This translation has been made based on the original Japanese Industrial Standard revised by the Minister of Economy, Trade and Industry through deliberations at the Japanese Industrial Standards Committee, as the result

of proposal for revision of Japanese Industrial Standard submitted by The Japan Iron and Steel Federation (JISF) with the draft being attached, based

on the provision of Article 12 Clause 1 of the Industrial Standardization Law applicable t o the case of revision by the provision of Article 14

Consequently JIS G 3454 : 1988 is replaced with this Standard

This revision has been made based on I S 0 9330-1 : 1990 Welded steel tubes for pressure purposes-Technical delivery conditions-Part 1: Unalloyed steel tubes w i t h specified room temperature properties and I S 0 9329-1 : 1989

Seamless steel tubes for pressure purposes-Technical delivery conditions- Part 1: Unalloyed steels with specified room temperature properties for the purposes of making it easier t o compare this Standard with International Standards; to prepare Japanese Industrial Standard conforming with International Standards; and t o propose a draft of an International Standard which is based on Japanese Industrial Standard

Attention is drawn t o the possibility that some parts of this Standard may conflict with a patent right, application for a patent after opening t o the public, utility model right o r application for registration of utility model after opening t o the public which have technical properties The relevant Minister and t h e Japanese Industrial Standards Committee a r e not responsible for identifying the patent right, application for a patent after opening t o the public, utility model right or application for registration of utility model after opening t o the public which have the said technical properties
