VW TL 52231 ABS and PC Polymer Blends - Material Requirements

The VW PV 52231 standard, developed by the Volkswagen automobile company, describes the material requirements and defines test methods for finished parts made of ABS and PC polymer blends, such as instrument covers, dashboards, storage shelves and similar parts.

This standard defines material requirements for finished parts made from acrylonitrile-butadiene styrene (ABS) and polycarbonate (PC) polymer blends, such as instrument cluster trim panels, instrument panels, and storage compartments. During testing, a sample blended according to VW TL 52231 A standard, which is dimensionally stable under heat up to 110 degrees, is used.

The basic requirements in the VW PV 52231 standard are listed as follows:

• First supply and approval of modifications must be obtained according to VW 01155 standard
• Emission behavior should be determined according to VW 50180 standard
• Weather resistance must be provided according to VW 50185 standard
• Colorimetric evaluation should be made according to VW 50190 standard
• Must avoid hazardous substances according to VW 91101 standard
• 6 finished parts are required for full testing

The characteristic values ​​in this standard are valid for new goods. The use of reclaimed material, re-grinding or industrial products containing commercially available old material is prohibited.

When producing the same component, it is allowed to mix up to 10 percent of the ground stock from the production waste generated during the initial treatment run. This must be verified and documented.

If the component supplier and buyer have agreed on the use of recycled materials, the release test for the component should also include specific documentation of the material flow of the recycled materials. In the relevant components, the "REC" identifier must be added to the material code according to the ISO 1043-1 standard. If the percentage of recycled material used is available, this should be clearly stated.

The surface and interior of the finished parts must be free from streamlines, lines, voids, cracks and similar defects and machining defects. Pit marks at the base of ribs and reinforcements are only permitted if they do not adversely affect the function, appearance of the parts or assembly, Finished parts should allow trouble-free installation.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides testing services for ABS and PC polymer mixture materials within the scope of VW PV 52231 standard, with its trained and expert staff and advanced technological equipment.
