scope:
This Standard specifies requirements for the hot-rolled steel plates of 780 N/mm2 in tensile strength and 685 N/mm2 in proof stress with excellent weldability (hereafter referred to as steel plates) used for bridge, pressure vessels, high pressure equipment and other structures.
NOTE The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.
ISO 4950-1 : 1995 High yield strength flat steel products - Part 1 : General requirements
ISO 4950-2 : 1995 High yield strength flat steel products - Part 2 : Products supplied in the normalized or controlled rolled condition
ISO 4950-3 : 1995 High yield strength flat steel products - Part 3 : Products supplied in the heat-treated (quenched + tempered) condition (overall evaluation : MOD)
In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
