The electromagnetic compatibility problem is one of the important factors affecting the environment and product quality, and its standardization work has been cited Aroused widespread concern at home and abroad. In this regard, the IEC 61000 series of publications developed by the International Electrotechnical Commission (IEC) are General standards in the fields of industry, electrical engineering and energy, transportation, social undertakings and health, consumer quality and safety, are divided into There are six categories. overview, environment, limits, test and measurement technology, installation and mitigation guidelines, and general standards. my country has developed a series of publications The domestic transformation work has been developed, and the corresponding national standard system has been established. In this standard system, GB/T (Z)17624 "Electromagnetic Compatibility Overview" is a basic standard in the field of electromagnetic compatibility, which aims to describe The basic terms and definitions of electromagnetic compatibility, electromagnetic influence phenomena, historical basis, general parameters, etc., are intended to be composed of eight parts. ---Application and interpretation of basic terms and definitions of electromagnetic compatibility. The purpose is to explain and explain the design and evaluation of electromagnetic compatibility system The basic concepts and practical applications of various terms have important meanings. (GB/T 17624.1-1998) ---Methods for achieving functional safety in electrical and electronic systems of equipment related to electromagnetic phenomena. The purpose is to achieve exposure to electromagnetic Provide guidelines for the functional safety of electrical and electronic systems and devices in disturbances. (GB /Z 17624.2-2013) ---The effect of high-altitude electromagnetic pulse (HEMP) on civilian equipment and systems. The purpose is to describe what has actually been done in the world The effect that has been produced during the proposed electromagnetic pulse test. (GB /Z 17624.3-2021) --The historical basis for limiting equipment power frequency harmonic current conduction emission within -2kHz. The purpose is to describe the power frequency harmonics within 2kHz of the power grid The source of current conduction emission and its effect. (GB /Z 17624.4-2019) ---The effect of high-power electromagnetic environment (HPEM) on civil systems. The purpose is to provide the field and voltage for the development of high-power electromagnetic environment Background material on standards related to the effects of current on civil systems. (Expected to be part 5) ---Guidelines for the evaluation of measurement uncertainty. The purpose is to provide the evaluation method and background information of measurement uncertainty, and give relevant countries ---The power factor of a single-phase system under non-sinusoidal conditions. The purpose is to provide the definition of various electric power quantities and their non-sinusoidal conditions The relationship between. (Expected to be part 7) ---Future expectations of the phase angle of harmonic current emission and voltage in the public power supply network. The purpose is to provide information on the public power supply network Mainly information about the current conditions and future development of the phase angle of the 3rd and 5th harmonic currents. (Expected to be part 8) The formulation of GB /Z 17624.6 focuses on the evaluation method of measurement uncertainty, and describes the mathematical formula of the probability density function. The analysis and evaluation methods of formula and statistical calculation clarify the requirements for measurement data correction and calculation documents. The conformity assessment agency provides suggestions on the preparation of measurement uncertainty reports, and laboratories with similar influences can review these reports. By comparison, the domestic technical committees related to electromagnetic compatibility have the same treatment of measurement uncertainty. Summary of electromagnetic compatibility Part 6.Guidelines for Evaluation of Measurement Uncertainty1 ScopeThis document provides the evaluation method and background information of the measurement uncertainty, and gives the relevant national standards (from the IEC 61000 series of standards) Transformation) guide to general considerations of measurement uncertainty. The purpose of this document is to provide advice on the preparation of measurement uncertainty reports for technical committees, product committees and conformity assessment agencies. It is allowed to compare these reports between laboratories with similar influence; it makes the domestic electromagnetic compatibility (EMC) related The technical committee's treatment of measurement uncertainty is consistent. Any influencing factors of measurement uncertainty mentioned in this document should be regarded as examples. Technical committee responsible for formulating basic immunity standards It will be responsible for identifying the factors influencing the measurement uncertainty of its basic test method. This document describes the following. ---Measurement uncertainty (MU) evaluation method; ---The mathematical formula of the probability density function; ---Analysis and evaluation of statistical evaluation; ---Revision of measurement data; ---document. This document does not summarize the influence of all measurement uncertainties, nor does it specify how to consider when determining compliance with EMC requirements Uncertainty of measurement. Note. Some examples given in this document are from other IEC publications other than the IEC 61000 series of standards that have completed the evaluation procedures described here. These examples are used to illustrate the principle.2 Normative referencesThe content of the following documents constitutes an indispensable clause of this document through normative references in the text.
