2、l Japanese Indus- trial 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 b
3、eing attached, based on the provision of Article 12 Clause 1 of the In- dustrial Standardization Law applicable to the case of revision by the provision of Article 14. Consequently JIS G 313611994 is replaced with this Standard. This revision has been made based on ISO/DIS 24314:2005 Structizral ste
