Brief Introduction of IEC Scope and Structure of IEC/TC61 Standardization of IEC/TC61 IEC 60335 Series Standards Conformity Assessment Regulatory Environments Developing Countries Participation in IEC/TC61
The International Electrotechnical Commission (IEC) is a not-for-profit, non-governmental organization, founded in 1906. IEC is the leading global organization that publishes consensus-based International Standards and manages conformity assessment systems for electric and electronic products, systems and services, collectively known as electrotechnology. IEC publications serve as a basis for national standardization and as references when drafting international tenders and contracts.
Scope To prepare safety requirements for electrical appliances primarily for household purposes, but also for other equipment and appliances in similar fields where there is no IEC Technical Committee in existence. NOTE 1: TC 61 does not deal with appliances which are already explicitly covered by the scope of other IEC Technical Committees. NOTE 2: The work of TC 61 in fields other than household may lead to a recommendation that the work on that particular project should be transferred to a new Technical Committee.

IEC 60335 standard content TYPICAL HAZARDS COVERED Firmware corruption Examples of relational Clauses Clause 19 Abnormal operation Clause 22 Construction
IEC 60335 standard content PART 1 Safety requirements applicable to majority of appliances Written to minimize the need for Part 2 specific safety requirements Safety mitigation for similar hazards in different appliances have similar solutions Minimizes test costs without compromising user safety
IEC 60335 standard content PARTS 2 Safety issue mitigation achieved by Confirming the Part 1 requirements Modifying the Part 1 requirements, or Adding to the Part 1 requirements Defined terms are written in bold type Where definition concerns an adjective, the adjective and associated noun are in bold type
IEC 60335 standard content AMENDMENTS AND NEW EDITIONS Part 1 written to minimize the need for Parts 2 alignment amendments Large amendments can lead to a new edition Small third amendments must result in a new edition Electronic publication reduces the need for the two amendment limit
IEC 60335 standard content APPLIANCE INDUSTRY CONCLUSION Allow the TC Officers to decide on a third amendment rather than a new edition Reduces costs to stakeholders Government regulators Manufacturers Consumers Test laboratories Certification bodies Retailers
IEC 60335 standard development and future developing direction Increase use of programmable electronic to provide Functional safety outcomes Power management control Remote interrogation and repair of faulty appliances Remote updating of appliance functionality Remote control of appliances
IEC 60335 standard development and future developing direction This trend introduces additional hazards Cyber security Software integrity Hostility of EM environment Caused by geographic, acclimate and using environment
IEC 60335 standard development and future developing direction These hazards addressed by Update of software validation processes Single fault robustness of electronic hardware Up-skilling staff and up-dating test equipment for both Manufacturers and test Laboratories
IEC 60335 standard development and future developing direction Consumers demanding even safer appliances Reduction in non-functional surface temperatures Reduce risk of burns to venerable persons Children Infirm persons Use of scientific data to select acceptable temperatures
IEC 60335 standard development and future developing direction NEW APPLIANCES Additional ways to provide safety information On a web site On a DVD at point of sale Additional ways of indicating that an appliance is operating Audible signal Visual signal
IEC 60335 standard development and future developing direction Changes to standards made as a result of Field reports of accidents New features Changes in societal expectations for protection of persons and the environment
PRE-MARKET APPROVAL SYSTEMS Product approval required before sale Approval issued based on test report to standard (essentially a type 1a system) Some systems require factory inspection and follow up sample testing (essentially a type 3 or type 4 or type 5 system) Scheme types are defined in ISO/IEC 17067
POST-MARKET SURVEILLANCE SYSTEMS Normally require an SDoC according to ISO/IEC 17050-1 Supporting documentation to ISO/IEC 17050-2 Test report to standard usually a defense in law Regulator can declare standard deficient
APPLIANCE INDUSTRY CONCLUSION Deliverables other than full consensus standards not acceptable to Regulators TC 61 only produces deliverable type IS
Manufacturer s use certified components if economic Some appliance manufacturer s assemble appliances from pre-certified components Other manufacturer s design and incorporate components into the appliance these components aspects not available for general sale Certification bodies need to recognize that one size does not fit all
Standards need to recognize that one size does not all Basic safety publications Group safety publications Horizontal standards must take this into account
Importance of developing countries participation With the background of globalization, developing countries as emerging economies are playing more and more important roles in global activities. It is a global market. Getting involved in the global market means more opportunities for both going abroad and developing better at home. International standardization is one of most effective ways to get involved in the global market. Household electric appliance industry is one of the most important industries that matters people s livelihood in all countries. It is curial for developing countries to participate in the standardization activities in the industry.
Current situations of the industry in developing countries We found that there are three major issues in developing countries regarding the household electric appliance industry. Issues of governmental supervision 1) deficiency in laws, regulations & standards; 2) poor implementation of laws, regulations and standards; and 3) deficiency in conformity assessment, and etc.. Issues of industry development 1) lack of competitiveness, such as lack of knowledge of frontiers of the industry, lack of core technology, lack of advanced manufacturing techniques; 2) deficiency in self-discipline, i.e., knowingly violate marking disciplines. Issues of consumers safety awareness/consuming habits, for example, consumers willing to compromise quality over cheap price.
How standardization activities of IEC/TC61 could help? IEC/TC61 is an international platform. IEC/TC61 is an resource intensive platform. Standardization is an effective way to solve the aforementioned problem. And standard itself is productivity to a certain extent. The standardization activities of IEC/TC61 could help to 1) Strengthen governmental supervision 2) Promote the industry development 3) Prevent consumers better 4) Enhance international trade
How standardization activities of IEC/TC61 could help? How to strengthen governmental supervision? Realize the importance of standards by participating IEC/TC61 standardization activities. Use standards as an effective means to regulate the industry. Borrow experiences from developed countries and IEC/TC61 to improve and complete national supervision system. How to promote the industry development? Cultivate the awareness that standard is an effective way to enhance the competitiveness of the industry. Learn the technology frontiers of the industry by participating in IEC/TC61. Build effective correlation between core technology and standard. They could mutual promote each other. Use standardization to realize better self-regulation of the industry.
How standardization activities of IEC/TC61 could help? How to prevent consumers better? Cultivate consumers safety awareness by providing standard knowledge. Guide consumers consuming habits. Provide high quality products to the market. How to enhance international trade? International standards could eliminate trade barriers, which lays the basis for international trade. Both the imported countries and exported countries could make the best use of international standardization to enhance international trade of the industry.
