This standard covers the functionality construction, interfaces, testing including pass fail criteria for draw gear and screw coupling. The standard describes three categories of classification of draw gear and screw coupling, (1 MN, 1,2 MN and 1,5 MN). 2 Normative references The following referenced documents are indispensable for the application of this document.
