ICS numbers may be provided in addition, where applicable):   
HS: 8415 10xx : 
Single-phase non-ducted room air-conditioner namely  an encased assembly or assemblies of 
one or more evaporators, compressors and conde nsers, designed to be used together as a 
permanently-installed piece of equi pment to provide conditioned air to any enclosed space.  It 
includes a prime source of refrigeration for cooling and dehumidification and may include 
other means for dehumidifying, circulating and cleaning the air in the enclosed space.  It 
includes one or more evaporators, compresso rs and condensers.  Such equipment may be 
provided in more than one assembly, the separate  assemblies of which are intended to be used 
together. 
Single-phase non-ducted air-conditioner ha ving a total cooling capacity of: 
(i) 8.8kW or lower, in the case of casement or window ty pe air-conditioner1; 
(ii) 17.6kW or lower, in the case  of split type air-conditioner2 employing technologies 
that control the output of the comp ressor by start- stop operation; or 
(iii) 10kW or lower, in the case of split ty pe air-conditioner2 employing technologies that 
vary the output of the compressor, by means other than start-stop operation. 
1Casement or window type  air-conditioner refers to a fact ory assembly of components of a 
refrigeration system fixed on a comm on mounting to form a single unit. 
2Split type air-conditioner refers to an assembly of components of a refrigeration system fixed 
on 2 or more mountings to form a matched functional unit.  G/TBT/N/SGP/12

: 
Single-phase refrigerator namely a self-contained an assembly consisting of a thermally 
insulated cabinet for the stor age and preservation of foodst uff above 0°C (32ºF) and a 
refrigerating unit operating on the vapour compress ion principle and arranged to extract heat 
from within the cabinet, whether or not one or more freezer compartment with an adjusted 
volume of up to 900 litres. 
The adjusted volume of the single-phase refrigerator, means the sum of the adjusted volumes 
of the compartments or sections of the refrigerator, where the adjusted volume of a compartment or section is the product of the ra ted volume of that compartment or section and 
the corresponding volume correction factor (K) indicated below. 
Fresh Food Compartment/ Section Type: K = 1.00 
**** Freezer Compartment/Section Type: K = 1.79 *** Freezer Compartment/ Section Type: K = 1.79 
** Freezer Compartment/Section Type: K = 1.57 * Freezer Compartment/Section Type: K = 1.36 
Chill Compartment/Section Type: K = 1.13 
Cellar Compartment/Section Type: K = 0.75 The compartment/section type are defined in accordance with Section 3.3 of the standard ISO 
15502:2005 of the International Orga nization for Standardization. 
5. Title, number of pages and language(s) of the notified document:   
(i) The Environmental Protection and Management  Act (in English), available online at: 
http://statutes.agc.gov.sg/  
(ii) The Environmental Protection and Manageme nt (Energy Conservation) Regulations 
(12 pages, in English). 
The existing Environmental Protection and Mana gement Act, and Environmental Protection 
and Management (Energy Cons ervation) Regulations will be amended to implement 
minimum energy efficiency standards for registrable air-conditioners and refrigerators supplied in Singapore from 1 Sep 2011.  
6. Description of content:   
Introduction of minimum energy efficiency st andards for registrable air-conditioners and 
refrigerators supplied in Singapore. 
From 1 Sep 2011 onwards, all registrable air-c onditioners and refrigerators supplied in 
Singapore must comply with minimum energy efficiency standards specified below. 
For casement and window type air-conditioners , the Coefficient Of Performance (COP) > 
2.50.  G/TBT/N/SGP/12 
 Page 3 
 
 
  For split type (non-inve rter) air-conditioners with one indoor  unit (cooling capacity less than 
7kW), the COP > 2.96. 
For split type (non-inverter) air-conditioners wi th one indoor unit (cooling capacity equal to 
or more than 7kW), the COP > 2.50. 
For split type (non-inverter) air-conditioners with  more than one indoor unit (cooling capacity 
less than 7kW), the COP > 2.96. 
For split type (non-inverter) air-conditioners with  more than one indoor unit (cooling capacity 
equal to or more than 7kW), the COP > 2.64. 
For split type (inverter) air conditioners with one indoor unit (cooling capacity less than 
7kW), the COP > 2.96. 
For split type (inverter) air conditioners with one indoor unit (cooling capacity equal to or 
more than 7kW), the COP > 2.64. 
For split type (inverter) air-c onditioner with more than one i ndoor unit (cooling capacity less 
than 7kW), the COP > 2.96. 
For split type (inverter) air-c onditioner with more than one indoor unit (cooling capacity equal 
to or more than 7kW), the COP > 2.64. 
For refrigerator without fre ezer, the Annual Energy Consumption in kWh (AEC) < (368 + 
0.892 x Vadj tot) x 0.812. 
For refrigerator with freezer, the AEC < (465 + 1.378 x Vadj tot) x 0.699. 
For refrigerator with freeze r and through-the-door ice dispenser, the AEC < (585 + 1.378 x 
Vadj tot) x 0.646. 
7. Objective and rationale, including the nature of urgent problems where applicable:   
Objective: For the purposes of envi ronmental protection & conservation  
Rationale: Air-conditioners and refrigerators th at are not energy-efficient consume more 
energy to operate and lead to hi gher emissions of greenhouse gases. 
8. Relevant documents:   Notice will be published in th e Republic of Singapore’s Government 
Gazette when adopted.   
9. Proposed date of adoption:   
 
Proposed date of entry into force:    Notice will be published prior to the date of 
entry into force.
