Burning Behavior of
汽车内饰材料的燃烧特性
1 范围
本标准规定了对汽车内饰零件材料的燃烧特性的一般要求和试验方法。
本标准适用于零件的表面直接接触乘客室空间和距乘客室空间深度在13mm（约1/2英寸）内的单一材料或复合材料。对于结构上相互接触和整个表面不完全结合的零件，必须先去掉最靠近室内空间的件，再重新考虑厚度为13mm（见图1），直到层厚度大于13mm或总厚度达到26mm（1英寸）为止。
Automotive Interior Materials
1 Scope
This Technical Supply Specification defines requirements and test method for the burning behavior of materials / components in the passenger compartment.
It pertains to every part of a single or composite material whose surface contacts the air space of the passenger compartment and that is located within a maximum depth of 13 mm (1/2 inch) from the passenger compartment surface. For parts that are joined over less than the full surface area and that succeed each other during assembly, the depth of 13 mm shall be taken into consideration again after removal of the part closest to the passenger compartment (see Figure 1), until a layer exists that is thicker than 13 mm or an overall depth of 26 mm (1 inch) has been reached.
