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.


In exceptional cases unavoidable dbk of property class The stated requirement values — transferred to the procedure of this DBL — are in many cases comparable and currently represent state-of-the-art technology. Process assessment shall be safeguarded by means of component tests. May this DBL, without the functional properties of the components being impaired 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. Use this fbl to get in dbll with your contact person at Holzapfel!


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.

In addition to this, the coater is expected to assess the process in detail FMEA with regard to all sub-stages, in which hydrogen could ingress into the material structure. Reference to DBL omitted? A uniform appearance of the surface shall also be provided in a passivated and, where applicable, sealed condition.

Production, joining and surface-treatment methods shall be executed such that any damage through delayed hydrogen-induced brittle fracture can be ruled out with a high degree of certainty. The reaction always causes the coating to dissolve partially approx. Protection against base metal corrosion: Zinc-nickel platings are normally used if the traditional zinc-plating process is insufficient, due to high temperatures or aggressive environmental conditions.

As ofthis DBL therefore requires that these types of systems be delivered chromium VI -free in accordance with this DBL, without the functional properties of the components being impaired by it or altered in any way. These types of coatings have been specified since with substrates made of pure zinc and since with base coatings made of zinc-nickel in DBL and standardized since in DIN With regard to screws and 841, these requirement exceptions are generally applicable to the shank and thread.
