ISO/TS 12389:2009 describes the results of the inter-laboratory testing of the chemical analysis of cement by x-ray fluorescence. In the first instance, the inter-laboratory testing was carried out in Japan and Asian countries in accordance with JIS R 5204:2002. A total of 30 laboratories, 16 in Japan and 14 outside Japan, participated in the original testing programme. A further 12 European…

This document describes a laboratory test method, using an IGT1-type or a prüfbau2-type printability tester, for the preparation of specimens to evaluate the absorption rate of an ink on a substrate in offset lithography by setting-off the printed surface to an unprinted surface. This method describes testing with an amount of ink simulating either single colour or multi-colour printing. The…

Establishes arrangements for the preparation and execution of laboratory model tests, and evaluates the results obtained so that the hydraulic performance of a model turbine and of the corresponding prototype turbine can be ascertained. In general, the code applies to any type of hydraulic reaction or impulse turbine tested under laboratory conditions. See IEC 60995.

Scope 1.1.1 This Standard applies to packaged heat/energy-recovery ventilators (HRVs/ERVs) that consist of factory-assembled elements, including fans or blowers, in which heat or heat and moisture are transferred between two isolated airstreams. 1.1.2 This Standard specifies laboratory methods of test and procedures for rating the apparent effectiveness and heat-recovery efficiency of HRVs/ERVs…

ISO/TR 21865:2017 describes the relevant responsibilities of the involved manufacturers of fireworks articles and corresponding laboratories for the application of the ISO 25947 series and the ISO 26261 series. By applying this approach, a clear separation of the responsibilities of the manufacturers and the third party laboratories is achieved in order to demonstrate the conformity to the…

ISO 5902:2013 specifies laboratory measurement methods to determine the elastic properties of alpine skis. Its purpose is to calculate the resistance of defined parts of the ski to bending and torsion. The standard measurement procedures are recommended in order to ensure comparability between laboratory measurement data determined and published by ski manufacturers, institutions and others.

Covers the calculation of precision estimates and their use to specifications. In particular, it contains definitions of relevant statistical terms, the procedures to be adopted in the planning of an inter-laboratory test programme, the method of calculating the precision from the results of such a programme and the procedure to be followed in the interpretation of laboratory results in relation…

This document specifies a laboratory test method to determine the degree and rate of aerobic biodegradation level of plastic materials. This test method can also be applied to other materials. Biodegradation is determined by measuring the CO2 evolved by the plastic material when exposed to marine sediments sampled from a sandy tidal zone and kept wet with salt-water under laboratory conditions.…

This document gives guidelines on the handling, documentation, storage and processing of frozen tissue specimens intended for RNA examination 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 RNA extracted from…

ISO/TR 22971:2005 provides users with practical guidance to the use of ISO 5725-2:1994 and presents simplified step-by-step procedures for the design, implementation, and statistical analysis of inter-laboratory studies for assessing the variability of a standard measurement method and on the determination of repeatability and reproducibility of data obtained in inter-laboratory testing.
