Much like The National Board did, ASME is now splitting out its relief systems into a new section. The NB created Part 4 – Pressure Relief Devices in 2017 and now ASME is following suit and has created Section XIII, Rules for Overpressure Protection (available 7/31/21). This new section in the 2021 edition of the BPVC will include:
- Rules relating to the pressure integrity and performance governing the construction and installation of pressure relief devices. Construction is limited to materials, design, fabrication, examination, inspection, testing and certification.
- Rules for device type certification of relieving capacity and flow resistance ratings including the rules for conducting the tests and analyses to determine the performance of pressure relief devices.
- Rules for overpressure protection by system design.
