25、ional 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 bee
26、n 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 stand
27、ardization.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. This document was drafted in accordan
28、ce 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 or all such patent rights. Details of
29、 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 and does not constitute an endorsem

32、 Standard defines eddy current testing techniques for detection of surface breaking and near surface planar discontinuities, mainly in ferritic materials (weld material, heat-affected zones, base material).Eddy current testing can also be specified for use with non-ferritic materials, for example in
33、 an application standard.The techniques can be applied to coated and uncoated objects during fabrication and in service, both onshore and offshore.Eddy current testing can be carried out on all accessible surfaces and on welds of almost any configuration.Unless otherwise specified at specific items
34、in this International Standard, the general principles of ISO 15549 apply.NOTE Eddy current testing is usually performed in the as-welded condition. However, the accuracy of the results can be affected by very rough surface finishes.2 Normative referencesThe following documents, in whole or in part,

It is recommended that personnel are qualified in accordance with ISO 9712 or an equivalent standard at an appropriate level in the relevant indus

Otherwise, the procedures detailed in this International Standard shall be followed.6 General applications6.1 Essential variablesPrior
40、to eddy current testing, the following essential items shall be specified in accordance with ISO 15549: certification of testing personnel; testing plan; testing equipment; calibration of the equipment; calibration blocks; acceptance criteria; recording of indications; reporting format; actions nece
41、ssary for non-acceptable indications.6.2 Additional informationPrior to eddy current testing, the following information should be specified. Further information may be necessary for determination of the nature of the discontinuities and the composition or grade of the base material: type of filler m
42、etal; location and extent of welds to be tested; weld surface geometry; surface conditions; coating type and thickness.6.3 Surface conditionsEddy current testing can be used to detect surface cracks through non-metallic coatings up to a thickness of 2 mm. For coating thicknesses greater than 2 mm, t
43、he sensitivity of the test method shall be demonstrated in advance before eddy current testing is used.NOTE 1 Eddy current testing is dependent on close contact between the probe and the test surface. For effective eddy current testing of welds, it should be noted that local adverse weld form, exces
44、sive weld spatter, scale, rust and loose paint can influence sensitivity by separating the probe from the test object and by inducing noisy responses.NOTE 2 It should be noted that some types of conductive coating, such as thermally sprayed aluminium and lead, can seriously influence the results as
45、they can deposit electrically conductive metallic material in cracks open to the surface. Cracks covered with such a metallic deposit are not always indicated by this method.6 EN ISO 17643:2015 (E) DIN EN ISO 17643:2015-126.4 Equipment6.4.1 Instrumentation (excluding probe)6.4.1.1 GeneralThe instrum
