Class 5 Boiler Practice Exam 2025 - Free Boiler Certification Practice Questions and Study Guide

The operation of electric boilers is primarily regulated by CSD1, which stands for "Control Systems for Boilers and Water Heaters." This standard outlines the safety requirements and operational practices specifically for the control systems of various types of boilers, including electric models. It includes criteria for their design, installation, operation, and maintenance to ensure safe and efficient performance.

Each of the other standards mentioned serves different purposes. The ASME BPVC, or the American Society of Mechanical Engineers Boiler and Pressure Vessel Code, covers the design and construction of pressure vessels and boilers but is broader and not exclusively focused on electric boilers. NFPA 85 relates to the boiler and combustion systems hazards, providing guidelines to manage risks associated with different firing methods, while API 650 is focused on the design and construction of aboveground storage tanks, thus not relevant to the regulation of electric boilers.
