ASME PTC 25-2023: Pressure Relief Devices
ASME PTC 25-2023 is a Performance Test Code published by the American Society of Mechanical Engineers (ASME). The "PTC" series of standards focuses on providing test procedures to determine the actual performance of equipment.
This code establishes a uniform method for conducting and reporting tests on various types of pressure relief devices, including both reclosing (e.g., safety relief valves) and nonreclosing (e.g., rupture disks) devices.
What it is Used For
The primary use of ASME PTC 25-2023 is to standardize the technical procedures for assessing the performance characteristics of pressure relief devices used to protect equipment like boilers, pressure vessels, and piping systems from dangerous overpressure or vacuum conditions.
It's crucial for manufacturers, certified laboratories, and plant operators to ensure safety and compliance with the ASME Boiler and Pressure Vessel Code (BPVC), which often mandates testing under PTC 25.
The tests defined in the code determine one or more of the following key performance indicators:
The standard provides instructions in two main parts: one for flow capacity testing (typically done by manufacturers in accredited labs for certification) and another for in-service and bench testing (performed by maintenance technicians to verify readiness in the field).
