DIN 946

Determination of coefficient of friction of bolt/nut assemblies under specified conditions

English 1991

DIN
Detailed Information

This standard specifies a tightening test for determining the coefficient of friction of bolt/nut assemblies under specified conditions. It is only applicable for comparison purposes, such as a comparison of assemblies with different surface finishes or for cases where different lubricants are used.

Given the variety of boundary conditions in service (e.g. resilience of bolted components, finish of washers), the results of testing in accordance with this standard do not permit conclusions to be drawn as to the behaviour of bolt/nut assemblies in a particular application, e.g. where such assemblies form part of structural configurations.
