ASTM WK87725

Revision of A53/A53M-22 Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless


In an inquiry it was noted that Figure 1 and corresponding Table 3 have differing terminology. VIO and NIO are in Figure 1. V1O and N1O are cited in Table 3. This Work Item will address the apparent discrepancy between them that has been in place since 1999 when both were added to the Specification.
