ASTM B658/B658M-01
(Specification)Standard Specification for Seamless and Welded Zirconium and Zirconium Alloy Pipe
Standard Specification for Seamless and Welded Zirconium and Zirconium Alloy Pipe
SCOPE
1.1 This specification covers three grades of seamless and welded zirconium pipe.
1.2 Unless a single unit is used, for example corrosion mass gain in mg/dm2, the values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. SI values cannot be mixed with inch-pound values.
1.3 The following precautionary caveat pertains only to the test methods portion 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.
