The required test conditions are given in sections 8.1.1 and 8.1.2 of BS EN 15502-1. These include required fuel characteristics, control mode settings, etc. to ensure that the test results are repeatable and comparable. Limitations are stated, for example section 8.1.2.5 prescribes the requirement for tests to take place under thermal equilibrium conditions, with precautions taken to prevent thermostats or adjustable controls or an electronic temperature control system operating and affecting the gas rate, unless necessary for the specific test being conducted.
