20、tional 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 which a technical committee has be
21、en 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 stan
22、dardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for
23、voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.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 or all s
24、uch patent rights.ISO 13588 was prepared by the European Committee for Standardization (CEN) in collaboration with ISO Technical Committee TC 44, Welding and allied processes, Subcommittee SC 5, Testing and inspection of welds, in accordance with the Agreement on technical cooperation between ISO an
25、d CEN (Vienna Agreement).Requests for official interpretations of any aspect of this International Standard should be directed to the Secretariat of ISO/TC 44/SC 5 via your national standards body.

26、O 13588:2012INTERNATIONAL STANDARD ISO 13588:2012(E)Non-destructive testing of welds Ultrasonic testing Use of automated phased array technology1 ScopeThis International Standard specifies the application of the phased array technology for the semi- or fully automated ultrasonic testing of fusion-we
27、lded joints in metallic materials of minimum thickness 6 mm. It applies to full penetration welded joints of simple geometry in plates, pipes, and vessels, where both the weld and parent material are low-alloyed carbon steel.Where material-dependent ultrasonic parameters are specified in this Intern
28、ational Standard, they are based on steels having an ultrasonic sound velocity of (5 920 50) m/s for longitudinal waves, and (3 255 30) m/s for transverse waves. It is necessary to take this fact into account when examining materials with a different velocity.This International Standard provides gui
29、dance on the specific capabilities and limitations of phased array technology for the detection, location, sizing and characterization of discontinuities in fusion-welded joints. Phased array technology can be used as a stand-alone technology or in combination with other non-destructive testing (NDT
30、) methods or techniques, for manufacturing inspection, pre-service and for in-service inspection.This International Standard specifies four testing levels, each corresponding to a different probability of detection of imperfections.This International Standard permits assessment of indications for ac
31、ceptance purposes based on either amplitude (equivalent reflector size) and length or height and length.This International Standard does not include acceptance levels for discontinuities.This International Standard is not applicable: for coarse-grained metals and austenitic welds; for automated test

40、ents for welded joints are mainly associated with the material, welding process and service conditions. To accommodate all of these requirements, this International Standard specifies four testing levels (A, B, C, and D).From testing level A to testing level C, an increasing probability of detection
41、 is achieved by an increasing testing coverage, e.g. number of incidences, combining techniques.Testing level D may be agreed for special application using a written procedure which shall take into account the general requirements of this International Standard. This includes tests of metals other t
42、han ferritic steel, tests on partial penetration welds, tests with automated equipment, tests at object temperatures outside the range.In general, the testing levels are related to quality levels (e.g. ISO 58172). The appropriate testing level can be specified by standards for testing of welds (e.g.
43、 ISO 17635), product standards or other documents. When ISO 17635 is specified, the recommended testing levels are as given in Table 1.2 ISO 2012 All rights reservedBS EN ISO 13588:2012ISO 13588:2012(E)Table 1 Recommended testing levelsTesting level Quality level in ISO 58172A C, DB BC by agreementD
44、 special applicationTable 2 shows the minimum requirements and in all cases as described in 7.2 the set-up shall be verified with a reference block. In cases where scanning is from one face (excluding TOFD), half and full skip shall be used and stored; if scanning is performed from both faces, half
45、skip is sufficient.If the evaluation of the indications is based on amplitude only, the deviation from the normal to the weld shall not exceed 6.Table 2 Description of testing levelsModeTesting levelsExample of sketchesA B CReference block (see Annex A)Block A Block B Block CTest set-upFixed angles
