1.1 This specification covers steel joint bars for connecting steel rails in mine, industrial, and standard railroad track.
1.2 Three grades of joint bars are defined for applications where non-heat treated bars are suitable:
1.2.1 Grade 1, low-carbon, primarily for industrial and mine use.
1.2.2 Grade 2, medium-carbon, primarily for industrial and mine use.
1.2.3 Grade 3, high-carbon, for general use in standard railroad track. They may be used in the production of insulated track joints.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
