1、Designation:A 583 93(Reapproved 1999)An American National StandardStandard Specification forCast Steel Wheels for Railway Service1This standard is issued under the fixed designation A 583;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revisi
2、on,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers one-wear,two-wear,andmultiple-wear cast carbon steel wheels for use on locomotive
3、sand cars,designated Class U,untreated,and Classes L,A,B,and C,heat-treated wheels.1.2 The service for which the various classes are intended isas follows:1.2.1 Class B or C wheels shall be used for freight cars ininterchange service.1.2.2 Class B or C wheels are recommended for use onlocomotives.1.
4、2.3 For passenger car service,the various classes areintended generally as follows:1.2.3.1 Class LHigh speed with more severe brakingconditions than other classes and light wheel loads.1.2.3.2 Class AHigh speed service with severe brakingconditions,but moderate wheel loads.1.2.3.3 Class BHigh speed
5、service with severe brakingconditions and heavier wheel loads.1.2.3.4 Class C(1)Service with light braking conditionsand heavier wheel loads.1.2.3.5 Class C(2)Service with heavier braking condi-tions where off-tread brakes are employed.1.2.4 Class UWheels may be used in service in which thewheel loa
6、d and braking are low.1.3 The values stated in inch-pound units are to be regardedas the standard.The values given in parentheses are forinformation only.1.4 This standard does not purport to address all of thesafety problems,if any,associated with its use.It is theresponsibility of the user of this
