The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has
30、been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical st

In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accor

36、title Destructive tests on welds in metallic materials Hot cracking tests for weldments Arc welding processes : Part 1: General Part 2: Self-restraint tests Part 3: Externally loaded tests Technical ReportDIN EN ISO 17641-2:2016-03 EN ISO 17641-2:2015 (E) 4 1 ScopeThis part of ISO 17641 specifies th
37、e required specimens, the test piece dimensions, and the procedures to be followed to carry out self-restraint hot cracking tests.The following tests are described: T-joint weld cracking test; weld metal tensile test; longitudinal bend test.The tests are designed to provide information about the hot
38、 cracking sensitivity of weld metals. The tests are not suitable for the assessment of parent materials.This part of ISO 17641 applies primarily to fully austenitic stainless steels, nickel, nickel base, and nickel copper weld metals. This part of ISO 17641 can also be used for other weld metals.Thi
39、s part of ISO 17641 describes only how to carry out the tests and report the results. It does not give any acceptance criteria.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

These test methods are described in Table
48、 2.In all cases, the cracks are generated during the welding of the test pieces. The tensile test and longitudinal bend test are subjected to additional straining which does not generate any new cracks, but widens the cracks formed during the welding which enables them to be more easily detected and measured.DIN EN ISO 17641-2:2016-03 EN ISO 17641-2:2015 (E) 6
