    1. Scope

    1.1 This specification covers bars, billets, and blooms of bearing-quality steel to be used in the manufacture of highly loaded anti-friction bearings.

    1.2 Supplementary requirements of an optional nature are provided and when desired shall be so stated in the order.

    1.3 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 from the two systems may result in non-conformance with the standard.
