1 Scope This part of IEC 61000 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. It specifies limits of voltage changes which may be produced by an equipment tested under specified conditions and gives guidance on methods of assessment. This part of IEC 61000 is applicable to electrical and electronic equipment having an input current equal to or less than 16 A per phase, intended to be connected to public low-voltage distribution systems of between 220 V and 250 V line to neutral at 50 Hz, and not subject to conditional connection . Equipment which does not comply with the limits of this part of IEC 61000 when tested with the reference impedance Z ref of 6.4, and which therefore cannot be declared compliant with this part, may be retested or evaluated to show conformity with IEC 61000‑3‑11. Part 3-11 is applicable to equipment with rated input current ≤ 75 A per phase and subject to conditional connection . The tests according to this part are type tests. Particular test conditions are given in Annex A and the test circuit is shown in Figure 1. NOTE 1 The limits in this standard relate to the voltage changes experienced by consumers connected at the interface between the public supply low-voltage network and the equipment user’s installation. Consequently, if the actual impedance of the supply at the supply terminals of equipment connected within the equipment user’s installation exceeds the test im...

1 Scope This document specifies statistical considerations for the evaluation of unwanted radio frequency emissions of mass-produced products. NOTE 1 It is based on CISPR TR 16‑4‑3. The reasons for such statistical considerations are: a) that the abatement of interference aims that the majority of the products to be approved shall not cause interference; b) that the CISPR limits should be suitable for the purpose of type approval of mass-produced products as well as approval of single-produced products; c) that to ensure compliance of mass-produced products with the CISPR limits, statistical techniques have to be applied; d) that it is important for international trade that the limits shall be interpreted in the same way in every country. Therefore, this document specifies requirements and provides guidance based on statistical techniques. EMC compliance of mass-produced products with the requirements of this document are based on the application of statistical techniques that reassure the consumer, with an 80 % degree of confidence, that 80 % of the products of a type being investigated comply with the limi...

IEC 61851-21-2:2018 defines the EMC requirements for any off-board components or equipment of such systems used to supply or charge electric vehicles with electric power by conductive power transfer (CPT), with a rated input voltage, according to IEC 60038:2009, up to 1 000 V AC or 1 500 V DC and an output voltage up to 1 000 V AC or 1 500 V DC. This document covers off-board charging equipment for mode 1, mode 2, mode 3 and mode 4 charging as defined in IEC 61851-1:2017. This first edition, together with IEC 61851-21-1, cancels and replaces IEC 61851-21:2001. It constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 61851‑21:2001: a) this document addresses now only EMC related tests instead of other electrical tests; b) Clauses 2 and 3 have been updated; c) the port definition, the test-setups and their corresponding limits as well as the operation modes are defined more precisely; d) Annexes A to F have been added.

IEC 61000-4-20:2022 focuses on emission and immunity test methods for electrical and electronic equipment using various types of transverse electromagnetic (TEM) waveguides. These types include open structures (for example striplines and electromagnetic pulse simulators) and closed structures (for example TEM cells). These structures can be further classified as one-port, two-port, or multi-port TEM waveguides. The frequency range depends on the specific testing requirements and the specific TEM waveguide type. The object of this document is to describe TEM waveguide characteristics, including typical frequency ranges and equipment-under-test (EUT) size limitations; TEM waveguide validation methods for electromagnetic compatibility (EMC) tests; the EUT (i.e. EUT cabinet and cabling) definition; test set-ups, procedures, and requirements for radiated emission measurements in TEM waveguides; and test set-ups, procedures, and requirements for radiated immunity testing in TEM waveguides. NOTE Test methods are defined in this document to measure the effects of electromagnetic radiation on equipment and the electromagnetic emissions from the equipment concerned. The simulation and measurement of electromagnetic radiation is not adequately exact for the quantitative determination of effects for all end-use installations. The test methods defined are structured for a primary objective of establishing adequate reproducibility of results at various test facilities for qualitative analysis of effects. This document does not intend to specify the tests to be applied to any particular apparatus or system(s). The main intention of this document is to provide a general basic reference for all interested product committees of the IEC. For radiated emission measurements, product committees select emission limits and measurement methods in consultation with CISPR standards. For radiated immunity testing, product committees remain responsible for the appropriate choice of immunity tests and immunity test limits to be applied to equipment within their scope. This document describes test methods that are separate from those of IEC 61000‑4‑3. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: provide information on the testing of large EUTs (including cables); apply the work on measurement uncertainties by adapting the work completed in CISPR and TC 77 (for emissions and immunity); update the validation procedure for the test volume regarding field uniformity and TEM mode verification; provide information concerning two-port and four-port TEM waveguides; add a new informative annex (Annex I) dealing with transient TEM waveguide characterization; and add information dealing with dielectric test stands for EUTs.
