MS 2399:2011现行

This Malaysian Standard specifies techniques for detection of surface and sub-surface imperfections in welds of ferromagnetic materials, including the heat affected zones, by means of magnetic particle testing. Variations in the basic techniques that will provide a higher or lower test sensitivity. are described in Annex A (to see the applicability as most of the text is already included as part of the main text). This standard does not specify acceptance levels of the indications. Information on acceptance levels for indications may be found in product or application standards. This method is not applicable to weldment formed between ferromagnetic and non ferromagnetic materials e.g weldment joining carbon steel and austenitic stainless steel; or weldment made of non-ferromagnetic filler metal e.g. welding of 9% Ni steel. This standard does not apply to the residual magnetisation technique.
