4 Introduction and Objective  
 
This document has been prepared by the Saudi St andards, Metrology and Quality Organization 
(SASO) and will supersede the previous standard: 2664:2013" Household Refrigerators, Refrigerator-
Freezers and Freezers – Energy pe rformance, testing and labelling requirements". The standard was 
updated in order to:  
1- Re-classify the products under the standard scope 
2- Change the testing me thodology (now using IEC standard approved by SASO) 
3- Clarify the definitions for rated values , tested values and acceptance criteria. 
4- Update the label design 
 
The objective of this document is to provide detailed performance  and energy  labelling 
requirements that refrigerators, refrigerator- freezers and freezers need to meet in order to enter the 
Saudi market. 
  SAUDI STANDARD                                                                                      SASO 2664/2017

alternating current, with a nominal supply vo ltage of 230 V, including built-in appliances 
(b)  Refrigerators and refrigerator-freezers with a gross (total) capacity up to 1100 litres (~39 
ft3) 
(c)  Freezers with a capacity up to 850 litres (~30 ft3) 
The requirements in this standard are not applicable to electrically operated refrigerators employing 
an absorption refrigeration system and for commerc ial refrigerators, refr igerators-freezers and 
freezers.  
The values in the standard are in SI (metric) units. Any values given in parentheses are for 
information only.  
This Standard shall not apply to:  
(a) Refrigerating appliances primarily powered by energy sources other than electricity, such 
as liquefied petroleum gas (LPG),  kerosene and bio-diesel fuels 
(b) Battery-operated refrigerating appliances that can be connected to the mains through an 
AC/DC converter 
(c) Refrigerating appliances for tertiary sector  application where the removal of refrigerated 
foodstuffs is electronically sensed and that information can be automatically transmitted 
through a network connection to a remote control system for accounting 
(d) Appliances where the primary function is not t he storage of foodstuffs through refrigeration, 
such as stand-alone ice- makers  or chilled drinks dispenser

5. CRITERIA FOR APPLYING THE MINIMUM ENERGY PERFORMANCE STANDARD (MEPS) 
5.1 Declaration of rated values  
The declaration of the rated capacity shall be expr essed only in terms of litres (l) according to the 
following rules: 
 The declaration of the rated capacity shall be exp ressed in litres (l) as multiples of 1 litres 
 The declaration of the rated power shall be expressed in terms of watt (W) as multiples of 10 W 
 The declaration of the energy efficiency sha ll be expressed in % as a multiple of 0.1%  
 The rated annual energy shall be expressed in kWh as a multiple of 1 kWh 
5.2 Determining the Minimu m Energy Performance  
5.2.1	General	
The Minimum energy performance are based on the Energy Efficiency Index (EEI) which is 
established from the comparison with a reference appliance. 
Details for calculation of the EEI are given in annex B. 
5.2.2	Minimum 	Energy	Performance 	Standard 	for	Refrigerating 	Appliances 	
Refrigerating appliances within the scope of this regulation with a storage volume equal to or higher 
than 10 litres shall comply with the energy  efficiency index limits in Table 5.

22 ANNEX B – Calculation of the en ergy efficiency index (EEI) 
 
B.1 General Principles 
For the calculation of the Energy Efficiency Index (E EI), of refrigerating appliance model, the Annual 
Energy Consumption of refrigerating appliance is compared to its Standard Annual Energy Consumption.  
The Energy Efficiency Index (EEI) is calculated and rounded to the first decimal place, as:  
ൌ 100	ൈ	ܣ஼
஼ 
 Eq. (B1)
Where:  
 AE C = Annual Energy Consumption of the refrigerating appliance  
 SAE C = Standard Annual Energy Consumption of the refrigerating appliance.  
B.2 Determination of the Annual Energy Consumption AE C 
The Annual Energy Consumption (AEC ) is calculated in kWh/year and rounded to two decimal 
places, as:  
The Energy Efficiency Index (EEI) is calculated and rounded to the first decimal place, as:  
ܣଶସ௛	 
 Eq. (B2)
Where  
 E 24h is the energy consumption of the refrigerating appliance in kWh/24h and rounded to three 
decimal places.  
B.3 Determination of the Standard  Annual Energy Consumption (SAE C) 
The Standard Annual Energy Consumption (SAE C ) is calculated in kWh/year and rounded to two 
decimal places, as:  
The Energy Efficiency Index (EEI) is calculated and rounded to the first decimal place, as:  
ܪܥ  
Eq. (B3)
Where:  
 V eq is the equivalent volume of the refrigerating appliance 
 CH is equal to 50 kWh/year for refrigerating appliances with a chill compartment with a storage 
volume of at least 15 litres; other wise, CH is equal to 0 kWh/year.  
 The M and N values are given in Table B3 for each refrigerating appliance category.

