What standards can flame retardant fabrics meet?

Flame retardant cloth is a cloth that automatically extinguishes within 12 seconds of leaving the flame even if it is lit by an open flame. According to the order of adding flame retardant materials, there are two types: pre-treatment flame retardant cloth and post-treatment flame retardant cloth.

GB8965-2009 is the new Chinese national flame retardant clothing standard;

Standard GA10-91 Performance Requirements and Test Methods for General Protective Clothing for Firefighters in China issued by the Ministry of Public Security of the People's Republic of China Standard for Ordinary Protective Clothing for Fire Fighters.

EN531: The EU standard for industrial thermal protective clothing stipulates the overall performance, structural design, dimensional stability, flame spread, heat resistance and molten metal properties, size marking and shipping marks, user information, identification patterns, etc.

EN470-1: The EU standard for thermal protective clothing for welders and similar types of work specifies the design requirements, material requirements, safety requirements, size marking and shipping marks, user information, identification patterns, etc. of flame retardant clothing.

EN479 EU Standard for Fire Protective Clothing This standard specifies the standard for protective clothing for structural fires, with the main consideration being protection against heat and flame. This standard does not cover special tasks such as spill chemical removal, forest fires, close fire fighting, road accident rescue and other special fire risk protection. The standard includes general requirements, important safety requirements, additional requirements, marking marks, user information and identification patterns.

NFPA 2112: American Fire Protection Association Flame Retardant Clothing Standard The American Fire Protection Association specifies Industrial Flash Fire flame retardant protective clothing in the following areas: product marking, user information, clothing design, fibers, stitching, accessories accessories, signage.

FMVSS302 is mainly suitable for flame retardant testing of automotive interior materials.

UL94 is widely used for flame retardant testing of plastic materials.

EN13501-1 fire rating test standard for general materials.

EN13501-1 Class A1: Tested and compliant according to ISO EN 1182 and EN ISO 1716.

EN13501-1 Class A2: Tested and compliant according to ISO EN 1182, EN ISO 1716 and ISO EN 13823.

EN13501-1 Class B, C, D: Tested and compliant according to ISO EN 13823, ISO EN 11925-2.

EN13501-1 Class E: Tested and compliant according to ISO EN 11925-2.

EN13501-1 Class F: Tested according to ISO EN 11925-2 but does not meet the requirements.

Legal analysis: There are two national standards for flame retardant products in China:

1. GB 20286-2006 --- requirements and labels for the combustion performance of flame retardant products and components in public places.

2. GB 8624-2006 --- classification of combustion performance of building materials and products.

Requirements: The sample can quickly self-extinguish from ignition to non-burning melt dripping for a certain time interval after the flame is removed (i.e., the burning melt drips on a one-foot cotton pad located one foot below the test sample and cannot ignite the cotton).

The key to the greening of flame retardant materials is the selection of flame retardants. The green and sustainable development direction of flame retardants should be non-PBT and non-CMR substances, rather than bromine-free or halogen-free. Polymeric or macromolecular flame retardants have become a hot development direction of green flame retardants due to their innate low toxicity and non-bioaccumulation in structure.

Legal basis: Measures of the People's Republic of China for the Administration of Industry Standards

Article 1 In order to strengthen the management of industry standards and ensure the coordination and unification of industry standards, these measures are formulated in accordance with the provisions of the Standardization Law of the People's Republic of China and the Regulations on the Implementation of the Standardization Law of the People's Republic of China.

Article 2 The industry standard is a standard formulated for the technical requirements that do not have a national standard and need to be unified within a certain industry in the country. Industry standards shall not contradict relevant national standards. Relevant industry standards should be coordinated and unified, and should not be duplicated.

Industry standards shall be abolished after the implementation of the corresponding national standards.

Article 3 The following technical requirements that need to be unified within the industry can be formulated industry standards (including the production of standard samples):

1) Technical terms, symbols, codes (including **), file formats, drawing methods and other common technical languages;

2) The varieties, specifications, performance parameters, quality indicators, test methods, and safety and health requirements of industrial and agricultural products;

3) Design, production, inspection, packaging, storage, transportation, use, and maintenance methods of industrial and agricultural products, as well as safety and health requirements in the process of production, storage, and transportation;

4) Technical requirements for general parts;

5) Product structure elements and interchange and coordination requirements;

7) Technical requirements for information, energy, resources, transportation, and their management technology.

The difference between flame retardant grade BFL and B1 of floor materialsThe flame retardant and fire retardant performance of building materials is the primary indicator related to the safety of life and property. As one of the building materials, the paving material is no exception, and the state has issued a number of standards to regulate and constrain, and the flame retardant performance of flame retardant and fireproof paving materials has been clearly stipulated. However, at present, the flame retardant grade of the best colored rubber flooring and PVC plastic flooring on the market is very confusing and has different interpretations.

There are even some irresponsible people, and even misleading the BFL level in the latest national standard GB8624-2006 as equivalent to the B1 level of the original GB8624-1997 or even the B1 level of the German standard DIN 4102-1, etc., which is very misleading to customers. Regardless of the fact that it is not possible to easily correspond to different standards, and even in terms of the values of indicators that can be compared with each other, BFL and B1 are very different. China's original standard GB8624-1997 is mainly compiled with reference to Germany's DIN4102-1, but China's B1 grade is also different from Germany's B1 grade, China's B1 grade has one more tobacco production (smoke density) index than Germany's B1 grade, which can be said to be more demanding.

With the introduction of the new unified standard EN13501-1:2002 of the European Union, the German DIN 4102-1 has been abolished. In response to this change, China has recompiled the new national standard GB8624-2006 with reference to the new EU standard, which divides the flame retardant grade of paving materials into A1FL, A2FL, BFL, CFL, DFL, EFL and FFL.

This is currently the most demanding flame retardant material standard in the world. The critical thermal radiation flux measured by the heat source method is the most critical indicator of the flame retardant performance of the reaction paving material, from the critical thermal radiation flux (CHF) alone, the BFL level requirements of GB8624-2006, and the B1 level requirements of GB8624-1997 and the B1 level of German DIN 4102-1 are only, far from the difference, only equivalent to the CFL requirements of GB8624-2006, which is not a grade index at all. Therefore, the so-called BFL is the original B1, either out of ignorance, or because the flame retardant performance of the product itself does not reach the BFL level and deliberately misleads customers.

Comparison table of the main indicators of the old and new classifications, flame retardant grade standards, street heat radiation flux, smoke toxicity, tobacco production, German detection is not detected, China detection is less than or equal to 750% * min, China detection is less than or equal to 750% * min, China detection is less than or equal to 750% * min, China detection is less than or equal to 750% * min, from the above **, we can clearly see the difference between German B1 grade, Chinese B1 grade, and Chinese BFL grade. Personally, I recommend Aiju's ** is very good, and I recommend that you also go there to see, which will help your questions.

At present, the national standard for the fire rating test standard of building decoration materials GB 8624-2012, if it is the main test of ground materials critical radiation and small ignition source test, you can contact the laboratory for consultation.

General industry standards? Is it GB GB8965-98?
