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 standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
