Industrial valves - Isolating valves for low-temperature applications Part 2: Type Testing - new standard issued
What is it?:
This part of BS EN ISO 28921 specifies requirements for the type testing of isolating valves for lowtemperature applications to verify the performance of valves at a low temperature from -50°C down to -196°C. It does not apply to valves for cyrogenic services, designed in accordance with BS ISO 21011, used with cyrogenic vessels.
Why Is it Important?:
BS EN ISO 28921-2 was published in 2015. Following a vote in CEN it has now been adopted as an EN without modification.
