Specifies very accurate testing of steam turbines to obtain the level of performance with minimum measuring uncertainty. Defines uniform rules for preparing and carrying out an evaluation of the acceptance tests. Defines also the conditions under which the acceptance tests shall take place. The cost for conducting this test method will generally be justified economically for large and/or proptotype units.
