All equipment within the scope of this document shall have the cooling capacities and energy efficiency ratios determined in accordance with the provisions of this document and rated at the cooling test conditions specified in Table 1. All tests shall be carried out in accordance with the requirements of Annex A and the test methods specified in Clause 7. All tests shall be conducted with the equipment functioning at full-load operation, as defined in 3.25. The electrical input values used for rating purposes shall be measured during the cooling capacity test.
If the manufacturer of equipment having a variable-speed compressor does not provide information on the full-load frequency and how to achieve it during a cooling capacity test, the equipment shall be operated with its thermostat or controller set to its minimum allowable temperature setting.
The temperature conditions stated in Table 1 (columns T1, T2 and T3) shall be considered standard rating conditions for the determination of cooling capacity. For equipment intended for space cooling, testing shall be conducted at one or more of the standard rating conditions specified in Table 1.
Equipment manufactured only for use in a moderate climate similar to that specified in Table 1,column T1, shall have ratings determined by tests conducted at T1 conditions and shall be designated as type T1 equipment.
Equipment manufactured only for use in a cool climate similar to that specified in Table 1,column T2, shall have ratings determined by tests conducted at T2 conditions and shall be designated as type T2 equipment.
Equipment manufactured only for use in a hot climate similar to that specified in Table 1,column T3, shall have ratings determined by tests conducted at T3 conditions and shall be designated as type T3 equipment.
Equipment manufactured for use in more than one of the climates defined in Table 1 shall have marked on the nameplate the designated type (T1, T2 and/or T3). The corresponding ratings shall be determined by the standard rating conditions specified in Table 1.ISO 5151 pdf download.
