Question: 1 / 400

Pressure relief devices must be approved by which organization?

ANSI

ASME

Pressure relief devices are critical safety components in boiler systems, designed to prevent excessive pressure build-up that could lead to system failure or explosion. To ensure the reliability and efficacy of these devices, they must conform to strict safety standards. The American Society of Mechanical Engineers (ASME) is the organization responsible for establishing codes and standards specifically for the design and performance of pressure relief devices in a variety of applications, including boilers.

ASME's Boiler and Pressure Vessel Code outlines the requirements for the design, materials, and testing of pressure relief devices, ensuring they function as intended under anticipated service conditions. Compliance with ASME standards helps ensure that these safety devices operate effectively, providing peace of mind regarding the safe operation of boiler systems.

Other organizations listed, such as ANSI (American National Standards Institute), ISO (International Organization for Standardization), and ASTM (American Society for Testing and Materials), also develop standards and specifications, but ASME specifically focuses on pressure vessels and the related safety devices, making it the appropriate authority for the approval of pressure relief devices.
