gives full details of methods 1 and 2 and includes a method 3 as compared to the previous editions BS 684-1
The contents of PD ISO/IEC TR 20000-3 contain:
These test methods are intended to provide a means of characterizing synchronous belt properties for belts which are evaluated and qualified by dynamic laboratory and field testing
The method is applicable to powders made up of particles having the same density and of comparable shape
