    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

    31、e for this document is ISO/TC 44, Welding and allied processes, Subcommittee SC 5, Testing and inspection of welds.This second edition cancels and replaces the first edition (ISO 17643:2005), which has been technically revised.4 EN ISO 17643:2015 (E) DIN EN ISO 17643:2015-121 ScopeThis International

    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,

    35、 are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

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

    46、ent used for eddy current testing in accordance with this International Standard shall be capable of analysis and display in the complex plane. The amplitude and phase of eddy current signals shall be measurable.6.4.1.2 FrequencyThe eddy current instrumentation shall be able to operate at a selected

    47、 frequency within the range 1 kHz to 1 MHz.6.4.1.3 Signal displayThe display shall include the facility to freeze eddy current signals on screen until reset by the operator. The trace shall be clearly visible under all lighting conditions expected during testing.6.4.1.4 Phase controlThe phase contro

    48、l shall be able to give complete rotation of displayed signals (360 ) in steps of no more than 10 each.6.4.2 Surface probes6.4.2.1 Probes for measuring coating thickness and material evaluation relative to calibration blockThe probe shall operate in the absolute mode at a selected frequency in the r

    49、ange from 1 kHz to 1 MHz. All the probes shall be clearly marked with their operating frequency range.6.4.2.2 Probes for testing of weldsFor testing of ferritic welds, probes specially designed for this purpose shall be used.The coils assembly shall be orthogonal, tangential or equivalent.The electrical connection shall enable differential measurements which are characterized by having a minimal dependency on continuous or small variations in conductivity, permeability and lift-off in
