IEC 60674-3-1:2021 gives the requirements for biaxially oriented polypropylene film having a smooth or rough surface, corona treated when required for vacuum metallization. The films are for use as dielectric in capacitors. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application is based on the…

IEC 60695-9-2:2021 presents a summary of published test methods that are used to determine the surface spread of flame of electrotechnical products or materials from which they are formed. It represents the current state of the art of the test methods and, where available, includes special observations on their relevance and use. The list of test methods is not to be considered exhaustive, and…

IEC TR 62001:2021(E), which is a Technical Report, provides guidance on the state-of-the art of VSC technology in relation to harmonics and predicted future developments, on the harmonic profile of present and predicted future VSC architectures and how they are characterised and modelled – as voltage sources, current sources, or otherwise. It also assesses the harmonic impedance of VSC and the…

IEC 60695-2-13:2021 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 60695-2-13:2021 specifies the details of the glow-wire test to be applied to test specimens of solid…

This Software Package Data Exchange® (SPDX®) specification defines a standard data format for communicating the component and metadata information associated with software packages. An SPDX document can be associated with a set of software packages, files or snippets and contains information about the software in the SPDX format described in this specification.

IEC TR 62039:2021(E) presents the important material properties of polymeric materials used in outdoor insulation and, where applicable, lists standardized test methods including minimum requirements. If no standardized tests are available, the test methods reported in literature are summarized. This document is valid for insulating materials having polymeric insulation, which are used in…

IEC 60695-2-13:2021 specifies the details of the glow-wire test to be applied to test specimens of solid electrical insulating materials or other solid materials for ignitability testing to determine the glow-wire ignition temperature (GWIT). The GWIT is the temperature which is 25 K (or 30 K) higher than the maximum test temperature, determined during this standardized procedure, at which the…

IEC 61788-23:2021 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 61788-23:2021 addresses a test method for the determination of the residual resistance ratio (RRR), rRRR, of…

This document specifies the general requirements and test methods for herbal raw material and materia medica. This document provides minimum requirements for those herbal materials that are not covered by individual standards.
