Scope and object
Scope
The rules given in this standard 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 shall take place are included.
Should any complex or special case arise which is not covered by these rules, appropriate agreement shall be reached by manufacturer and purchaser before the contract is signed.
Object
The purpose of the thermal acceptance tests of steam turbines and turbine plants described in this standard is to verify guarantees given by the manufacturer of the plant concerning:
a) turbine plant thermal efficiency or heat rate;
b) turbine thermodynamic efficiency or steam rate or power output at specified steam flow conditions;
c) main steam flow capacity and/or maximum power output.
The guarantees with their provisions shall be formulated completely and without contradictions (see 2.4). The acceptance tests may also include such measurements as are necessary for corrections according to the conditions of the guarantee and checking of the results.