23 B.4 Calculation of the Volume equivalent used  for the calculation of the Standard Annual 
Energy Consumption SAE C 
The equivalent volume of a refrigerating appliance is the sum of the equivalent volumes of all 
compartments. It is calculated in litres and rounded to the nearest integer as:  
஼ሻ
20௖ୀ௡
ܫܤ  
Eq. (B4)
Where: 
 n is the number of compartments  
 V c is the storage volume of the compartment(s)  
 T c is the nominal temperature of the compartment(s) as set out in Table 3  
 ሺଶହି்಴ሻ
ଶ଴ is the thermodynamic factor as set in Table B1 
 FF c , CC and BI are volume correction factors as set out in Table B2 
The thermodynamic correction factor ሺଶହି்಴ሻ
ଶ଴is the temperature difference between the nominal 
temperature of a compartment Tc (defined in Ta ble 2) and the ambient temperature under standard 
test conditions at + 25 °C, expressed as a ratio of  the same difference for a fresh-food compartment 
at + 5 °C.  
The thermodynamic factors for the compartments are set out in Table B1.

Type of compartment Nominal

Cellar compartment, specific beverage compartment + 12 0C 0.65 
Fresh-food storage compartment + 5 0C 1.00 
Chill compartment 0 0C 1.25 
Ice-making compartment and 0-star compartment 0 0C 1.25 
One-star compartment -6 0C 1.55 
Two-star compartment -12 0C 1.85

Notes: 
 (i) for multi-use compartments, the thermodynamic factor is determined by the nominal temperature as given in Table 2 of the coldest compartment type capable of being set by the end-user and maintained continuously 
according to the manufacturer’s instructions;  
(ii) for any two-star section (within a freezer) the t hermodynamic factor is determined at Tc = – 12 °C;  
(iii) for other compartments the thermodynamic factor is determined by the coldest design temperature 
capable of being set by the end-user and maintained continuously according to the manufacturer’s instructions.

Correction factor Value Conditions 
FF (frost-free) 1.2 For frost-free frozen-food compartment

CC (climate class) 1.2 For T class (tropical) appliances 
1.1 For ST (subtropical) appliances 
1.0 Otherwise 
BI (built-in) 1.2 For built-in appliances under 58cm in width 
1.0 Otherwise 
Notes: 
(i) FF is the volume correction factor for frost-free compartments.  (ii) CC is the volume correction factor for a given climate class. If a refrigerating appliance is classified in more than one climate class, the climate class with the highest correction factor is used for the calculation of the equivalent volume.  (iii) BI is the volume correctio n factor for built-in appliances 
 
B.5 Determination of the M and N coefficient used for calculation of the Standard Annual 
Energy Consumption SAE C 
 
The coefficient M and N are determined based upon the category of refrigerating appliance 
according with Table B3 
Table B3 – M and N values by refrigerating appliance category 
Category M N 
1 0.233 245 
2 0.233 245 
3 0.233 245 
4 0.643 191 
5 0.450 245 
6 0.777 303 
7 0.777 303 
8 0.539 315 
9 0.472 286 
10 (*) (*) 
(*) for Category 10 refrigerating appliances the M and N values depend on the temperature and 
star rating of the compartment with the lowest storage temperature capable of being set by the end-user and maintained continuously according to the manufacturer’s instructions. When only an ‘other compartment’ as defined in Table 3 is present, the M and N values for Category 1 are used. Appliances with three-star compartments or  food-freezer compartments are considered to 
be refrigerator-freezers
