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) might 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. The range of application depends on the amount of total soluble salts in the water and 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.

 

This document specifies a method for the gravimetric determination of soil water content as a volume fraction.

This document specifies minimum physical durability requirements and recommendations for workwear garments for circular economy in the textiles chain, based upon their intended use. This includes trims and fabrics to produce workwear garments. Workwear is exposed to intensive wear and tear and soiling, and therefore needs frequent care and maintenance to ensure that protection, comfort, style, image and hygiene properties continue to be provided over the entire lifetime of the garment. This document is applicable to all types of clothing designed for the workplace or specific professions, provided by the employer, or purchased privately to be used in professional context. Examples include general purpose workwear intended to prevent personal clothing or undergarments from soiling at the workplace to occupational clothing and uniforms. This document does not apply to personal protective equipment (PPE), medical devices (e.g. gowns), occupational clothing for product protection (clean room, electrostatic protected area (EPA)), swimwear, sportswear and accessories like gloves, scarfs, ties and hats.

ISO 20482:2013 specifies a standard test method for determining the ability of metallic sheets and strips having a thickness from 0,1 mm up to 2 mm and a width of 90 mm or greater to undergo plastic deformation in stretch forming. For materials that are thicker and when only narrower strips are available, tools of specified dimensions are provided, in which case subscripts are used, as shown in Table 1.

 

This document is published as a dual log standard and provides guidance on classification of gases and vapours. It describes a test method intended for the measurement of the maximum experimental safe gaps (MESG) for gas-air mixtures or vapour-air mixtures under normal conditions of temperature and pressure (20 °C, 101,3 kPa) so as to permit the selection of an appropriate group of equipment. This document also describes a test method intended for use in the determination of the auto-ignition temperature (AIT) of a vapour-air mixture or gas-air mixture at atmospheric pressure, so as to permit the selection of an appropriate temperature class of equipment. Values of chemical properties of materials are provided to assist in the selection of equipment to be used in hazardous areas. Further data may be added as the results of validated tests become available. The materials and the characteristics included in a table (see Annex B) have been selected with particular reference to the use of equipment in hazardous areas. The data in this document have been taken from a number of references which are given in the bibliography. These methods for determining the MESG or the AIT may also be used for gas-air-inert mixtures or vapour-air-inert mixtures. However, data on air-inert mixtures are not tabulated. Keywords: classification of gases and vapours, measurement of the maximum experimental safe gaps (MESG)

 

This document specifies definitions, principles of construction, requirements and methods for testing the performance of UV devices (240 nm to 290 nm nominal) for potable water installations according to EN 806-2 which are permanently connected to the building’s supply.
