Often referred to as the "gold standard" for performance testing, the ASME PTC 6 code establishes the rules and procedures for conducting and reporting steam turbine tests. It is not merely a set of suggestions, but a technically rigorous framework designed to ensure a "level playing field" for manufacturers, owners, and operators. By adhering to this code, all parties involved in a test can be confident that the results represent a true and accurate measure of a turbine's capability, grounded in sound engineering principles.

Installed in the condensate or feedwater lines with precise upstream and downstream straight pipe lengths to measure primary flow.
ASME PTC 6 provides explicit, test-proven procedures for the accurate testing of steam turbines. The primary objective is to determine electrical output and heat rate (or steam rate) with the lowest possible level of uncertainty.
