1.1 This specification covers the chemical, mechanical, and metallurgical requirements for unalloyed tantalum plate, sheet, strip, bar, and wire used in the manufacture of surgical implants.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values of the two systems may result in non-conformance with this standard.
