ASTM C1051-85(1994)e1

Standard Specification for Sodium (Na) as a Coolant for Liquid Metal-Cooled Reactors (Withdrawn 2000)

SCOPE
1.1 This specification is for sodium intended for use in liquid metal-cooled reactors and for related, non-reactor test and experimental systems.  
1.2 The values stated in SI units are to be regarded as the standard.  
1.3 The following precautionary caveat pertains only to Section 7 of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
