10、esent through the revision in 1991. In order to be reflected technical change and change of demands on and after the last revision, the standard comes to this revision. Though study is advanced in order to conform to International Standard, Interna- tional standard (IS0 683-13) as the object is deci
11、ded to be annulled at TC17/SC4 in June, 1996, and newly revised into two standards of flat product and long prod- uct, however, they are not yet agreed upon, Therefore, this revision is advanced considering that the object International Standard does not exist. Dimensional tolerances have preliminar
12、ily conformed to International standard (IS0 R 286, IS0 System of Limits and Fits). Principal revised points are as follows. a) Grades and symbols SUS303Cu and SUS316F are added to obtain 28 grades as total by request from domestic customers. b) Dimensional tolerances Tolerances on extraction of rou
13、nd bars are changed from classes 11 to 13 to clauses 9 to 11. Further, classes 14 to 18 are added to dimensional tolerances on flat bars. c) Item for report is newly established. 1 This Japanese Industrial Standard specifies cold finished stainless steel bars (round bars, square bars, hexagonal bars
14、, and flat bars, hereafter generically referred to as “bars”). Scope 2 Normative references The following standards contain provisions which, through reference in this Standard, constitute provisions of this Standard.
