This standard provides for usual conditions. In addition, it provides for special conditions that have beenfound convenient or necessary at times in the industry, which may be invoked by agreement between the manufacturer and purchaser. The conditions chosen may affect the economics or performance, or both, of machines in a given situation.

Provisions where special agreement between manufacturer and purchaser may be invoked are as follows:

Subclause Provision

1.3.2 High ambient temperature

1.3.3 Special conditions of environment

1.4.1 Type test quantities

1.4.2 Routine overspeed and single phase or locked rotor test Routine commutation and characteristic test quantities, quality control, and sampling plan

1.5.6 Special conditions of electric input or output

4.2.3 Greatest continuous rating

5.2 Waiver of temperature-rise limits

7.1 Dielectric test

8.2.1 Commutation routine tests

8.2.3 Level of visible sparking

8.3.1 Interruption type tests

9.3.1 Maximum design speed

10.1.1 Routine test tolerances Assumed stray load loss

10.6.5 Assumed harmonic losses

10.7.4 Tolerance from contract curve

10.8.1, 10.8.2, 10.8.3 Routine test tolerances

11.2 Variation of performance with voltage

11.3 Load reduction under condition of low supply voltage

13.1 Commutator trueness measurement

13.2 Vibration measurement

13.3 Sound measurement

13.4 Shaft voltage

This standard parallels the major technical contents of International Electrotechnical Commission (IEC) Recommendation Publication 349, Rules for Rotating Electrical Machines for Rail and Road Vehicles. However, it differs from IEC recommendation 349 in important respects.

These differences have been called to the attention of the U.S. Committee of Experts for IEC Technical Committee 9, the International Mixed Committee on Electric Traction Equipment.

This standard was prepared by a working group under the sponsorship of the DC, PM, and Special Machinery Subcommittee of the Electric Machinery Committee of the IEEE Power Engineering Society.


This standard applies to rotating electric machinery which forms part of the propulsion and major auxiliary equipment on internally and externally powered electrically propelled rail and road vehicles and similar large transport and haulage vehicles and their trailers where specified in the contract.

Major auxiliary equipment includes equipment such as blower and compressor motors, motor-generator and motor-alternator sets, auxiliary generators, and exciters, usually larger than 3 kW.
