Vandens kokybė. Visuminis alfa ir visuminis beta aktyvumas. Tyrimo metodas naudojant blyksnių skystyje skaičiavimą (ISO/DIS 11704:2025)

This document specifies a method to measure gross alpha and gross beta activity concentration for alphaand beta-emitting radionuclides using Liquid Scintillation Counting (LSC). The method is applicable to all types of waters with a dry residue of less than 5 g·l-1and when no correction for colour quenching is necessary. The method is applicable to test samples non-saline waters following proper sampling, handling and preparation. Gross alpha and beta measurements do not provide the exact radioactive content of a sample but estimate activity based on standard calibration sources. These measurements, known as the alpha and beta index, serve as screening tools for an initial assessment of total radioactivity. The method covers non-volatile radionuclides below 80 °C, since some gaseous or volatile radionuclides (e.g. radon and radioiodine) can be lost during the source preparation. The method is applicable to test samples of drinking water, rain water, surface and ground water as well as cooling water, industrial water, domestic and industrial waste water after proper sampling and test sample preparation (filtration when necessary and taking into account the amount of dissolved material in the water). The detection limit depends on the sample volume, the instrument used, the background count rate, the detection efficiency and the counting time. The detection limit of the method described in this document, using currently available liquid scintillation apparatus, is approximately 20 mBq·kg-1(α) and 100 mBq·kg-1(β), which is lower than the WHO criteria for safe consumption of drinking water 500 mBq·kg-1(α) and 1 000 mBq·kg-1(β).[4] This value can typically be achieved with a counting time of 500 min for a test sample volume of 0,08 l. The method described in this document is applicable in the event of an emergency situation, because the results can be obtained in less than 4 h by directly measuring water test samples without any treatment.

Šiluminės statybinių medžiagų ir gaminių savybės. Šiluminės varžos nustatymas apsaugotos karštosios plokštės ir šilumos srauto matuoklio metodais. Didelės ir vidutinės šiluminės varžos gaminiai

This document specifies principles and testing procedures for determining, by means of the guarded hot plate or heat flow meter methods, the thermal resistance of dry test specimens having a thermal resistance of not less than 0,5 m2·K/W. NOTE 1 The above limit is due to the effect of contact thermal resistances. An upper limit for measurable thermal resistance depends upon a number of factors described in this document, but a unique figure cannot be assigned. It applies in principle to any mean test temperature, but the equipment design in Annex D is essentially intended to operate between a minimum cooling unit temperature of -100 °C and maximum heating unit temperature of +100 °C. NOTE 2 Limits to the mean test temperature are only imposed by the materials used in the apparatus construction and by ancillary equipment. This document does not supply general guidance and background information (e.g. the heat transfer property to be reported, product-dependent specimen preparations, procedures requiring multiple measurements, such as those to assess the effect of specimen non-homogeneities, those to test specimens whose thickness exceeds the apparatus capabilities, and those to assess the relevance of the thickness effect). This document does not apply to cover measurements on moist products of any thermal resistance or measurements on thick products of high and medium thermal resistance.

ISO 28300:2008 covers the normal and emergency vapour venting requirements for aboveground liquid petroleum or petroleum products storage tanks and aboveground and underground refrigerated storage tanks designed as atmospheric storage tanks or low-pressure storage tanks. Discussed in ISO 28300:2008 are the causes of overpressure and vacuum; determination of venting requirements; means of venting; selection, and installation of venting devices; and testing and marking of relief devices. ISO 28300:2008 is intended for tanks containing petroleum and petroleum products but it can also be applied to tanks containing other liquids; however, it is necessary to use sound engineering analysis and judgment whenever ISO 28300:2008 is applied to other liquids. ISO 28300:2008 does not apply to external floating-roof tanks.

Bendrieji pigmentų ir užpildų tyrimo metodai. 5 dalis. Naftos absorbcijos vertės nustatymas (ISO/DIS 787-5:2025)

The oil absorption value is required to be compared with the value determined at the same time on an agreed sample of the product. The principle of the method is based on addition of linseed oil from a burette to the test portion. After each addition, rub the oil into the product until conglomerates are formed. Cease the addition of oil when a paste of smooth consistency has been formed. It should just spread without cracking or crumbling. Read the burette and note the quantity of oil used. The result is expressed in millilitres of oil per 100 g of product or in grams of oil per 100 g of product. - Cancels and replaces Part 5 of ISO/R 787-1968.
