scope:

This Standard specifies requirements for the stainless steel pipes (hereafter referred to as pipes) used for piping for corrosion resistance, low temperature service, elevated temperature service, fire-fighting service or the like.

NOTE 1 This Standard generally applies to pipes of outside diameter 10.5 mm (nominal diameter 6A or 1/8B) to 660.4 mm (nominal diameter 650A or 26B) (see 10.1).

NOTE 2 The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 9329-4 : 1997 Seamless steel tubes for pressure purposes - Technical delivery conditions - Part 4 : Austenitic stainless steels

ISO 9330-6 : 1997 Welded steel tubes for pressure purposes - Technical delivery conditions - Part 6 : Longitudinally welded austenitic stainless steel tubes (Overall evaluation : MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standards and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
