This standard specifies a procedure to determine the relation between the water content and the dry density of soil and soil aggregates mixes when they are compacted in a standard mould by a 4.536 kg rammer dropped from a height of 457 mm. Three methods are used to determine this relation (see Chapter 5). NOTE — The laboratory compaction test methods described in this standard generally provide…

This document establishes a voluntary system for the identification of versions of audiovisual works and other content derived from or closely related to an audiovisual work (see Annex A). It is based on the International Standard Audiovisual Number (ISAN) system defined in ISO 15706-1. An ISAN combined with the version segment specified in Clause 4 constitutes an ISAN version identifier,…

IEC 60384-14:2023 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60384-14:2023 edition 5.0 and the previous IEC 60384-14:2013+AMD1:2016 CSV edition 4.1. Furthermore, comments from IEC TC 40 experts are provided to explain the reasons of the most relevant changes, or to clarify…

IEC 60384-14:2023 applies to capacitors and resistor-capacitor combinations intended to be connected to AC mains or other supply with a nominal voltage not exceeding 1 000 V AC (RMS), and with a nominal frequency not exceeding 100 Hz. This document includes also additional specific conditions and requirements for the connection to DC supplies with a rated voltage not exceeding 1 500 V DC. The…

This document provides statistical techniques for the determination of the reproducibility of the level of detection for a)    binary (qualitative) test methods for continuous measurands, e.g. the content of a chemical substance, and b)    binary (qualitative) test methods for discrete measurands, e.g. the number of RNA copies in a sample. The reproducibility precision is determined according to…

IEC 62722-2-1:2023 CMV contains both the official standard and its commented version.

Furthermore, comments from IEC SC 34D experts are provided to explain the reasons of the most relevant changes, or to clarify any part of…

This document defines particle size distribution by number and chemical content limits involving one grade of test aerosol made from combustion soot.

ISO 15000-3 specifies service interfaces, protocols and information model for an integrated registry and repository. The repository stores electronic content while the registry stores metadata that describes the content in the repository.

This document specifies methods for the chemical analysis of impurities present in aluminium oxide powders used as a raw material for fine ceramics. Aluminium oxide powders are decomposed by acid pressure decomposition, acid decomposition or alkali fusion. The calcium, chromium, copper, iron, magnesium, manganese, potassium, silicon, sodium, titanium, zinc and zirconium contents in the test…
