4 Standards on safety and performance of household refrigerators Why a standard is needed To give a common harmonized approach to the evaluation and testing of a product To be used as common reference for the producer, the laboratory, the client, the Regulators, the Market surveillance Authorities To serve as reference for the international trade and acceptance of products worldwide

5 Safety of refrigerating appliances Refrigerators are covered by ​​ IEC Edition 7.1:2012 IEC supplements or modifies IEC Edition 5:2010 Appliances covered: refrigerators for household and similar use ice-makers with motor-compressor and ice-makers incorporated in frozen food storage compartments refrigerating appliances and ice-makers for use in camping, touring caravans and boats for leisure purposes.

6 Safety of refrigerating appliances Examples of appliances NOT covered by IEC : motor-compressors (IEC ); appliances intended to be used in the open air appliances designed exclusively for industrial purposes appliances with remote motor-compressors; commercial dispensing appliances and vending appliances (IEC ); commercial refrigerators and freezers (IEC ); commercial ice-cream appliances.

7 Safety of refrigerating appliances IEC covers safety requirements IEC does not cover: Performances and energy efficiency Fitness for use RoHs PAHs (Polycyclic Aromatic Hydrocarbons) WEEE

8 Safety of refrigerating appliances Main risks covered by IEC Series : Risks of electrical origin: access to live parts or parts that may be live in case of faults Risks due to contacts with hot accessible surfaces Risks due to access to moving parts Risks due to flames and fire

9 Safety of refrigerating appliances Main points of IEC Scope and definition Instructions and marking Accessibility to live parts Heating and abnormal use Construction: grounding connections, resistance of materials Protection to penetration of liquids or solids Insulation distances Resistance to fire/no spread of flames

10 Safety of refrigerating appliances Accessibility to live parts with a test finger to verify if no active parts are accessible For Class II appliances, only double or reinforced insulation can be touched by the test pin (pin 15 mm long, with 3 mm diameter). Accessibility to live parts (Cl. 8)

11 Safety of refrigerating appliances How the test is carried out?

12 Safety of refrigerating appliances Examples of different probes for accessibility to live parts (Cl. 8)

13 Scope: to verifiy that temperatures of accessible surface and components are within limit prescribed for the specific material Test set-up: appliances installed in a test corner and thermocouples positioned in the relevant parts of the appliance (e.g. components, accessible surfaces, plastic materials, wiring) Appliances supplied and temperatures measured with appropriate equipment & instruments Safety of refrigerating appliances Heating test (Cl.11)

14 Safety of refrigerating appliances Scope: to verifiy that penetration of water does not cause reduction in creepage and clearances Test set-up: appliances subjected to water penetration Product under test a luminaire, but test set-up is the same ! The results of the test: Protection against moisture (Cl.15 )

15 Safety of refrigerating appliances Scope: to verifiy that non operation of temperature control devices, or overload, or EMC phenomena, or failures in components, do not cause safety problems Test set-up: appliances subjected to consequences of unwished situations (e.g shortcircuit of thermostats) Some results of the test : Abnormal use (Cl.19 )

16 Safety of refrigerating appliances Scope: to verify that overturning of the product does not cause safety problems Test set-up: appliance placed on an inclined plane Stability Test (Cl.20 )

17 Safety of refrigerating appliances Scope: to verifiy that product resists to impacts Test set-up: appliance subjected to impacts with impact hammer Mechhanical resistance (Cl.21 )

18 Safety of refrigerating appliances Scope: to verifiy that means for connection to supply are suitable Tests: verification of terminals and supply cable subject to pull and push force Supply connection (Cl.25 & 26 )

19 Safety of refrigerating appliances Scope: to verifiy that means for earthing are suitable Tests: verification of suitability of earth connection Provision for earthing (Cl.27 )

20 Safety of refrigerating appliances Scope: to verify that plastic materials have adequate characteristics to avoid deformation or leakages or spread of fire Tests carried out: Ball pressure Resistance to heat and fire (Cl.30) Glow Wire CTI Current Tracking Index

21 Performance and noise emission of household refrigerators Covered by ​​ IEC Ed for performances and IEC Ed for noise Emission ​​ IEC is a stand alone standard IEC is a part 2 of EN Ed and shall be read with Ed Appliances covered by IEC and IEC : all refrigerators for household and similar use

22 Performance and noise emission of household refrigerators Appliances NOT covered by IEC and IEC ice-makers with motor-compressor and ice-makers incorporated in frozen food storage compartments appliances designed exclusively for industrial purposes appliances with remote motor-compressors; commercial dispensing appliances and vending appliances commercial refrigerators and freezers commercial ice-cream appliances.

