ISOLATING VALVES FOR LOW-TEMPERATURE APPLICATIONS PART 2: TYPE TESTING NEW STANDARD BS ISO 28921-2:2015

Published: 18th February 2016 | Issue 36

What is it?
This part of ISO 28921 specifies requirements for the type testing of isolating valves for low-temperature applications to verify the performance of valves at a low temperature from – 50 °C down to – 196 °C.

Why is it important?
This is a new standard. The ISO working group responsible for this standard was led by a representative of Canada. It appears to have strong support from South Korea and the USA. There is no API equivalent specification. Those supplying valves for LNG and other low temperature fluid service should investigate the applications of this standard to their products as it is anticipated that in certain market areas this standard will be specified. It will be a competitor standard to BS EN 12567:2000.

Supersedes:
New standard. Nothing to supersede This standard is available from BSi Publications at a price of £152.00 (members price £76.00). Those people that are members of PSE/18 or PSE/18/1 committees are able to download the standard for free.
