This document defines terms relevant to optical coatings. These terms are grouped in four classes: Terms and definitions, definition of coatings by function, definitions of common coating imperfections and other definitions. This document identifies surface treatments of components and substrates excluding ophthalmic optics (spectacles) by the application of optical coatings and gives a standard…

This document contains tables for environmental tests and test parameters which can be used as a guideline for the selection of environmental tests. These include the selection of standardized tests according to ISO 9022 as well as additional parameters not described in ISO 9022 and necessary for the optical or photonic instruments. Ultimately, these tables specify the requirements to be met with…

IEC 62889:2024 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 62889:2024 describes two serial digital interfaces, Gigabit Video InterFace (GVIF) and Gigabit Video InterFace2 (…

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.

1 Scope 1.1 This performance Standard applies to circular precast concrete pipe, manhole (maintenance hole) sections, and accessories intended for a) use as sewer pipe for the conveyance of sewage, industrial wastes, and storm water; and b) the construction of culverts. 1.2 This Standard describes the following procedures for testing circular precast concrete pipe, manhole sections, and…

1 Scope 1.1 General This Standard provides minimum requirements and recommendations for the quantification and verification of the carbon intensity in a unit of concrete, including any carbon that is permanently sequestered during the production of the concrete and/or its input materials. Therefore, this number could be either positive or negative. The quantification calculation results in a…

1 Scope 1.1 Applicable equipment This Standard applies to newly produced household cooking gas appliances, hereinafter referred to as units or appliances, constructed entirely of new, unused parts and materials, and either floor-supported or built-in. 1.2 Household cooking gas appliances This Standard applies to household cooking gas appliances a) for use with natural gas; b) for use with…
