Cryogenic Systems – SSMS and ASME Equivalency LESHC
• ASME Equivalency Ruling on SSMS by LESHC for Design, Manufacture, and Inspection Requirements– LESHC Review of Pre-Manufactured Design – 8 June
2006 with manufacturer ACCEL (now BASC)– LESHC Meeting - 2 February 2009 – ASME Equivalency is
granted upon resolution of Actions Items.
