20、g-Penetrant testing-Part : General principles published in 1997 without modifying the technical contents, but some parts (classification of indications and discontinuities, marking, etc.) which are not stated in the European Standard are added without modifying the contents of the former Japanese In
21、dustrial Standard. Annex A is normative and cited from the European Standard. 1 Scope This Standard 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 surface of the material in manufacturing process or
22、 in service and products to be tested (hereafter referred to as “test objects“), and specifies classification of pen- etrant indication by discontinuities. 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 the
23、y are not excessively porous. Examples of which are castings, forgings, welds, ceramics, etc. This Standard is not intended to be used for acceptance criteria and gives no in- formation relating to the suitability of individual test systems for specific applica- tions nor requirements for test equip
24、ment. The term “discontinuity“ is used here in the sense that no evaluation concerning acceptability or non-acceptability is included. Methods for determining and moni- toring the essential properties of penetrant testing products to be used are specified in JIS Z 2343-2 and JIS Z 2343-3. 2 Normativ
25、e references The following standards contain. provisions which, through reference in this Standard, constitute provisions of this Standard. If the indication of the year of coming into effect is given to these referred standards, only the edi- tion of indicated year constitutes the provision of this
26、 Standard but the revision and amendment made thereafter are not applied. The normative references without the indication of the year of coming into effect (or the year of publication) apply limiting only to the most recent edition (including the amendment).

Apply the same penetrant by any conven
36、ient means, then follow exactly the same process as initially used, up to application of the developer. After excess penetrant removal and drying of the part, apply the peelable de- veloper as recommended by the manufacturer. When the recommended development time has elapsed, carefully peel off the
37、developer coating. Indication(s) appear(s) on the face of the coating which was in direct contact with the part. c) d) 8.5.7 Development time The development time should be between 10 min and 30 min, longer times may be agreed between the contracting parties.

Immediately after drying when a wet developer is applied. 8.6 Inspection 8.6.1 General Generally, it is advisable to carry out the first examination just after the application of the developer or as soon as the developer is dry. This facili

If necessary, more favour

The use of a different type of penetrant or a penetrant of the same type from a dif- ferent supplier is not allowed unless a thorough cleaning has been carried out to remove penetrant residues remaining in the discontinuities. 9 Test report an
