IEC TR 61439-0:2022 standards for low-voltage switchgear and controlgear assemblies, there are system and application details that are specified by the specifier to enable the manufacturer to produce an assembly that meets the needs and expectations of the specifier. IEC/TR 61439-0:2022, identifies from the specifier’s perspective those functions and characteristics that are defined when…

This document specifies a photometric titration method using EDTA for the determination of the total iron content of iron ores. This method is applicable to a concentration range of a mass fraction of 37,00 % to 72,00 % of total iron in natural iron ores, iron ore concentrates and agglomerates, including sinter products. This method does not apply as a referee method.

IEC 60384-1-1:2022 establishes a generic template and specifies requirements to the content of detail specifications for capacitors within the IEC 60384-X series. This part of IEC 60384-1 is applicable to the drafting of detail specifications for fixed capacitors for use in electronic equipment.

IEC 62841-4-7:2022 clause 1 of IEC 62841-1:2014, is applicable, except as follows: Addition: This document applies to pedestrian controlled walk-behind lawn scarifiers and lawn aerators which are designed for regenerating lawns by combing out materials such as grass, thatch and moss or cutting vertically into the lawn face using metallic tines; and/or rigid non-metallic tines which rotate…

This document specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss. It can be used to determine the colour of papers or boards that contain fluorescent whitening agents, provided the UV content of the illumination on the test piece has been previously adjusted to give the calibrated colorimetric value corresponding…

This document specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss. This document is primarily intended for measuring the colour of paper and board to be used in the graphic arts industry, where that industry specifies the measurement of colour under D50/2° conditions in accordance with ISO 13655. This method…

This document specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss. This document is not applicable to coloured papers or boards which incorporate fluorescent dyes or pigments. It may be used to determine the colour of papers or boards which contain fluorescent whitening agents provided the UV content of the…

This document provides specifications for natural rubber latex concentrate which has low protein content [low protein natural rubber (LPNR) latex], as follows: —    LPNR latex: field latex or concentrated latex pretreated with deproteinising agent, centrifuged and preserved after concentration with ammonia only, with an alkalinity of at least a mass fraction of 0,6 % calculated with respect to…

This document specifies a language-independent information model which can be used for the development of dictionaries used to store or provide information about construction works. The model is extended by instantiating content, such as further objects and their relationships, allowing the content to serve as an ontology, taxonomy, meronomy, lexicon and thesaurus. NOTE 1    Lexicons are…

This document provides a principle to determine the parameter settings and operating methods for the evaluation of the composition and structure of articular cartilage by dGEMRIC and T2-mapping MRI in humans with a typical example of the methods; each are distinct MRI technologies that allow for noninvasive observation of soft tissue characteristics. The methods provided in this document are…
