IEEE Std 112:1984 pdf download.IEEE Standard Test Procedure for Polyphase Induction Motors and Generators.
This standard covers instructions for conducting and reporting the more generally applicable and acceptable tests to determine the performance characteristics of polyphase induction motors and generators. The tests described may be applied to both motors and generators, as needed. Additional tests, not specified herein, may be required to satisfy specific research or application needs. These procedures shall not be interpreted as requiring the making of any specific test in a given transaction.

3. Tests — General
3.1 Kinds of Tests. Polyphase induction machines are normally given a routine test, but may be given additional tests.
For typical routine tests refer to ANSI! NEMA MG1-1978 [5J,2 parts 12 and 20.
A typical form for reporting routine test data is shown in Section 8, Form A-i. A typical form for reporting additional test data is shown in Section 8, Form A-2.
3.2 Choice of Tests. A complete list of the tests covered by this standard is given in the Table of Contents.
The schedule of factory and field tests which may be required on new equipment is normally specified by applicable standards or by contract specifications. The manufacturer’s choice of method for factory or field tests on new equipment will govern, in lieu of prior agreement or contract specification.
3.3 Use of this Standard. After the method of test is chosen, all necessary data may be obtained by following the instructions and precautions given only in those subsections which contain, in their left-hand margins, the letter designating the method selected. For example:
when testing by Method B, reference need be made only to the paragraphs opposite the letter “B” or the word “AU,” which will be employed to designate subsections common to all methods. Many of these subsections include alternate methods for obtaining the necessary data. Unless otherwise specified, the manufacturer may choose the method best suited to the facilities available in such cases.
3.4 Precautions During Test. Since the performance of an induction machine is dependent not only upon the value of voltage and frequency but also on the wave shape and the balance in magnitude and phase angle of the voltages, correct data can be obtained only by careful measurement and by employing a suitable source of power.
