L'ISO 9211 (toutes les parties) décrit les traitements de surface des composants et des substrats, à l'exclusion de l'optique ophtalmique (lunettes) par l'application de traitements optiques, et normalise leur spécification. Elle définit les caractéristiques générales et les méthodes d'essai et de mesure toutes les fois où cela est nécessaire, mais elle n'est pas…

IEC TR 61000-3-18:2024 which is a technical report, reports on the development of a methodology for adapting IEC equipment emission limits from IEC 61000-3-2 and IEC 61000-3-12 for use in regions not covered by these documents. It identifies gaps in the existing equipment emission limit standards concerning their international applicability and identifies public power system characteristics…

IEC 63145-22-20:2024 specifies the standard measuring conditions and measurement methods for determining the image quality of augmented reality (AR) type eyewear displays. This document applies to see-through type (AR glasses) eyewear displays using virtual image optics. See-through type displays (VR glasses), contact lens-type displays, and retina direct projection displays are out of the scope…

This document specifies a procedure for a chamber test with different options of chamber sizes to measure the formaldehyde concentrations in air from wood products under defined test conditions of temperature, relative humidity, loading and air exchange rate. Results obtained from this small-scale chamber test method can be used for quality control (factory production control – ‘FPC’) based on…

IEC 62629-52-1:2024 specifies the standard measurement methods and measurement conditions for determining the optical properties of aerial displays. This document excludes image quality of aerial displays, such as modulation transfer function (MTF) and resolution measurements.
