International Standardization

Work on the Technical Specification for Determining the Scuffing Load Capacity of Bevel and Hypoid Gears and Example Calculations Finished.
Revision of ISO 4156 Parts 1 to 3 completed - 2021 edition about to be published.
On 18 March 2019, the joint plenary meeting of the ISO/TC 60 "Gears" and its Subcommittees SC 1 and SC 2 took place in Senlis (France).
New edition of the basic standards concerning the calculation of load capacity of spur and helical gears (ISO 6336-1, -2, -3 and -6) available.
The revision of ISO 4156 series has started with a Kick-off Meeting taken place on 15. and 16. April 2019 in Frankfurt.

National Standardization

VDMA position paper on the classification of gearboxess and geared motors under the Machinery Directive revised.
The member companies of the VDMA use chromium trioxide (chromium VI) especially in the field of functional hard chrome plating or decorative chrome plating. Chromium VI is subject to approval by the EU chemicals regulation REACH. The approval procedure for functional hard chrome plating has now been completed after four years.
