Unless otherwise agreed, the tests are carried out at room temperature. However, tests
35、carried out under standard conditions are made at a temperature of 10 C to 35 C. This method allows determination of the tightening characteristics of threaded fasteners and related parts. 2 Normative references The following referenced documents are indispensable for the application of this documen
