This document specifies the liquid chromatography tandem mass spectrometry method (LC-MS/MS) for the determination of chloramphenicol content of muscle tissue, casing, liver of meat and meat products, including livestock and…

This document lists the International Standards which are currently available for the determination of the chemical composition of nickels, ferronickels and nickel alloys (see Clause 4). It provides details on the range of application and gives the principle of the method described in each International Standard (see Clause 5). Annex A shows graphical representations of the content ranges of the…

This document specifies the procedure for a determination of major and minor element concentrations in solid recovered fuel material by energy-dispersive X-ray fluorescence (EDXRF) spectrometry or wavelength-dispersive X-ray fluorescence (WDXRF) spectrometry using a calibration with solid recovered fuel reference materials or solid recovered fuel samples with known content. A semiquantitative…

This document provides answers to questions which can arise when calculating indexes and contents according to ISO 16128-1 and ISO 16128-2. It clarifies conditions on process, solvents and carbon sources to qualify ingredients regarding the ISO 16128 series. Detailed examples, explaining how to use the ISO 16128 series are also provided.

IEC 60335-2-119:2021 deals with the safety of commercial electric packaging appliances using vacuum conditions for food preservation, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. These appliances are not intended for household and similar purposes. They are used for commercial preservation of food in areas not open to the public, for…

IEC 62153-4-16:2021 specifies a method to extrapolate the test results of transfer impedance to higher frequencies and the test results of screening attenuation to lower frequencies when measured with the triaxial set-up in accordance with IEC 62153-4-3, IEC 62153‑4‑4 and IEC 62153-4-15. This method is applicable for homogenous screens, i.e. screens having a transfer impedance directly…

IEC 62841-4-5:2021 This document applies to grass shears with a maximum cutting width of 200 mm designed primarily for cutting grass. This document does not apply to hedge trimmers. Hedge trimmers are covered by IEC 62841-4-2. The contents of the corrigendum of January 2024 have been included in this copy.

This document specifies required characteristics of a domain-neutral top-level ontology (TLO) that can be used in tandem with domain ontologies at lower levels to support data exchange, retrieval, discovery, integration and analysis. If an ontology is to provide the overarching ontology content that will promote interoperability of domain ontologies and thereby support the design and use of…
