Refrigeration
Refrigeration standards address both the standard notion of a refrigerator, as well as a range of other related appliances such as ice-makers and frozen food storage. Developed by IEC, household refrigeration appliances rely on standardization due to often being components of other, larger appliances and therefore having to conform in order to be seamlessly integrated.
IEC 60335-2-104 Ed. 2.0 en:2021

IEC 60335-2-104:2021 is available as IEC 60335-2-104:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60335-2-104:2021 deals with the safety of electrical recovery and/or recycle equipment to recover and/or recycle refrigerant from air conditioning and refrigeration equipment. This applies to air-conditioning, heat-pumps and refrigeration equipment incorporating open drive or motor-compressors, their maximum rated voltages being not more than 300 V for single phase appliances and 600 V for all other equipment. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by service personnel in shops, in light industry and on farms, are within the scope of this standard. The appliances referenced above may consist of one or more factory made assemblies. If provided in more than one assembly, the separate assemblies are to be used together, and the requirements are based on the use of matched assemblies. This second edition cancels and replaces the first edition published in 2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Clause 1 - The scope has been edited to reflect that "appliance" in this document means recovery and/or recycle equipment to recover and/or recycle refrigerant from air-conditioning and refrigeration equipment. b) Clause 2 - Normative references were added. c) Clause 3 - Some definitions were deleted, some were added. d) Subclause 7.1 - Some markings were deleted, some were added. e) Subclause 7.6 - Symbols were added for “read operator’s manual”, “operator’s manual; operating instructions” including coloring are placed in visible location; maximum allowable pressure markings following X MPa. f) Subclause 19.11.4 was modified. g) Subclause 21.1 was modified. h) Subclause 21.2 was modified. i) Subclause 22.102 was modified. j) Subclause 22.104.1.1 was modified. k) Subclause 22.104.5 was modified. l) Subclause 22.104.10 was modified. m) Subclause 22.104.11 was modified. n) Subclause 22.105.1 was modified. o) Subclause 22.107 was modified. p) Subclause 30.2 was moved to Clause 29. q) Annex AA was deleted and replaced with Annex AA. r) Annex BB was deleted and replaced with former IEC 60335-2-104 Annex CC (normative) Compatibility requirements following addition to Annex BB. s) Annex DD was deleted and replaced with Annex CC. t) New Annex DD was added. u) New Annex EE was added.

IEC 62552-1 Ed. 1.0 b:2015
Household refrigerating appliances - Characteristics and test methods - Part 1: General requirements
IEC 62552-1:2015 specifies the essential characteristics of household refrigerating appliances, cooled by internal natural convection or forced air circulation, and establishes test methods for checking the characteristics. For the purposes of declaration, the tests defined in this part of IEC 62552 are considered to be type tests to assess the fundamental design and operation of a refrigerating appliance. This part of IEC 62552 does not define requirements for production sampling or conformity assessment or certification. This part of IEC 62552 does not define a regime for verification testing as this varies by region and country. When verification of the performance of a refrigerating appliance of a given type in relation to this standard is necessary, it is preferable, wherever practicable, that all the tests specified be applied to a single unit. The tests can also be made individually for the study of a particular characteristic. IEC 62552-1, -2 and -3 cancel and replace the first edition of IEC 62552 published in 2007. IEC 62552-1, -2 and -3 constitute a technical revision and includes the following significant technical changes with respect to IEC 62552:2007: a) All parts of the standard have been largely rewritten and updated to cope with new testing requirements, new product configurations, the advent of electronic product controls and computer based test-room data collection and processing equipment. b) In Part 1 (this part) there are some changes to test room equipment specifications and the setup for testing to provide additional flexibility especially when testing multiple appliances in a single test room.
IEC 62552-2 Ed. 1.0 b:2015
Household refrigerating appliances - Characteristics and test methods - Part 2: Performance requirements
IEC 62552-2:2015 specifies the essential characteristics of household refrigerating appliances cooled by internal natural convection or forced air circulation, and specifies test methods for checking the characteristics. This part of IEC 62552 describes the methods for the determination of performance requirements. Although there is some commonality in the set-ups for different tests (and so it may be an advantage to apply them all to one sample), these are separate tests to evaluate specific characteristics of the sample being tested. This part of IEC 62552 does not specify a procedure to generalise the results from sample test results to a prediction of the characteristics of the whole population from which that sample was selected. IEC 62552-1, IEC 62552-2 and IEC 62552-3 cancel and replace the first edition of IEC 62552 published in 2007. IEC 62552-1, IEC 62552-2 and IEC 62552-3 together constitute a technical revision and include the following significant technical changes with respect to IEC 62552:2007: - A cooling capacity test has been added in Part 2 (this part). - A pull-down test has been added in Part 2 (this part). - Performance tests have been added for wine storage appliances in Part 2 (this part).
IEC 62552-3 Ed. 1.0 b:2015
Household refrigerating appliances - Characteristics and test methods - Part 3: Energy consumption and volume
IEC 62552-3:2015 specifies the essential characteristics of household and similar refrigerating appliances cooled by internal natural convection or forced air circulation, and establishes test methods for checking these characteristics. This part of IEC 62552 describes the methods for the determination of energy consumption characteristics and defines how these can be assembled to estimate energy consumption under different usage and climate conditions. This part of IEC 62552 also defines the determination of volume. - All parts of the standard have been largely rewritten and updated to cope with new testing requirements, new product configurations, the advent of electronic product controls and computer based test-room data collection and processing equipment. - For more efficient analysis and to better characterise the key product characteristics under different operating conditions, the test data from many of the energy tests in Part 3 (this part) is now split into components (such as steady state operation and defrost and recovery). The approach to determination of energy consumption has been completely revised, with many internal checks now included to ensure that data complying with the requirements of the standard is as accurate as possible and of high quality. - Part 3 (this part) now provides a method to quantify each of the relevant energy components and approaches on how these can be combined to estimate energy under different conditions on the expectation that different regions will select components and weightings that are most applicable when setting both their local performance and energy efficiency criteria while using a single set of global test measurements. - For energy consumption measurements in Part 3 (this part), no thermal mass (test packages) is included in any compartment and compartment temperatures are based on the average of air temperature sensors (compared to the temperature in the warmest test package). There are also significant differences in the position of temperature sensors in unfrozen compartments. - The energy consumption test in Part 3 (this part) now has two specified ambient temperatures (16°C and 32°C). - A load processing energy efficiency test has been added in Part 3 (this part). - Tests (both performance (Part 2) and energy (Part 3 (this part)) have been added for wine storage appliances.
