This document specifies a method for the physical pre-treatment and conditioning of water samples and the determination of the activity concentration of various radionuclides emitting gamma-rays with energies between 40 keV and 2 MeV, by gamma‑ray spectrometry according to the generic test method described in ISO 20042. The method is applicable to test samples of drinking water, rainwater,…

Le présent document prescrit les méthodes d’essai nécessaires pour le contrôle de la qualité des plaques de poly(méthacrylate de méthyle) (PMMA) plates extrudées avec deux ou trois parois, obtenues à partir de matériaux de grade incolore, transparent coloré, translucide ou opaque. La largeur minimale de la plaque est de 600 mm. Les principales applications de ces plaques sont la construction et l…

This document specifies guidelines for the development of specific textile floor covering maintenance and cleaning standards, procedures and criteria to reflect locally specific conditions. This document specifies the factors which are likely to impact the final results of textile floor covering cleaning, defining maintenance and cleaning terms to highlight differences. It establishes low-cost,…

This document specifies the test methods for quality control of poly(methyl methacrylate) (PMMA) extruded double- and triple-skin flat sheets, obtained from colourless and coloured transparent, translucent and opaque grades of materials. The minimum sheet width is 600 mm. The main applications of these sheets are in building and agriculture (greenhouses).

IEC 61097-2:2021(E) specifies the minimum performance requirements, technical characteristics and type-testing requirements of the emergency position-indicating radio beacon used in the Cospas-Sarsat satellite system (EPIRB), as required by the International Convention for Safety of Life at Sea (SOLAS) as amended, and which is associated with IEC 60945. When a requirement in this document is…

IEC TR 60909-4:2021 which is a Technical Report, is intended to give help for the application of IEC 60909-0 for the calculation of short-circuit currents in 50 Hz or 60 Hz three-phase AC systems. This document does not include additional requirements but gives support for the modelling of electrical equipment in the positive-sequence, the negative-sequence and the zero-sequence system (Clause 4…
