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) are not be included in the gross beta quantification using the test method described in this document. This test method is applicable to the analysis of raw and drinking waters with low amounts of total soluble salts in the water. Limit of detection depends on the performance characteristics (background count rate and counting efficiency) of the counter used. It is the laboratory’s responsibility to ensure the suitability of this method for the water samples tested. As this method requires sample preparation in laboratory facilities, it is not suited for rapid, in-the-field analysis.

This International Standard provides general guidance for the design of test rooms intended for the sensory analysis of products. It describes the requirements to set up a test room comprising a testing area, a preparation area, and an office, specifying those that are essential or those that are merely desirable. This International Standard is not specific for any product or test type. NOTE The test space can be similar for food and non-food products that are evaluated using sensory methods. However, the test rooms might need to be adapted for each specialized use. Modifications to the design are often needed for specific products and for specific types of testing. This is particularly true if the test rooms are to be used for the evaluation of non-food products. This standard can be applicable for quality control functions.

ISO 23146:2012 specifies a method for the determination of the fracture toughness of advanced technical ceramics. The procedure makes use of single-edge V-notched bars, which are loaded in four-point bending until failure. It is applicable to monolithic ceramics with a grain size or major microstructural feature size larger than about 1 µm. The use of ISO 23146:2012 for yttria tetragonal zirconia polycrystal material (Y-TZP) is not recommended. The method might also be unsuitable for some other very tough or soft ceramics in which a sharp crack does not form at the root of the V-notch.

 

This document describes the procedures to prepare plutonium sources and  to measure the activity ratio of 238Pu to (239Pu + 240Pu) by alpha spectrometry. The alpha spectrometry method is used for the determination of isotopic abundance of 238Pu in combination with isotope amount ratios determined by mass spectrometry and eliminates the possible isobaric interferences of 238U in the latter method. It is applied to the analysis of purified solutions of plutonium in 2 mol/l to 4 mol/l nitric acid containing 50 µg to 200 µg of plutonium per millilitre, as may result from the chemical treatment and purification preceding plutonium isotopic analysis by mass spectrometry. This document is applied to plutonium solutions free from 241Am and those containing less than 10 % of other non-volatile impurities relative to the plutonium content. Otherwise purification should be carried out in accordance with ISO 8299[1]. The methods provided in this document are intended for use in conjunction or in parallel with mass spectrometry for the isotopic analysis of plutonium in spent-fuel solutions or nuclear-grade plutonium products.

This document provides an overview of relevant methods for the determination of specific parameters in solid soil improvers, including: — dry matter content; — quantity; — copper and zinc content; — chloride content; — nitrogen content; — P2O5 (phosphorus pentoxide) and K2O (potassium oxide) content.

If the soil improvers and/or growing media are not the components with the highest percentage in the blend, the European Standard relevant to the component with the highest percentage in the blend applies. In case a blend is composed of fertilising products mixed in equal quantities, the user of the standard decides which standard to apply. NOTE A soil improver consists of a single bulky (volume-building) component or a mix of bulky (volume-building) components (for example peat, wood fibres, coconut coir, compost, expanded perlite).
