2 Properties

Parts manufactured from thermoplastics with

- low specific surface loads and low sliding speeds for bearing elements

- control surfaces with high visual impact

- impact resistant (dry impact resistant) modification for easy-to-install quick-release systems which can be detached several times.

The supply parts shall comply with the requirements of DBL 8585 "Negative Substance List for the Selection of Mate-rials".

The availability of a certificate of testing in accordance with the following method is specified as an overriding re-quirement for adherence to the emission values for interior trim materials: VDA 278; threshold values DBL 8585. The user is responsible for checking whether the version in his possession is the latest version. In particular in the case of substances listed in DBL 8585 Section 2.3, the supplier is required to continuously minimize the concentra-tion and emission at least in accordance with the state of the art, even when values have fallen below the required DBL threshold values.
