16、 (the International 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 com

17、mittee 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 closely with the International Electrotechnical Commission (IEC) on all matters of electrot

18、echnical standardization. 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 mem

19、ber bodies for 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 identify

20、ing any or all such patent rights. ISO 3452-5 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 138, Non-destructive testing, in collaboration with ISO Technical Committee TC 135, Non-destructive testing, Subcommittee SC 2, Surface methods, in accordance wit

23、ion Temperatures higher than 50 C can affect the properties of penetrant test materials. The use of penetrant materials and the testing of penetrant materials within the temperature range 10 C to 50 C are the subject of EN 571-1 and ISO 3452-2. This part of ISO 3452 addresses materials and their use

24、 at higher temperatures. This part of ISO 3452 introduces the concept of process times being linked to working temperatures and accordingly users are recommended to ensure that testing products are correctly associated with process parameters in written instructions (procedures). Testing products ma

25、y be specifically developed and qualified for high temperature use but testing products qualified for use at normal temperatures, in some cases, may also be suitable for higher temperature use. This part of ISO 3452 was prepared with the assistance of ISPESL (Italy), whose laboratory performed resea

26、rch activity to verify the possibility of using penetrant at temperatures higher than 50 C, up to 200 C.

32、4 High temperature penetrant testing requirements Penetrant materials shall be qualified, type tested for the temperature range within which the test temperature is included. The general principles as defined in ISO 3452-1 shall apply unless otherwise stated in this part of ISO 3452 or in the manufa

33、cturers instructions. The manufacturers instructions shall be followed. 5 Safety precautions Equipment and testing products shall be handled, stored and used in a safe manner and always in accordance with the manufacturers instructions. The viewing conditions required in this part of ISO 3452 are th

34、e same as those for the 10 C up to 50 C temperature range and the same safety precautions should be observed. In addition to the safety considerations associated with 10 C up to 50 C temperature range, due consideration shall be given to the risks associated with use at higher temperatures. Skin-bur

35、ning, flammability and volatility are examples of potential hazards which vary with temperature. The work area shall always be adequately ventilated and personnel exposure levels should be carefully assessed. All relevant European, national and local regulations pertaining to health and safety, envi

36、ronmental requirements etc. shall be observed. 6 Personnel qualification Personnel carrying out testing in accordance with this part of ISO 3452 shall be suitably certified (e.g. ISO 9712, EN 473). They shall also be knowledgeable of the special considerations for testing at higher temperatures (e.g

37、. time limitations for inspection, special considerations of materials). 7 Classification of testing products Testing products shall be classified by type, method and form as given in ISO 3452-2:2006, Table 1, but high temperature sensitivity shall be as described herein. Products also classified an

38、d qualified for 10 C up to 50 C temperature range may be designated with a suffix to show suitability for use at temperatures above 50 C, e.g. Type I, Method C, Form a, Level 2, Temperature M, (ICa-2/M). 8 General characteristics of the products The reference products as stated in 14.2 are penetrant

39、 materials used in the range 10 C to 50 C for comparison purposes (see 14.3) and they shall conform with the requirements of ISO 3452-2. Thermal stability shall be stated by the manufacturer and the test shall be carried out at least at 20 C above the maximum rated working temperature for the candid

40、ate testing material. Testing products shall be selected according to application with appropriate reference to the manufacturers recommendations for process parameters.

41、:2008(E) ISO 2008 All rights reserved 39 Reference blocks Temperature designation shall be performed with defined reference blocks (see e.g. Annex A of this part of ISO 3452 or ISO 3452-3, Type 1). Before use, reference blocks shall be cleaned using suitable means and tested for absence of indicatio

42、ns with a suitable non-aqueous wet developer. Absence of indications confirms that the panel is suitable for use. The developer shall be removed and the panel shall not be touched by bare hands throughout the process (to avoid contamination). Clean, white cotton, or other materials meant for tempera

43、ture-rating gloves, may be used to assist with handling. Annex A comparators shall be used only once and in matched pairs. One of them shall be tested at the temperature given in Clause 12 and the other one shall be tested at ambient temperature using penetrant materials suitable for use at 10 C to

44、50 C, (see Clause 8). NOTE High temperature process of Type 1 panels could lead to some residues being difficult to remove from the cracks. Specific care needs to be taken to maintain the usability of the panels. 10 Equipment Testing at higher temperatures requires additional equipment to that detai

45、led in ISO 3452-2, specifically, a) a thermostatic cell: capable of achieving a stable temperature at least 50 C above the maximum testing temperature, b) gloves suitable for that temperature, c) a brush suitable for that temperature, and d) a surface thermometer (contact type): 5 C error of indicat

46、ion of a measuring instrument. 11 Viewing conditions Viewing conditions shall comply with the requirements of ISO 3059. 12 Test temperature Temperature ratings and test points are shown in Table 1. For materials with a working temperature range of more than 50 C, testing shall be carried out at maxi

47、mum intervals of 50 C. Testing shall be carried out at the temperatures shown in Table 1.
