Codes, Standards, and Regulatory Compliance
Core concepts
Understand the ASME Boiler and Pressure Vessel Code (Section I for power boilers, Section IV for heating boilers), the National Board Inspection Code, and jurisdictional requirements. Know the roles of the authorized inspector (AI), the manufacturer's data report, and the certificate of authorization. Learn about stamping, nameplate data, and the difference between code requirements and good practice.
Traps
Questions often confuse Section I and Section IV scopes, or treat the NBIC as a design code rather than an inspection/repair code. Watch for items that assume a boiler can be altered without an AI's involvement - alterations require approval. Also distinguish the ASME code from OSHA and environmental rules.
Worked example
A power boiler operating above 15 psig falls under ASME Section I. A heating boiler below 15 psig and 160 psig/250°F limits falls under Section IV. Rule of thumb: identify the scope first - pressure and temperature determine which code applies.
