在 ASTM 官方网站上查到 ASTM A480 / A480M 的最新版本是 14b:
ASTM A480 / A480M - 14b
Standard Specification for General Requirements for Flat-Rolled Stainless and Heat-Resisting Steel Plate, Sheet, and Strip
An ASTM designation number identifies a unique version of an ASTM standard.
A480 / A480M - 14b
A = ferrous metals;
480 = assigned sequential number
M = SI units
14 = year of original adoption (or, in the case of revision, the year of last revision)
b = indicates subsequent revision in same year

14b,14a,14,13b,13a,13,12,11b,11a,11,10a,10,09b,09a,09,08b,08a,08,06b,06a,06,05,04a,04,o3c,03b,03a,03,02,01b,01a,01,00.
由此可以看出 ASTM A480 / A480M 修改频繁,几乎每年要修改两三次。
在 2013 版 ASME BPVC Section II, Part A 中,SA-480/SA-480M SPECIFICATION FOR GENERAL REQUIREMENTS FOR FLAT-ROLLED STAINLESS AND HEAT-RESISTING STEEL PLATE, SHEET, AND STRIP (Identical with ASTM Specification A480/A480M-11a.)
所以,你做 ASME BPVC,只需要用 ASTM Specification A480/A480M-11a 就可以了。
