Related standards for automotive textiles
Vehicle textiles include seat cushions, foot pads, car carpets, automotive decorative cloth, seat cloth, seat belts, automotive soft roof and so on, but it is not easy to see include: airbags, tire cord fabric and so on. Each car uses about 20-25 kilograms of textiles, and buses use more, so the use of automotive textiles is huge. With the development of China's automobile industry, the consumption of automotive textiles is increasing year by year.
China's textile production enterprises hope to enter the field of automotive textiles, but the automotive industry is relatively special, the requirements for related components are very high, and different manufacturers have different requirements. Therefore, as a cross industry product standard, it has become a high threshold for enterprises to enter this field. The author consulted the relevant national, domestic and foreign testing institutions, at present only a few SGS testing institutions, master the relevant standards at home and abroad, and can provide relevant testing.
Experts said: at present, domestic standards related to automotive textiles are mainly the following:
1. National mandatory standard GB 8410-2006 combustion characteristics of automotive interior materials.
The standard specifies the technical requirements and test methods for the horizontal combustion characteristics of automotive interior materials. This standard is applicable to the evaluation of horizontal combustion characteristics of automotive interior materials. In view of the many differences between the actual conditions of various automotive interior parts (parts application parts, layout methods, use conditions, ignition sources, etc.) and the test conditions stipulated in this standard, this standard is not applicable to evaluate all the real combustion characteristics of automotive interior materials.
2. GB 14166-2003 safety belt and restraint system for adult occupants of motor vehicles
The standard specifies the definitions, technical requirements and test methods of automotive seat belts and restraint systems, which are suitable for mounting on M and N vehicles and are used separately by front-to-adult passengers as independent equipment.
3, QB/T 2971-2008 auto trim sheep shearing products.
The standards specify the classification, requirements, test methods, inspection rules, packaging, marking, transportation and storage of sheep shearing products for automobile decoration. This standard is applicable to sheep shearing products for automobile decoration. This standard is also applicable to other fur products used for automobile decoration.
4, FZ/T 34008-2009 car linen cushion.
The standard specifies the technical requirements, test methods, inspection rules, marks, packaging and transportation of linen cushions for automobiles. This standard is applicable to machine woven and hand woven cushions with flax fiber content of 50% or more.
When talking about the relevant standards and requirements of foreign countries, experts said that the development of foreign automobile industry is earlier, different from our country's situation. Foreign manufacturers usually have their own standards, and the test methods are different. For example, the wear resistance, anti-fuzzing, pilling, color fastness to sunlight, tensile breaking rope force under low temperature environment of automotive interior textiles, its testing methods are very special, and the requirements of different manufacturers are not the same. But more general requirements, such as flame retardancy, require less than 4 inches / min.
The relevant standards of Europe and the United States are mainly as follows:
1, the United States: FMVSS302 federal vehicle safety standard 302
This standard specifies the technical requirements and test methods for the horizontal combustion characteristics of automotive interior materials, and is suitable for the evaluation of the horizontal combustion characteristics of automotive interior materials.
2. EU: combustion performance test of materials for 95-28-EC internal structure of motor vehicles (cars)
The European Union's standard combustion test method for automotive materials mainly adopts the United States Federal Automobile Safety Standard (FMVSS) and some European Union national standards. For the entire automotive industry, the combustion test method used is FMVSS 302.
In addition, the French standard NF P 92-505 (drop test) is also a small flame propagation test, similar to EN ISO 11925-2. It is used as a supplementary test method for FMVSS 302 in some automotive applications.
For example, the decoration materials for tourist buses in the European Union, in addition, the curtain materials for tourist buses must also meet ISO 6940 standards.
In particular, experts caution that manufacturers should also pay attention to VOC (Volatile Organic Compounds) release requirements, which are mandatory in the European Union. (China Textile Economic Information Network)
