ISO 19581 specifies a screening test method to quantify rapidly the activity concentration of gamma-emitting radionuclides, such as 131I, 132Te, 134Cs and 137Cs, in solid or liquid test samples using gamma-ray spectrometry with lower resolution scintillation detectors as compared with the HPGe detectors (see IEC 61563). This test method can be used for the measurement of any potentially…

This standard shall be used as the basis for testing electrically powered air circulating fan heads and ceiling fans when air is used as the test gas. The scope is limited to air circulating fans with an input power greater than or equal to 125 W—except for ceiling fans that are larger than 1800 mm, which do not have a lower input power limit. The diameter of the fan being tested shall be limited…

This document specifies requirements and provides recommendations for the pre-examination phase of cell free DNA (cfDNA) from body fluid specimens other than blood, including but not limited to the collection, handling, storage, transport, processing and documentation of human body fluids, such as urine, cerebrospinal fluid (CSF), pleural effusions and saliva, intended for cfDNA examination.…

This document specifies test methods for verifying the capabilities of tyres for motorcycles. Of the test methods presented, only some can be required depending on the type of tyre to be tested. The tests are carried out in the laboratory under controlled conditions. This document includes a strength test for assessing the capability of the tyre structure, with respect to breaking energy. A…

This document compiles information about wood chips produced from raw materials as defined in ISO 17225-4: — quality classes and specifications; — sampling, sample preparation and determination of parameters which can be conducted on site and — practical information about parameters to be determined in external laboratories This document provides additional information related to selection of…

This document corresponds to the subsequent part of ISO 23300-1 "General requirements and test methods for rail welding" and specifies the requirements on rail aluminothermic welding, including the requirements for approval of an aluminothermic welding process, laboratory tests, contractor/welder, as well as the acceptance criteria of aluminothermic welds in track. In this document, 43…

This Standard specifies the standard test method useful to assess the performance of dust collection systems utilizing integrated fans (compact type dust collector), which shall be applied with or without flow control. This standard is not intended to offer the superiority or inferiority of performance between dust collectors, but specifies a standard test method that provides users with…

This document specifies a method for the determination of the dioxin‑like activity of water and wastewater by means of an AhR‑mediated reporter gene assay utilizing stably transfected mammalian cell line. This reporter gene assay is based on the activation of the mammalian AhR signalling pathway. This method is applicable to: —       drinking water; —       fresh water; —       groundwater…

This document describes the general principles pertaining to the sampling strategy, to the collection and conditioning of samples, to their transport to the laboratory and to the pre-treatment operations to be carried out prior to analysis.

This document specifies, for flexible and rigid cellular polymeric materials, laboratory procedures which are intended to imitate the effects of naturally occurring reactions such as oxidation or hydrolysis by humidity. The physical properties of interest are measured before and after the application of the specified treatments. Test conditions are only given for open cellular latex, both open-…
