the reference for Section VIII comes from B31.3 Table 341.3.2 where it tells you to use Section VIII Div 1 appendix 4 for size and distribution acceptance limits for porosity.
Gerald, thanks. It is true you need BPV's with the PP's. Gotta have VIII. Gotta have IX. Gotta have the II's. Gotta have V. And if your doing 31.1 ya gotta have I.
