This standard BS ISO 21159:2018 Ships and marine technology. Butterfly valves for use in low temperature applications. Design and testing requirements is classified in these ICS categories:
  • 47.020.30 Piping systems

This document specifies requirements for design, manufacture, and test methods of cryogenic butterfly valves in order to have an excellent quality leakage stability in a very low temperature service (−196 °C to 80 °C).

It is applicable to valves of nominal sizes: DN: 80, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600 corresponding to nominal pipe size (NPS): 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24.
