1.1 General
The rules given in this document are applicable to thermal acceptance tests covering
a wide range of accuracy on steam turbines of every type, rating and application.
Only the relevant portion of these rules will apply to any individual case.
The rules provide for the testing of turbines, whether operating with either superheated
or saturated steam. They include measurements and procedures required to determine
specific enthalpy within the moisture region and describe precautions necessary to
permit testing while respecting radiological safety rules in nuclear plants.
Uniform rules for the preparation, carrying out, evaluation, comparison with guarantee
and calculation of measuring uncertainty of acceptance tests are defined in this standard.
Details of the conditions under which the acceptance test can take place are included.
Should any complex or special case arise which is not covered by these rules, appropriate
agreement is to be reached by manufacturer and purchaser before the contract is signed.
