IEC 60938-2-1:2023 is applicable to the drafting of detail specifications for fixed inductors for which safety tests are required for use in electronic equipment. A blank detail specification is a supplementary document to the sectional specification and contains requirements for style, layout and minimum content of detail specifications. Detail specifications not complying with these…

IEC 60335-2-4:2023 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with the comprehensive content of the Standard. IEC 60335-2-4:2023 EXV includes the content of the references made to IEC 60335-1:2020. IEC 60335-2-4:2023 deals with the safety of: - stand-alone…

This document specifies box-based container format, referred to as JPEG XT, which is designed primarily for continuous-tone photographic content.

This document specifies the characteristics of categorial structures, representing nursing practice. The overall aim of this document is to support interoperability in the exchange of meaningful information between information systems in respect of nursing diagnoses, nursing actions and nurse sensitive outcomes. Categorial structures for nursing diagnoses, nursing actions, nurse sensitive…

IEC 62561-5:2023 is available as IEC 62561-5:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62561-5:2023 specifies the requirements and tests for earth electrode inspection housings (earth housings) installed in the earth and for earth electrode seals. Lightning protection system…

The objective of this document is to promote the harmonization of data and information reporting formats in order to provide the basis for the evaluation of occupational exposure with a view to allow for benchmarking capacity at the user level, technical review level, country level and global level (such as UNSCEAR) database or register on occupational exposure. Activity sectors and occupations (…

This document specifies a method for the determination of potential cation exchange capacity (CEC) and the content of exchangeable cations (Ca, K, Mg, Na) in soils using a molar ammonium acetate solution buffered at pH 7 as extractant. This document is applicable to all types of air-dry soil samples which have been prepared, for example, according to ISO 11464.

This document describes a gas chromatography – ion mobility spectroscopy (GC-IMS) method for the determination of the concentration of siloxanes in biomethane. The method is applicable to the following siloxanes: —     hexamethyldisiloxane (L2); —     octamethyltrisiloxane (L3); —     decamethyltetrasiloxane (L4); —     dodecamethylpentasiloxane (L5); —     hexamethylcyclotrisiloxane (D3); —    …

1 Scope 1.1 General This Standard specifies energy efficiencies for liquid-filled distribution transformers. The total ownership cost (TOC) methodology is recommended as the means for achieving these energy efficiencies, particularly for use by electric utilities. This Standard also specifies an optimal method for non-utility users, based on a modified TOC methodology that meets the conditions…

This document specifies a test with which in situ available concentrations of inorganic substances (such as heavy metals, arsenic and phosphorus) and organic substances in soil and soil-like materials can be simulated under forced aerobic and anaerobic conditions. The toxicity can then be estimated based on these available concentrations. The test described in this document aims to measure the…
