1.1 This document — amplifies the general principles for designing experiments for the numerical estimation of the precision of measurement methods by means of a collaborative interlaboratory experiment; — provides a detailed practical description of the basic method for routine use in estimating the precision of measurement methods; — provides guidance to all personnel concerned with designing,…

ISO 20289:2018 provides a chemical method for technicians working with Total Reflection X-ray Fluorescence (TXRF) instrumentation to perform measurements of water samples, according to good practices, with a defined degree of accuracy and precision. Target users are identified among laboratories performing routine analysis of large numbers of samples, which also comply with ISO/IEC 17025. ISO…

This International Standard specifies methods for the estimation of measurement uncertainty of chemical and physicochemical methods in single laboratories based on validation data and analytical quality control results obtained within the field of water analysis. NOTE 1 The principles of the estimation of uncertainty specified in this International Standard are consistent with the principles…

Shows general principles, apparatus, sampling times and places, pre-sampling inspection and identification of lots, sampling of bilk grain, sampling of grain in bags, preparation of laboratory sample, and packing, labelling and dispatch of laboratory samples.

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 specifies characteristics of fresh and dry baker’s yeast, particularly those relating to general product properties, application performance, physical and chemical properties, microbiology, and nutritional value information. This document is primarily intended for use by the baking industry, but is also aimed at laboratory and food testers

This part of ISO 7206 specifies a test method for determining short-term deformation of a press-fit acetabular component for total hip joint replacement under specific laboratory conditions. It also defines the conditions of testing so that the important parameters that affect the components are taken into account and it describes how the specimen is set up for testing. The described method is…

This International Standard proposal specifies technical requirements and test method for temperature sensor in radiosonde. This International Standard is applicable to the temperature measurement traceable to SI unit in boom sensors according to variations of pressure and air speed under the simulated conditions of upper air. This proposed standard will mainly provide a) Terms and definitions…

ISO 4582:2017 specifies methods to determine changes in colour and other appearance properties, and variations in mechanical or other properties, of plastics that have been exposed to glass-filtered solar radiation, to natural weathering or to simulated solar radiation from a laboratory source. The procedure used to analyse data depends on whether the test used to characterize the materials being…

This document will specify methods for the determination of the water content of rock. This document is applicable to the laboratory determination of water content of rock samples
