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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
