This document specifies procedures for measuring and reporting the noise emission of information technology and telecommunications equipment. NOTE 1 This document is considered part of a noise test code (see 3.1.2) for this type of equipment and is based on basic noise emission standards (see 3.1.1) ISO 3741, ISO 3744, ISO 3745, ISO 9295 and ISO 11201. The basic emission quantity is the A-…

This document specifies two laboratory test methods for the determination of the effective shear strength of soils under consolidated drained conditions using either a shearbox or a ring shear device. This document is applicable to the laboratory determination of effective shear strength parameters for soils in direct shear within the scope of geotechnical investigations. The tests included in…

This document gives guidelines on the handling, documentation, storage and processing of frozen tissue specimens intended for the examination of isolated proteins during the pre-examination phase before a molecular assay is performed. This document is applicable to any molecular in vitro diagnostic examination performed by medical laboratories and molecular pathology laboratories that evaluate…

This document specifies a method for the determination of gross alpha and gross beta activity concentration for alpha- and beta-emitting radionuclides using liquid scintillation counting (LSC). The method is applicable to all types of waters with a dry residue of less than 5 g/l and when no correction for colour quenching is necessary. Gross alpha and gross beta activity measurement is not…

This document specifies a test method for the determination of gross beta activity concentration in non-saline waters. The method covers non-volatile radionuclides with maximum beta energies of approximately 0,3 MeV or higher. Measurement of low energy beta emitters (e.g. 3H, 228Ra, 210Pb, 14C, 35S and 241Pu) and some gaseous or volatile radionuclides (e.g. radon and radioiodine) might not be…

This document provides standard procedures for the collection, handling and storage of soil for subsequent biological testing under aerobic conditions in the laboratory. It applies to the collection, handling and storage for assessing the effects of soil on microorganisms, invertebrates (e.g. survival, reproduction, growth, behaviour) and plants (e.g. development, growth). This document is not…

This document specifies dimensional requirements relating to test specimens prepared from plastics materials intended for processing by moulding, as well as to test specimens prepared by machining from sheets or shaped articles. It compiles the designations and dimensions of test specimens used for the acquisition of comparable data and also of other frequently used specimens. The following types…

This document provides guidance on the sampling of soils of — natural and near-natural sites, — natural arboreal areas including forests and woods, — areas used for agriculture (arable and pasture sites), — areas used for horticulture (including domestic gardens, allotments), and — areas used for special crop-cultivation, orchards, vineyards,…

This document describes the precision that can be expected from the gas chromatographic method that is set up in accordance with ISO 6974-1. The stated precision provides values for the magnitude of variability that can be expected between test results when the method described in ISO 6974-1 is applied in one or more competent laboratories. This document also gives guidance on the assessment of…

This document gives general guidance on the development of site investigation strategies and detailed guidance on the development of sampling strategies, when collecting information on — the average properties of soil, — the variability of soil properties, and — the spatial distribution of soil properties. It is applicable to soil samples intended for chemical testing…
