The ASME Code Section I requirements are normally applied for the inspection and test plan in a manufacturing shop. The witness of some inspection and testing by third party inspectors is mandatory and cannot be waived.

Some others must only be monitored and full witnessing is not necessary; for these items, the inspection man-days etc. depend on the purchaser’s decision. Some prefer stringent monitoring and even assign a resident inspector in the manufacturing shop, and others relay to the quality control system of the manufacturer and assign only a few days for monitoring points. These are some of the inspection points that need to be witnessed, checked monitored and reviewed by a third party inspector for a water tube boiler construction.
