3、teel Federation (J1SF)with a draft being attached, based on the provision of Article 12 Clause 1 of the Industrial Standardization Law. Consequently JIS G 3507:1991 is replaced with this Standard. Attention is drawn to the possibility that some parts of this Standard may con- flict with a patent rig

Portions given sidelines or dotted underlines are the matters modified from the original International Standard. A list of modifications with
14、the explanations is given in annex 2 (informative). 1 This part of JIS G 3507 specifies the carbon steel wire rods, (hereafter re- ferred to as the “wire rods”) to be used mainly for the manufacture of carbon steel wires by cold heading and cold forging. Scope Remarks The International Standards cor
15、responding to this part of JIS G 3507 is as follows. 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.
