IEC 63182-1:2020 specifies the dimensions of magnetic powder cores. This document also gives guidelines on the allowable limits of surface irregularities of magnetic powder cores. It is considered as a general specification useful in the dialogue between magnetic powder core manufacturers and users about surface irregularities. It is intended that this document will include magnetic powder cores…

IEC 61169-61:2020, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) for coaxial connectors with a 9,5 mm inner diameter of the outer conductor and quick lock coupling mechanism, characteristic impedance 50 Ω and an operating frequency of up to 8,5 GHz. Series Q4.1-9.5 connectors with socket centre contact are compatible with…

This document establishes a classification of low corrosivity of indoor atmospheres. It specifies the reference metals for which a corrosion attack after a defined exposure period is used for determining corrosivity categories of indoor atmospheres of low corrosivity. It defines corrosivity categories of indoor atmospheres according to corrosion attack on standard specimens. It indicates…

This document specifies methods for determining corrosion rates with standard specimens of metals in indoor atmospheres with low corrosivity. For this direct method of evaluation corrosivity, different sensitive methods can be applied using standard specimens of the following metals: copper, silver, zinc, steel and lead. The values obtained from the measurements are used as classification…

This document specifies two methods to determine the colour of raw natural rubber according to a standard colour scale: — Method A: colour matching against standard coloured glasses; — Method B: colour determination using colour spectrophotometer. In case of dispute, the preferred method is Method B.

IEC 60050-447:2020 gives the general terminology used in measuring relays and protection equipment, as well as general terms pertaining to specific applications and associated technologies. This new edition reviews and complements the previous one. It has the status of a horizontal standard in accordance with IEC Guide 108:2006. This terminology is consistent with the terminology developed in the…

This document specifies general terms and definitions relating to conformity assessment (including the accreditation of conformity assessment bodies) and to the use of conformity assessment to facilitate trade. The general principles of conformity assessment and a description of the functional approach to conformity assessment are provided in Annex A. Conformity assessment interacts with other…

IEC 61169-63:2020 which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) for RF coaxial connectors which can preferably be used with RF cables 60096 IEC 50-3 of IEC 60096-2. These connector patterns are for low power, quick connect/disconnect applications using a bayonet type coupling mechanism and are commonly known as type…

This document specifies general terms and definitions relating to conformity assessment (including the accreditation of conformity assessment bodies) and to the use of conformity assessment to facilitate trade. The general principles of conformity assessment and a description of the functional approach to conformity assessment are provided in Annex A. Conformity assessment interacts with other…

IEC 63260:2020 provides a structured framework for the incorporation of human reliability analysis (HRA) into probabilistic risk assessments (PRAs).<br /> This document is to enhance the analysis of human-system interactions in PRAs, to help ensure reproducible conclusions, and to standardize the documentation of such assessments. To do this, a specific HRA framework is developed from…
