This document specifies a method for the determination of the total metal content in leather using digestion of the leather and subsequent determination with inductively coupled plasma optical emission spectrometry (ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS), atomic absorption spectrometry (AAS) or spectrometry of atomic fluorescence (SFA). This method determines the total…

1 Scope 1.1 This Standard describes the methods for determining the level of depressurization and solutions to mitigate risk arising from depressurization. 1.2 This Standard applies to detached, semi-detached, and row houses equipped with an exhaust device(s). It also applies to houses with secondary suites equipped with a separate exhaust device(s). 1.3 This Standard does not address…

This document specifies a method for sampling and handling free-living nematodes from terrestrial field soils as a prerequisite for using them as bio-indicators (e.g. to assess the quality of a soil as a habitat for organisms). This document applies to all terrestrial biotopes in which nematodes occur. The sampling design of field studies in general is specified in ISO 18400-101. This document is…

This document specifies the content of electronic labelling in the form of QR codes on the outer packing of Chinese materia medica and decoction pieces. This document is applicable to the cultivation, production, sales, use units and consumers of Chinese materia medica and decoction pieces.

This document, referred to as the “glTF Specification” or just the “Specification” hereafter, describes the glTF file format.glTF is an API-neutral runtime asset delivery format. glTF bridges the gap between 3D content creation tools and modern graphics applications by providing an efficient, extensible, interoperable format for the transmission and loading of 3D content.

This document defines the gravimetric method for determining the contamination level of fluids used in hydraulic fluid power systems. The working instructions provided in this document serve for the gravimetric determination of dirt content of pressure fluids from mineral oil with additives. They are used in hydraulic systems with hydrostatic drive.

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…

IEC 60825-4:2022 is available as IEC 60825-4:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60825-4:2022 deals with basic issues concerning laser guards, including human access, interlocking and labelling, and gives general guidance on the design of protective housings and enclosures…

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.
