hazardous products (tents) regulations\"
The \"Hazardous products (tents) regulations\" determine the flame retardant properties of tent textile materials. The regulation adopts the CPAI-84 standard issued by the Industrial Textiles Association in 1980, which is a specification for flame retardant materials used in tents. Test tent materials according to CPAI-84, and the flame retardant performance requirements are as follows: 1) The damaged length of the crushed material does not exceed 25mm; The afterflame time must not exceed 2s; the damaged length of a single sample should not exceed 255mm, and the average damaged length of the sample will have different specified rangesam, depending on the square meter weight of the sample.
In addition, the regulations also stipulate that the safety labels of tent products must indicate the prescribed language for flammability warnings, in clear and prominent fonts, and expressed in English and French.
(5) \"Regulations for dangerous products (toys)\"
The \"Regulations for dangerous products (toys)\" contains specific regulations for the flame-retardant performance requirements and test methods of soft toys made of textile fiber materials. Test the sample according to the test procedures specified in the regulations and the flame spread time should be longer than 7s. 5 samples should be tested each time, if 1 fails, test another 5 samples, if 2 out of 10 samples fail, it means the product does not meet the requirements of the regulation.
(6) \"Hazardous Products (Mattresses) Regulations\"
The \"Hazardous Products (Mattresses) Rregulations\" stipulate that mattress products must meet Canadian standard CAN/CGSB–4.2No.27.7– before being placed on the market for sale M89 test (cigarette method), the length of carbonization or char in any direction around the cigarette must not be larger than 50mm, and after the cigarette is extinguished, the sample should not continue to burn for more than 10 minutes.
3. Japan
Japan has no special requirements for flame retardant performance on clothing products, but it specifies flame retardant performance on textiles such as carpets and curtains in most commercial buildings, and the specific regulations are contained in the fire protection law.The fire law requires that curtains and carpet textiles used in public buildings and places requiring fire protection must have certain flame retardant properties, and it is determined that carpets with a size of 2m2 or more must pass the Japan Flame Retardant Test and Certificationsole. The regulations also stipulate that any carpets or curtains with flame retardant properties must have the specified \"fire resistant mark\".
4. Australia
Each state in Australia has its own technical regulations. With regard to the flame retardant performance of textiles and clothing, Western Australia (Western Australia) has adopted the \"Fair Trade Act 1987\" and \"Fair Trade (Children\'s Evening Wear and Products Information Standards) Regulations 1988\", Tasmania has adopted the \"Flammable Clothing Act 1973\" and \"Flammable Clothing Regulations 2002\" issued, New South Wales (NewSouthWales) issued the \"Fair Trade (General Requirements) Regulations 2002. These technical regulations primarily govern the flame retardant performance and testing methods of children\'s evening wear with sizes between 0 and 14 Children\'s evening wear, including children\'s pajamas, nightgowns, bathrobes and baby sleeping bags, shall be tested in accordance with the methods specified in AS/NZS1249 and must meet the safety requirements for evening wear for children in this standardRequire.
5, United Kingdom
The United Kingdom is setting stricter requirements for the flame retardant safety of evening wear.The Evening Wear (Safety) (Amendment) Regulations came into force in 1987 and apply to all clothing worn as evening wear. .
The regulations require that the combustion performance of children\'s evening wear (clothing for children aged between 3 months and 13 years) must meet the requirements of British Standard BS5722 and be tested in accordance with the provisions of BS5438. Baby clothes (under 3 months) and evening wear for adults must have a safety label stating whether they meet the flammability standard. If eveningwear is finished with a flame retardant it must have an appropriate warning label indicating washability or suitable detergents. Before testingon flammability, it should be washed following the cleaning procedure in BS5651.
This Regulation has been made under the general provisions of the Consumer Safety Act 1978 and it will be considered an offense to supply goods in breach of this Safety Regulation.
