Changes
The following changes have been made as compared to Technical Supply Specification TL 1010: 1997-05: ─ Section 3.1 expanded 1
Scope
This Technical Supply Specification defines requirements 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 pa
ssenger 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. 2

3 Requirements 3.1
Basic specifications
哈弗h2多少钱Approval of first supply and changes according to Volkswagen standard VW 01155. Avoidance of hazardous substances according to VW 91101.
Materials/components in the passenger compartment shall comply fully with the requirements spe-cif
ied in national regulations if the materials/components are intended for export to countries in which compliance with these requirements is stipulated by law. This applies in particular to 571.302 (USA.), CMVSS 302 (Canada), GB 8410 (China) and TRIAS 48-1993 (Japan).
Note regarding CB 8410 (China): The motor cover and wheel cowl components mentioned in the regulation only have to be tested if they are located within the passenger compartment. 3.2
Validity of requirements
The minimum requirements described below shall be fulfilled by all materials/components in the passenger compartment (see Section 2). If even a single value of a random sample is out of com-pliance with the requirement, this is sufficient grounds to reject the entire delivery. 3.3
Mandatory documentation
Sections of Table 1 marked with a documentation bar ( ) are subject to mandatory docu-mentation if the TL number in the drawing is also marked with a bar or if a corresponding TLD (Technical Guideline for Documentation) number appears in the drawing. The documents shall be kept on file for 10 years.

3.4 Burning behavior
See Table 1. The tests are performed on unaged material and material that has been aged accord-in
g to Test Specification PV 3904. The test results determined on unaged material are not subject to mandatory documentation. Test results on parts with a sample length of < 100 mm are also not subject to mandatory documentation. For such parts, an agreement can be reached to perform testing on sheet material whose thickness corresponds to the minimum wall thickness or thickness of the finished parts.

4 Notes on testing
4.1 Testing of burning behavior
Test equipment and method according to U.S. Regulation 571.302 and according to DIN 75200. Specimens shall be taken from the material direction with the highest burning rate. The material surface that is located closest to the air space of the passenger compartment shall face downward. Except for specimens < 51 mm in width, the use of support wires is not permitted for specimens that, when exposed to flame (in a preliminary test), deflect, roll up and exhibit irregular burning due to the fact that the burn-off is no longer horizontal.
The following applies to parts with a specimen length < 100 mm: distance between support wires 10 mm, first wire is 10 mm from the open end of the holder.
