Although the End-of-Life Vehicle Act does not currently apply to heavy-duty trucks or buses, for reasons of variant reduction in new designs, consideration should be given to also specifying Cr VI free surfaces for commercial vehicle parts. The ideal heat treatment s used for a part temperature, duration, operating sequence shall be ascertained and stated in the ISIR initial sample inspection report.

As ofit is therefore necessary for these types of systems to be delivered chromium VI -free in accordance with this DBL, without the functional properties of the components being impaired by dnl or altered in any way.

Steel and powdered metals are the metals most usually plated. Page 9 DBL Pure zinc coatings, and high-alloy zinc-alloy coatings ZnNi are used for metallic base coatings. Before commencement of production deliveries, the coater shall determine and record the complete pre-treatment and coating process, the physical data treatment periods, temperatures 845 the composition of all process chemicals, and, if required, optimize them.

The resulting measures shall be specified by the coater. Otherwise the use of fast-to-handle lubricants for threaded parts shall be examined. Vogel Stuttgart Department: No chipping and blistering of the coat is allowed. A sufficient number of in-process preloading tests on suitable hydrogen sensitive samples shall be used as the basis for establishing the suitability of the process for coating critical components.

For this reason, alongside the corrosion protection, attention shall also be paid to any possible changes in surface-specific functional properties in comparison to coatings containing Cr VI. While chromating is produced from solutions containing Cr VI and the chromating on the workpiece may therefore also contain Cr VIthe term passivation refers to chromium VI -free corrosion protection.
