ANNEX IV Measurement methods and calculations For the purposes of compliance and verification of compliance with the requirements of this Regulation, measurements and calculations shall be made using harmonised standards, or other reliable, accurate and reproducible methods, which take into account the generally recognised state-of-the-art methods and are in line with the following provisions set out below. The reference numbers of these harmonised standards have been published for this purpose in the Official Journal of the European Union . 1. General conditions for testing: (a) the ambient conditions shall correspond to Set 1, except for ice-cream freezers and gelato scooping cabinets which shall be tested in ambient conditions corresponding to Set 2, as set out in Table 2. (b) where a compartment can be set to different temperatures, it shall be tested at the lowest operating temperature. (c) refrigerated vending machines with compartments with variable volumes shall be tested with the net volume of the compartment with the highest operating temperature adjusted to its minimum net volume. (d) for beverage coolers, the specified cooling speed shall be according to the half reload recovery time.

Determination of the EEI: (a) For all refrigerating appliances with a direct sales function, the EEI, expressed in % and rounded to the first decimal place, is the ratio of the AE (in kWh/a) and the reference SAE (in kWh/a) and is calculated as: EEI = AE/SAE. (b) The AE, expressed in kWh/a and rounded to two decimal places, is calculated as follows: AE = 365 × E daily ; with: — E daily is the energy consumption of the refrigerating appliance with a direct sales function over 24 hours, expressed in kWh/24h and rounded to three decimal places. (c) The SAE is expressed in kWh/a and rounded to two decimal places. For refrigerating appliances with a direct sales function with all compartments having the same temperature class and for refrigerated vending machines, the SAE is calculated as follows: SAE = 365 × P × (M + N × Y) × C; For refrigerating appliances with a direct sales function with more than one compartment having different temperature classes, with the exception of refrigerated vending machines, the SAE is calculated as follows: ; where: (1) c is the index number for a compartment type ranging from 1 to n, with n being the total number of compartment types. (2) The values of M and N are given in Table 3.
