This specification covers one-wear, two-wear, and multiple-wear wrought carbon steel wheels for locomotives and cars, designated Classes L, A, B, and C, heat-treated, wheels.

1.1This specification covers one-wear, two-wear, and multiple-wear wrought carbon steel wheels for locomotives and cars, designated Classes L, A, B, and C, heat-treated, wheels.

1.2The service for which the various classes are intended is as follows:

1.2.1Class B or C wheels shall be used for freight cars in interchange service.

1.2.2Class B or C wheels are recommended for use on locomotives.

1.2.3For passenger car service, the various classes are intended generally as follows:

1.2.3.1Class L—High speed with more severe braking conditions than other classes and light wheel loads.

1.2.3.2Class A—High speed with more severe braking conditions, but moderate wheel loads.

1.2.3.3Class B—High speed service with severe braking conditions and heavier wheel loads.

1.2.3.4Class C—(1) Service with light braking conditions and heavier wheel loads.

1.2.3.5Class C—(2) Service with heavier braking conditions where off-tread brakes are employed.

1.3Supplemental requirements are provided for use where additional testing or additional restrictions are required by the purchaser. Supplementary requirements included in Specification A788/A788M may also be specified by the purchaser for forgings ordered to this specification. Any supplemental requirements apply only when specified in the purchase order.

1.4The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text and tables, the SI units are shown in brackets. 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 nonconformance with the standard.

1.5Unless the order specifies the applicable “M” specification designation, the material shall be furnished to the inch-pound units.

1.6This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7This 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.
