The standard heating capacity tests shall be conducted in accordance with Annex A of ISO 5151 and Annex B of ISO 13253 and ISO 15042. The heating capacity and effective power input shall be measured during the standard heating capacity tests.
The half capacity test shall be conducted at 50 % of full load operation. The test tolerance shall bet 5 % of full load capacity for continuously variable equipment. For multi-stage equipment, if 50 % capacity is not achievable, then the test shall be conducted at the next step above 50 %.
The minimum capacity test shall be conducted at the lowest capacity control setting which allows steady-state operation of the equipment at the given test conditions.
If the minimum capacity tests are conducted, but if the required uncertainty of measurement specified in ISO 5151, ISO 13253 and ISO 15042 cannot be achieved, the alternative method of calculation shall be used. (Refer to 6.6.4 and 6.7.4.)
The manufacturer shall provide information on how to set the capacity if requested by the testing laboratories.
The low temperature heating capacity test shall be conducted at H2 condition in accordance with Annex A of ISO 5151 and Annex B of ISO 13253 and ISO 15042. The heating capacity and effective power input shall be measured during the low temperature heating capacity test.
