Gas Turbines - Acceptance Tests
|Publication Date:||1 May 1989|

Scope and field of application
This International Standard specifies standard procedures and rules for the conduct and reporting of acceptance tests in order to determine and/or verify the power, thermal efficiency and other performance characteristics of gas turbine power plants. It defines standard conditions which should be used if no other conditions are agreed at the time of purchase.1) This International Standard is not intended to provide a basis for the conduct of test work generally aimed at development or research.
The extent of acceptance tests that are carried out on the manufacturer's premises and at site respectively are to be agreed between the parties.
The acceptance requirements will have been satisfied if the mandatory tests given in 1.4 have been fulfilled under the procedures laid down.
Optional tests may, however, be included but should not be considered necessary unless specifically agreed upon by the parties to the test at the time of the purchase.
This International Standard applies to open cycle gas turbine power plants using normal combustion systems and also includes closed cycle and semi-closed cycle gas turbine power plants. In cases of gas turbines using free piston gas generators or special heat sources (for exampie chemical process, nuclear reactors, furnace for a supercharged boiler), this International Standard may be used as a basis but will need to be suitably modified.
The primary object of the acceptance (mandatory) tests is to determine
a) power under specified operating conditions (gas power, if only a gas generator is supplied);
b) thermal efficiency, heat rate or specific fuel consumption under specified operating conditions;
c) adequacy of essential protective devices as defined in 7.1.3.
Optional tests may also be included, provided that these are specifically agreed upon by both parties at the time of purchase. For example, such tests may include any of the following items or others specified by national or local requirements:
a) performance of the governing system and protective systems as given in 7.2.1 and 7.2.2;
b) handling characteristics (for example, starting characteristics, time of loading);
c) amplitude and frequency of vibration;
d) stack emission;
e) waste heat recovery evaluation;
f) noise level;
g) thermal discharges;
h) anti-icing system.
