The work of preparing Internationa
18、l Standards is normally carried out through ISO technical committees. Each member body interested in a subject for 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,
19、also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committ
20、ees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possi
21、bility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 9016 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 5, Testing and inspection of we

24、ies mainly the method to be used when describing test specimen location and notch orientation for the testing and reporting of impact tests on welded butt joints.This International Standard applies to impact tests on metallic materials in all forms of product made by any fusion welding process.It is
25、 used in addition to ISO 148 (all parts) and includes test specimen denomination and additional reporting requirements.2 Normative referenceThe following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated ref
26、erences, the latest edition of the referenced document (including any amendments) applies.ISO 148-1, Metallic materials Charpy pendulum impact test Part 1: Test method3 PrincipleImpact testing shall be in accordance with ISO 148-1. The test temperature, location, type and size of test specimen, and
27、notch orientation shall be in accordance with the relevant application standard.In addition to the requirements of ISO 148-1, the notch position may be located by macroetching.4 Method of denomination4.1 Lettering systemThe denomination is based on a lettering system to describe the type, location a
28、nd notch orientation and a numbering system to show the distance (in millimetres) of the notch from reference lines (RL). The method of denomination is shown in Tables 1 and 2. The test specimen shall be taken from the welded joint such that its longitudinal axes are at right angles to the weld leng
29、th.4.2 CharactersThe denomination comprises the following characters: 1st character U: Charpy U- notch.V: Charpy V-notch. 2nd character W: notch in the weld metal; the reference line is the centre line of the weld at the position of the test specimen.H: notch in the heat affected zone; the reference
30、 line is the fusion or the joint line (notch will include HAZ). ISO 2012 All rights reserved 1BS EN ISO 9016:2012ISO 9016:2012(E) 3rd character S: notched face parallel to the surface.NOTE This orientation is equivalent to the denomination “surface notch” used in frac-ture mechanics testing.T: notch
31、 through the thickness. 4th character a: the distance of the centre of the notch from the reference line (if a is at the centre line of the weld, a = 0 which should be recorded). 5th character b: the distance from the weld joint face side to the nearer face of the test specimen (if b is at the surfa
32、ce of the weld, b = 0 which should be recorded).NOTE In the case of double V, K or similar welds, the face side is the side that contains the larger width of the weld or from which the welding energy was first applied.4.3 Additional informationIn cases where this simple denomination does not suffici
33、ently define the location or notch orientation, a sketch referring to the weld procedure should be provided.5 Examples of denominationExamples of denomination are given in Tables 1 and 2 and Figure 1.Table 1 Notched face parallel to the surface of the test piece (S position)DenominationCentre of the
