ASME BPVC 。Ⅸ-2017 QW-200.2 (f) Multiple WPSs WithOne PQR or Multiple PQRs With OneWPS. Several WPSs maybe prepared from the data on a single PQR (e.g., a 1Gplate PQR may support WPSs for the F, V, H, and Opositions on plate or pipe within all other essentialvariables) . A single WPS may cover several sets of essentialvariable ranges as long as a supporting PQR exists for eachessential and, when required, supplementary essential variable[e.g., a single WPS may cover a thickness range from1/16 in. (1.5 mm) through 11/4 in. (3 2 mm) if PQRs existfor both the 1/1 6 in. (1 .5 mm) through 3/1 6 in. (5 mm)and 3/1 6 in. (5 mm) through 11/4 in. (32 mm)thickness ranges] .
PQR与WPS是多对多的关系,可以按楼主的方法做
