Solid recovered fuels — Determination of elemental composition by X-ray fluorescence
This document specifies the procedure for a determination of major and minor element concentrations in solid recovered fuel material by energy-dispersive X-ray fluorescence (EDXRF) spectrometry or wavelength-dispersive X-ray fluorescence (WDXRF) spectrometry using a calibration with solid recovered fuel reference materials or solid recovered fuel samples with known content. A semiquantitative…

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 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…
Fire hazard testing - Part 9-2: Surface spread of flame - Summary and relevance of test methods
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 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…
