IEC 60317-61:2020 specifies the requirements of polyester glass-fibre wound, resin or varnish impregnated bare, grade 1 or grade 2 enamelled rectangular copper winding wires, temperature index 180. The impregnating agent can be, for instance, epoxy, polyester, or polyesterimide resin based. NOTE For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature…

IEC 61643-12:2020 describes the principles for the selection, operation, location and coordination of SPDs to be connected to 50/60 Hz AC power circuits, and equipment rated up to 1 000 V RMS. These devices contain at least one non-linear component and are intended to limit surge voltages and divert surge currents. NOTE 1 Additional requirements for special applications are also applicable, If…

This document specifies practical performance tests for respiratory protective devices. The purpose of these tests is to subjectively assess certain properties, characteristics and functions of the RPD, when worn by test subjects in simulated practical use, which cannot be assessed by tests described in other standards.

IEC 61631:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61631:2020 specifies a test method for the mechanical strength of cores made of magnetic oxides. This test method…

IEC TS 62153-4-1:2014+A1:2020 deals with screening measurements. Screening (or shielding) is one basic way of achieving electromagnetic compatibility (EMC). However, a confusingly large number of methods and concepts is available to test for the screening quality of cables and related components, and for defining their quality. This technical specification gives a brief introduction to basic…

IEC TR 63212:2020 provides a feasibility assessment to determine if harmonization of environmental performance criteria is possible and would benefit the electrotechnical industry. This document is intended as a feasibility study report rather than a standard. It reports the possibility/opportunity to harmonize environmental performance criteria and, with it, the feasibility for future…

IEC TR 62629-51-1:2020 (E), which is a Technical Report, provides general information for the standardization of aerial displays. This document includes an overview of the technology, critical performance characteristics, issues of optical measurements, and other information.

IEC 62282-2-100:2020 provides safety related requirements for construction, operation under normal and abnormal conditions and the testing of fuel cell modules. This document deals with conditions that can yield hazards to persons and cause damage outside the fuel cell modules. Protection against damage inside the fuel cell modules is not addressed in this document, provided it does not lead to…
