Abstract

Provides for acceptance tests of steam turbines of various types and capacities with appropriate measuring uncertainty. The rules provide for the testing of turbines, whether operating with either superheated or saturated steam. Uniform rules for the preparation, carrying out, evaluation, comparison with guarantee and calculation of measuring uncertainty of acceptance tests are also defined.
