The work of preparing International Standards is normally carried out through ISO tec
24、hnical 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, also take part in the work. ISO collaborates closel
25、y with the International Electrotechnical Commission (IEC) on all 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 nee
26、ded for the different types of ISO documents should be noted.

33、 3452-1:2013INTERNATIONAL STANDARD ISO 3452-1:2013(E)Non-destructive testing Penetrant testing Part 1: General principles1 ScopeThis part of ISO 3452 specifies a method of penetrant testing used to detect discontinuities, e.g. cracks, laps, folds, porosity and lack of fusion, which are open to the s
34、urface of the material to be tested. It is mainly applied to metallic materials, but can also be performed on other materials, provided that they are inert to the test media and not excessively porous (castings, forgings, welds, ceramics, etc.)It also includes requirements for process and control te
35、sting, but is not intended to be used for acceptance criteria and gives neither information relating to the suitability of individual test systems for specific applications nor requirements for test equipment.NOTE 1 Methods for determining and monitoring the essential properties of penetrant testing
36、 products to be used are specified in ISO 3452-2 and ISO 3452-3.NOTE 2 The term discontinuity is used in this part of ISO 3452 in the sense that no evaluation concerning acceptability or non-acceptability is included.2 Normative referencesThe following documents, in whole or in part, are normatively

40、ionsFor the purposes of this document, the terms and definitions given in ISO 12706 apply.4 Safety precautionsAs penetrant inspection techniques often require the use of harmful, flammable and/or volatile materials, certain precautions shall be taken.

41、013ISO 3452-1:2013(E)Prolonged or repeated contact of these materials with the skin or any mucous membrane should be avoided. Working areas shall be adequately ventilated and sited away from sources of heat, sparks or naked flames in accordance with local regulations.The penetrant testing products a
42、nd equipment shall be used with care and always in compliance with the instructions supplied by the manufacturer.When using filtered UV-A sources, care shall be taken to ensure that unfiltered radiation from the UV-A source does not directly reach the eyes of the operators. Whether it forms an integ
43、ral part of the lamp or is a separate component, the UV-A filter shall always be maintained in good condition.In addition to the need to follow legislation (e.g. Directive 2006/25/EC), care shall be taken to ensure the safe implementation of the method.5 General principles5.1 PersonnelTesting shall
44、be carried out by proficient, suitably trained and qualified personnel and, where applicable, shall be supervised by competent personnel nominated by the employer or, by delegation of the employer, the inspection company in charge of testing. To demonstrate appropriate qualification it is recommende
45、d that personnel be certified according to ISO 9712 or an equivalent formalized system. Operating authorization for qualified persons shall be issued by the employer in accordance with a written procedure. Non-destructive testing (NDT) operations, unless otherwise agreed, shall be authorized by a co
46、mpetent and qualified NDT supervisory individual (Level 3 or equivalent) approved by the employer.5.2 Description of the methodPrior to penetrant testing the surface to be inspected shall be cleaned and dried. Suitable penetrants are then applied to the test area and enter into discontinuities open
47、to the surface. After the appropriate penetration time has elapsed the excess penetrant is removed from the surface and the developer applied. The developer absorbs the penetrant that has entered and remains in the discontinuities and may give a clearly visible enhanced indication of the discontinui
48、ty.Should complementary NDT be required, the penetrant inspection shall be performed first, unless otherwise agreed upon between the contracting parties, so as not to introduce contaminants into open discontinuities. If penetrant inspection is used following another NDT technique, the surface shall
49、be cleaned carefully to remove contaminants before application.5.3 Process sequenceTesting generally proceeds through the following stages:a) preparation and precleaning (see 8.2);b) application of penetrant (see 8.4);c) excess penetrant removal (see 8.5);d) application of developer (see 8.6);e) inspection (see 8.7);f) recording (see 8.7.4);g) postcleaning (see 8.8.1).See Annex A.2 ISO 2013 All rights reservedBS EN ISO 3452-1:2013ISO 3452-1:2013(E)5.4 EquipmentThe equipment used for carrying out penetrant
