1.2Three grades of joint bars are defined for applications where non-heat treated bars are suitable:
1.2.1Grade 1, low-carbon, primarily for industrial and mine use.
1.2.2Grade 2, medium-carbon, primarily for industrial and mine use.
1.2.3Grade 3, high-carbon, for general use in standard railroad track. They may be used in the production of insulated track joints.
1.3The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
