LISUN has several senior engineers who are experts of the IEC International Electrotechnical Commission. They are responsible for the drafting and formulation of many of these standards, and also sponsored several IEC related meetings. LISUN has always been working closely with the IEC International Electrotechnical Commission, and can usually publish test instruments that fully comply with the IEC requirements at the first time, greatly enhancing the competitiveness of Chinese products exported overseas.

The International Electrotechnical Commission (IEC; in French: Commission électrotechnique internationale) is an international standards organization that prepares and publishes international standards for all electrical, electronic and related technologies – collectively known as “electrotechnology”. IEC standards cover a vast range of technologies from power generation, transmission and distribution to home appliances and office equipment, semiconductors, fibre optics, batteries, solar energy, nanotechnology and marine energy as well as many others. The IEC also manages four global conformity assessment systems that certify whether equipment, system or components conform to its international standards.
All electrotechnologies are covered by IEC Standards, including energy production and distribution, electronics, magnetics and electromagnetics, electroacoustics, multimedia, telecommunication and medical technology, as well as associated general disciplines such as terminology and symbols, electromagnetic compatibility, measurement and performance, dependability, design and development, safety and the environment.
IEC standards have numbers in the range 60000–79999 and their titles take a form such as IEC 60417: Graphical symbols for use on equipment. Following the Dresden Agreement with CENELEC the numbers of older IEC standards were converted in 1997 by adding 60000, for example IEC 27 became IEC 60027. Standards of the 60000 series are also found preceded by EN to indicate that the IEC standard is also adopted by CENELEC as a European standard; for example IEC 60034 is also available as EN 60034.
The IEC cooperates closely with the International Organization for Standardization (ISO) and the International Telecommunication Union (ITU). In addition, it works with several major standards development organizations, including the IEEE with which it signed a cooperation agreement in 2002, which was amended in 2008 to include joint development work. Standards developed jointly with ISO such as ISO/IEC 26300 (Open Document Format for Office Applications (OpenDocument) v1.0), ISO/IEC 27001 (Information technology, Security techniques, Information security management systems, Requirements), and CASCO ISO/IEC 17000 series, carry the acronym of both organizations. The use of the ISO/IEC prefix covers publications from ISO/IEC Joint Technical Committee 1 – Information Technology, as well as conformity assessment standards developed by ISO CASCO and IEC CAB (Conformity Assessment Board). Other standards developed in cooperation between IEC and ISO are assigned numbers in the 80000 series, such as IEC 82045–1.
IEC standards are also being adopted by other certifying bodies such as BSI (United Kingdom), CSA (Canada), UL & ANSI/INCITS (United States), SABS (South Africa), SAI (Australia), SPC/GB (China) and DIN (Germany). IEC standards adopted by other certifying bodies may have some noted differences from the original IEC standard.

IEC 61000-4-2: Electrostatic Discharge Immunity Test is the International Electrotechnical Commission’s immunity standard on Electrostatic Discharge (ESD). The publication is one of the basic EMC standards of the IEC 61000–4 series. The European equivalent of the standard is called EN 61000-4-2. The current version of the IEC standard is the second edition dated 2008-12-09. The basic standards (61000-4) are usually called by product or family specific standards, which use these basic standards as a common reference.
IEC 61000-4-4: Electrical Fast Transient (EFT) / EMC Burst Immunity Test Standard is the International Electrotechnical Commission’s immunity standard based on electrical fast transient (EFT) / burst transients. This publication is part of the greater IEC 61000 group of standards which is covered under IEC TR 61000-4-1:2016. The current third version of this standard (2012) replaces the second version (2004). The goal of this standard is to establish a common and reproducible reference for evaluating the immunity of electrical and electronic equipment when subjected to electrical fast transient/bursts on supply, signal, control and earth ports.
IEC 61000-4-5: Testing and Measurement techniques – Surge Immunity Test is the International Electrotechnical Commission’s international standard on surge immunity. The current version is Third Edition dated 2014-05-15. Power lines may be hit by surges from power switches and from lightning, and the standard defines test set-up and procedures, and classification levels.
IEC 61000-4-6: Immunity to Conducted Disturbances, Induced by Radio Frequency Fields relates to the conducted immunity requirements of electrical and electronic equipment to electromagnetic disturbances coming from intended radio-frequency (RF) transmitters in the frequency range 150 kHz up to 80 MHz. Equipment not having at least one conducting wire and/or cable (such as mains supply, signal line or earth connection) which can couple the equipment to the disturbing RF fields is excluded from the scope of this publication. The object of this standard is to establish a common reference for evaluating the functional immunity of electrical and electronic equipment when subjected to conducted disturbances induced by RF fields. The test method documented in IEC 61000-4-6:2013 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. This fourth edition cancels and replaces the third edition published in 2008 and constitutes a technical revision. It includes the following significant technical changes with respect to the previous edition:
