TC 77
Name	TC 77
Type	Technical Committee

TC 77 is a technical committee focused on standards for the safety, performance, and electromagnetic properties of electronic and electrical equipment. It engages with international bodies, national institutes, industrial consortia, and regulatory agencies to produce normative documents used by manufacturers, laboratories, and certification bodies.

History

TC 77 was established amid discussions involving International Electrotechnical Commission, International Organization for Standardization, Institute of Electrical and Electronics Engineers, European Committee for Electrotechnical Standardization, American National Standards Institute, British Standards Institution, Deutsches Institut für Normung, Comité Européen de Normalisation, Japan Industrial Standards Committee, Standards Australia, Bureau of Indian Standards, Canadian Standards Association, International Telecommunications Union, World Health Organization, Food and Drug Administration (United States), European Commission, National Institute of Standards and Technology, Underwriters Laboratories, TÜV Rheinland, SGS S.A., Intertek Group plc, Bureau Veritas, CSA Group, ANSI-ASME, IEC 61000 series, ISO 9001, ISO/IEC 17025, RoHS Directive, Restriction of Hazardous Substances Directive, WEEE Directive, REACH regulation, Kyoto Protocol, Paris Agreement, Montreal Protocol, Basel Convention, OECD, World Trade Organization, GATT and others as part of a global effort to harmonize technical requirements. Over time, TC 77 coordinated responses to incidents and technological shifts involving Tesla, Inc., General Electric, Siemens, Samsung Electronics, Apple Inc., Sony Corporation, Panasonic Corporation, LG Electronics, Intel Corporation, AMD, NVIDIA, Qualcomm, Texas Instruments, Broadcom Inc., ABB Ltd, Schneider Electric SE, Bosch, Honeywell International Inc., and industrial stakeholders in emerging markets such as Huawei Technologies Co., Ltd., Xiaomi Corporation, and Lenovo Group Limited.

Membership comprises national committees and liaison organizations from stakeholders including United States of America, People's Republic of China, Federative Republic of Brazil, Russian Federation, Republic of India, Kingdom of Saudi Arabia, Republic of Korea, Japan, Federal Republic of Germany, French Republic, Italian Republic, Kingdom of Spain, Kingdom of Belgium, Swiss Confederation, Netherlands, Sweden, Norway, Finland, Republic of Poland, Republic of South Africa, Commonwealth of Australia, and regional bodies such as European Union, African Union, Association of Southeast Asian Nations, Gulf Cooperation Council, and Mercosur. Individual members include representatives from Underwriters Laboratories, TÜV SÜD, SGS, Intertek, Bureau Veritas, Siemens, Schneider Electric, Philips, Eaton Corporation, Rockwell Automation, Mitsubishi Electric, Honeywell, Johnson Controls International, STMicroelectronics, NXP Semiconductors, Infineon Technologies, Rohm Semiconductor, Fairchild Semiconductor International, and academic institutions such as Massachusetts Institute of Technology, Stanford University, University of Cambridge, Imperial College London, Technische Universität München, ETH Zurich, Tsinghua University, Peking University, University of Tokyo, Seoul National University, Indian Institute of Technology Bombay, and Indian Institute of Science.

Standards and Publications

TC 77 produces normative texts that are adopted into series such as IEC 61000 series, IEC 60601 series, IEC 62368 series, IEC 60664, IEC 60945, IEC 60068, IEC 60721, ISO 7637, ISO 16750, IEEE 519, IEEE 1641, CENELEC EN 55032, CENELEC EN 55024, ANSI C63.4, ANSI C63.10, MIL-STD-461, RTCA DO-160, E Marking, CE marking, and guidelines referenced by European Commission directives and United States Code of Federal Regulations. Publications include test method specifications, measurement techniques, limit curves, conformity assessment guidance, and technical reports referenced by accreditation bodies such as International Laboratory Accreditation Cooperation, Asia Pacific Accreditation Cooperation, and Inter-American Accreditation Cooperation.

Working Groups and Projects

Current and historical working groups collaborate on projects addressing radiated emissions, conducted emissions, immunity to electrostatic discharge, surge immunity, harmonics, flicker, and power quality. Liaison and joint projects have involved IEC TC 61, IEC TC 108, IEC SC 77A, ISO TC 22, ITU-R Study Group 5, CENELEC TC 210, ETSI, Eurelectric, SAE International, ASTM International, IETF, 3GPP, GSMA, Bluetooth SIG, Wi-Fi Alliance, and research consortia like Horizon 2020, CORDIS, EUREKA, Fraunhofer Society, Max Planck Society, CEA, CSIRO, A*STAR, and RIKEN.

Impact and Applications

TC 77 standards underpin certification of products from consumer electronics makers like Samsung Electronics, Apple Inc., Sony, LG Electronics, Panasonic, and Sharp Corporation to industrial suppliers such as Siemens, ABB, and Schneider Electric. They inform safety and compliance practices used by laboratories such as NPL, PTB, NIM, KRISS, and NIST and regulatory enforcement by agencies including Federal Communications Commission, European Union Agency for Railways, Transport Canada, Civil Aviation Administration of China, Australian Communications and Media Authority, and Japan Metrology Institute. TC 77 outputs affect interoperability initiatives like IECEx, ATEX, ISO/IEC JTC 1, Open Mobile Alliance, ONE M2M, Zigbee Alliance, Thread Group, and standards referenced in procurement by multinational organizations such as United Nations, World Bank, International Monetary Fund, and European Investment Bank.
