scope:

1. Scope

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

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

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

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

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

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

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

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

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

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

1.2.4 Class U - Wheels may be used in service in which the wheel load and braking are low.

1.3 The use of two-wear wheels is recommended for freight car service.

1.4 The values stated in inch-pound units are to be regarded as the standard.

1.5 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.
