Final answer:
Inspections as per B31.3 relate to the functions performed to ensure piping systems comply with the code's requirements for materials, design, fabrication, and testing to maintain quality and safety.
Step-by-step explanation:
The question refers to the scope of the inspection as outlined in B31.3, which is the Code for Process Piping. This code is part of the ASME (American Society of Mechanical Engineers) B31 Code for Pressure Piping and specifies requirements for materials and components, design, fabrication, assembly, erection, examination, inspection, and testing of piping. Inspection in this context applies to functions performed to ensure compliance with the code. These functions are integral to the quality and safety of the piping system and include activities such as examinations, tests, and verifications of design specifications and standards.
