J IS JAPANESE INDUSTRIAL STANDARD Translated and Published by Japanese Standards Association Carbon steel pipes for high pressure service ICs 23.040.10; 77.140.75 Reference number : JIS G 3455 : 2005 (E) PROTECTED BY COPYRIGHT 14 S G 3455 : 2005 Foreword 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 to the case of revision by the provision of Article 14. Consequently JIS G 3455 : 1988 is replaced with this Standard. This revision has been made based on IS0 9329-2 : 1997 Seamless steel tubes for pressure purposes-Technical delivery conditions-Part 2: Unalloyed and alloyed steels with specified elevated temperature properties for the purposes of making it easier to compare this Standard with International Standard; to prepare Japanese Industrial Standard conforming with International Standard; and to propose a draft of an International Standard which is based on Japanese Industrial Standard. Attention is drawn to the possibility that some parts of this Standard may conflict with a patent right, application for a patent after opening to the public, utility model right or application for registration of utility model after opening to the public which have technical properties. The relevant Minister and the Japanese Industrial Standards Committee are not responsible for identifying the patent right, application for a patent after opening to the public, utility model right or application for registration of utility model after opening to the public which have the said technical properties.
