Scope
This standard specifies the classification and designations of hot-rolled steel for rail track of medium- and low-speed maglev trains, the content of orders, dimensions, shapes, weights, and allowable deviations, technical requirements, test methods, inspection rules, packaging, marking, and quality certificates. This standard applies to hot-rolled steel for rail track of medium- and low-speed maglev trains, including F-type steel for rail tracks and H-type steel for rail sleepers. F-type steel and H-type steel are collectively referred to as "steel sections" hereinafter.
