CONTAINED IN VOL. 01.05, 2017 Defines heat-treated carbon and alloy steel axles for mass transit and commuter cars in electric and locomotive hauled railway service.

1.1This specification covers heat-treated carbon and alloy steel axles for mass transit and commuter cars in electric and locomotive hauled railway service.

1.2This specification is for solid design roller bearing axles with machined bodies.

1.3Various axle designs are used for this service including motor and non-motor with either inboard or outboard journals.

1.4Supplementary requirements including those in the general requirements of Specification A788/A788M are provided for use when additional testing or inspection is desired. These shall apply only when specified individually by the purchaser in the order.

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

1.6The 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.

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.
