2 NORSOK standards are administered byNTS (Norwegian Technology Standards Institution).The purpose of this industry STANDARD is to replace the individual oil company specifications for usein existing and future petroleum industry developments, subject to the individual company's reviewand NORSOK standards make extensive references to international standards. Where relevant, thecontents of this STANDARD will be used to provide input to the international standardisation to implementation into international standards, this NORSOK STANDARD will be revision replace NORSOK STANDARD M-CR-630, rev. 1, and the changes from rev.

3 1 to rev. 2are mainly: more precise test requirements in some cases, increased extent of NDT The acceptance criteria have not been changed. MINOR DEVIATIONS FROM ASME CODE REQUIREMENTS The use of the piping materials according to NORSOK Standards (L-CR-001, M-630 and M-601)will result in some minor deviations from the ASME code. All deviations have been carefullyconsidered, and they are in line with Norwegian and European practice. The deviations are: NORSOK have of practical reasons limited the thickness for requiring impact testing to 6 mm If subsize Charpy V-notch impact test specimens are used, the energy requirement is increasedinstead of lowering the test temperature.

4 Impact testing is not required in the qualification of the welding procedures for weldments inaustenitic stainless steel when used in the temperature range from 29 C to 105 C. Eddy current examination is accepted as replacement for spot radiography of stainless steel weldsfor wall thicknesses less than mm. Thin walled (thickness up to 7 mm) longitudinal welded pipes in 6 Mo austenitic stainless isaccepted in as welded condition provided the plate material used is solution general, the MDS have supplementary requirement beyond the ASTM STANDARD to ensure a propersafety Data Sheets for PipingM-630 Rev.
