This specification deals with carbon steel tee rails for use in railway track, including export and industrial applications. Rails shall be furnished by as-rolling, head hardening, or fully heat treatment processes. Hydrogen content shall be measured either during the continuous casting process or during ingot teeming. The rails shall conform to the chemical requirements for carbon, manganese, phosphorus, sulfur, and silicon. Rail soundness shall be evaluated by macroetch testing for both ingot and continuously cast steel. The rails shall conform to the Brinell hardness test requirements for standard carbon rails and high-strength rails.

1.1 This specification covers carbon steel tee rails of nominal weights of 60 lb/yd (29.8 kg/m) and over for use in railway track, including export and industrial applications.
1.2 Supplementary requirements S1 and S2 shall apply only when specified by the purchaser in the order.
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.
