InstallationWhat are the standards for installation for nonnuclear boiler and pressure vessels?

Where a conflict exists between the requirements of the standards listed below and this chapter, this chapter shall prevail. The duties of the in-service inspector do not include the installation's compliance with other standards and requirements (environmental, construction, electrical, undefined industrial standards, etc.), for which other regulatory agencies have authority and responsibility to oversee.
The standard for installation of nonnuclear boilers, unfired pressure vessels, and safety devices is the National Board Inspection Code (NBIC), current edition Part 1, excluding Section 5 and Section 6, Supplements 1, 2, and 5 which may be used as nonmandatory guidelines.
