1.1 This specification covers niobium-titanium alloy billets, bars, and rods, at 46 to 48% titanium. This material is used in the manufacture of wire for superconducting applications.
1.2 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 independent of the other; SI values cannot be mixed with inch-pound values. SI units are stated in parentheses.
1.3 The following precautionary caveat pertains only to the test methods portion, Section 13, 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.
