This European Standard EN 13480 for metallic industrial piping consists of eight interdependent and not dissociable Parts which are: Part 1

15、: General; Part 2: Materials; Part 3: Design and calculation; Part 4: Fabrication and installation; Part 5: Inspection and testing; Part 6: Additional requirements for buried piping; CEN/TR 13480-7, Guidance on the use of conformity assessment procedures; Part 8: Additional requirements for aluminiu

16、m and aluminium alloy piping. Although these Parts may be obtained separately, it should be recognised that the Parts are interdependent. As such the manufacture of metallic industrial piping requires the application of all the relevant Parts in order for the requirements of the Standard to be satis

17、factorily fulfilled. This European Standard will be maintained by a Maintenance MHD working group whose scope of working is limited to corrections and interpretations related to EN 13480. questions can be downloaded from the link to the MHD website.