23 IEC under significant revision process CDV circulated in May 2013 Comments by August 2013 By end 2013 it should be possible to release an FDIS, depending on comments from NCs News on standard for performance of household refrigerators New Edition should be published in 2014

24 Variety of standards used worldwide linked to regional regulatory measures, such as energy labelling. Revision aims at a global acceptance and application. The new Edition will have very significant changes and major improvements. Revision is in fact an integration of different worldwide standards into one Why a new edition

25 New Standard on Performance of household refrigerators IEC , Definitions and General conditions for testing: IEC : Determination of linear dimensions, volumes and areas - Energy consumption test IEC : Other checks air-tightness of doors, lids or drawer seals opening force of doors or lids durability of doors, lids and drawers mechanical strength of shelves and similar components storage temperatures, temperature rise test freezing test ice-making test cooling test (not in 1 st Edition)

26 New Standard on performance of household refrigerators Energy consumption tests: Performed with the appliance in empty condition rather than loaded with test packages Significant reduction of the uncertainty in the test result is expected The thermal capacity of frozen food compartments is reduced, the testing time will be shortened.

27 New Standard on performance of household refrigerators Energy consumption test Performed at two ambient temperatures (16 and 32 °C instead of only at 25 °C) Rated energy consumption calculated by a combination of the results at 16 and 32 °C The weighting factor to be defined and can be different depending on the world region Fresh food compartment temperature reduced to 4 °C

28 New Standard on performance of household refrigerators Energy consumption test: A new adaptive test algorithm defines the time needed for a stable and reproducible test Test time reduced from a 70 ÷ 120 h to 10 ÷ 30 h Very short test times for regular behaving products Test time automatically increases for products having an irregular control behavior Algorithm is also applicable to frost-free appliances This new procedure will reduce the uncertainty and the costs of the tests

29 New Standard on performance of household refrigerators Temperature performance testing Storage temperature tests still performed with packages The warmest package in frozen food compartments must meet the -18 °C to guarantee proper conservation Load scheme drastically simplified using only 0.5 kg packages A new cooling capacity performance test introduced for fresh food compartments

30 New Standard on performance of household refrigerators Due to changes in reference temperatures, ambient temperatures and procedures, changes to the rated energy consumption are evident for all products Rated energy consumption of refrigerators-only will increase Rated energy consumption of frozen food compartments will decrease Combination appliances will be between these two extremes.

31 New Standard on performance of household refrigerators The new energy consumption values can be matched reasonably to the current values, though actual values will be different for every product

32 Related parameters in a test under EEE Scheme Volume Noise Temperature Rising Time Storage Temperature Freezing capacity Energy- consumption

33 The impact of the new standard As the new global standard significantly differs from the current standard, many questions may arise. Points to be addressed: 1. The change in rated energy consumption of a series of appliances in various categories as a function of the weighing factor 2. The effect on the uncertainty of the test results 3. Have ambiguities been effectively removed? 4. Effect on testing costs

34 The new standard in the international arena High worldwide interest in the new IEC China new energy label will include the most important changes of the new standard (freezer unloaded, test at ambient temperature 16°C and 32°C, etc.) 2015 energy regulations in Australia/New Zealand will be based on the new global standard Europe will consider the new standard in revision process of Ecodesign and Energy labelling Regulations

36 Conformity Assessment ? Demonstration that specified requirements (IEC Standards) relating to a product, process, system, person or body are fulfilled Testing, inspection and certification are part of the concept of Conformity Assessment either as a stand alone activity or all together. Conformity Assessment of household refrigerating appliances

37 IECEE is operating Third Party conformity assessment schemes Third-party conformity assessment activity is performed by a person or body that is independent from the person or organization that provides the product, and of users of that product. Criteria for the independence of conformity assessment bodies and accreditation bodies are provided in the International Standards and Guides applicable to their activities Conformity Assessment of household refrigerating appliances under IECEE Scheme

38 Safety Category HOUS – Household and similar equipment Standars applied IEC and IEC Performances and energy efficiency Category E3 Standards applied IEC and IEC

39 Products are tested to IEC standards with provision for supplementary testing for national differences, when relevant. Reciprocal recognition of test results among all participating Certification Bodies simplifies the granting of certification or approval at national levels. CB Test Certificates and associated Test Reports facilitate obtaining secondary certifications. Conformity Assessment of household refrigerating appliances under IECEE Scheme
