19、635:2016(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for

20、 which a technical committee has 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 a

21、ll matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. T

22、his document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any o

23、r all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users

Notably, it has

26、 been changed as follows: International Standards have replaced European standards as normative references; “examined” has been replaced by “tested” in the whole document; important modifications have been made to Annex A, Rules and standards to be applied; Annex C, Non-acceptable indications, has b

28、NTERNATIONAL STANDARD ISO 17635:2016(E)Non-destructive testing of welds General rules for metallic materials1 ScopeThis document gives guidelines for the choice of non-destructive testing (NDT) methods for welds and evaluation of the results for quality control purposes, based on quality requirement

29、s, material, weld thickness, welding process and extent of testing.This document also specifies general rules and standards to be applied to the different types of testing, for either the methodology or the acceptance levels for metallic materials.Acceptance levels cannot be a direct interpretation

30、of the quality levels defined in ISO 5817 or ISO 10042. They are linked to the overall quality of the produced batch of welds.Requirements for acceptance levels for NDT comply with quality levels stated in ISO 5817 or ISO 10042 (moderate, intermediate, stringent) only on a general basis and not in d

31、etail for each indication.Annex A gives correlations between quality, NDT and acceptance level standards.Annex B gives an overview of the standards linked to quality levels, acceptance levels and NDT methods.2 Normative referencesThe following documents are referred to in the text in such a way that
