ASTM D1943-05(2012) 水的α粒子放射性的标准测试方法

1.1 This test method covers the measurement of alpha particle activity of water. It is applicable to nuclides that emit alpha particles with energies above 3.9 MeV and at activity levels above 0.02 Bq/mL (540 pCi/L) of radioactive homogeneous water. This test method is not applicable to samples containing alpha-emitting radionuclides that are volatile under conditions of the analysis. 1.2 This test method can be used for either absolute or relative determinations. In tracer work, the results may be expressed by comparison with a standard that is defined to be 100 %. For radioassay, data may be expressed in terms of alpha disintegration rates after calibration with a suitable standard. General information on radioactivity and measurement of radiation has been published 2 and summarized in Practice D3648. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This International Standard specifies four different methods, designated A to D, for the examination of colour.The previously most employed method for assessment of water colour in water treatment plants, limnological surveys etc. was based on the hexachloroplatinate scale (Reference [1]). Methods C and D are harmonized with this traditional procedure (References [2][3]).Method A involves examination of apparent colour by visually observing a water sample in a bottle. This gives only preliminary information, for example for use in field work. Only the apparent colour can be reported.Method B involves determination of the true colour of a water sample using

DS/ISO 13162:2012 水质碳14活度的测定液体闪烁计数法

This International Standard describes the conditions for the determination of 14C activity concentration in samples of environmental water or of 14C containing water using liquid scintillation counting.The scintillation phenomenon results from interaction of ionizing radiation with solvents and compounds exhibiting fluorescence (scintillators). Both solvents and scintillators constitute the scintillation cocktail. The scintillation mixture is achieved by adding the scintillation cocktail to the test sample in order to obtain a homogeneous mixture.Some examples of methods with sample pretreatment are described in Annexes C and D.NOTE 1 The method is applicab

This International Standard specifies a method to measure the 210Po activity concentration by alpha spectrometry in all kind of natural waters.The detection limit of this measurement depends on the volume of the sample, the counting time, the background count rate and the detection efficiency. In the case of drinking water, the analysis is usually carried out on the raw sample, without filtration or other pre-treatment.If suspended material has to be removed or analyzed, filtration at 0,45 ìm is recommended. The analysis of the insoluble fraction requires amineralisation step that is not covered by this International Standard (NF M 60-790-4(4)). In this cas

This International Standard specifies the conditions for the determination of tritium activity concentration in samples of environmental water or of tritiated water ([3H]H2O) using liquid scintillation counting.The choise of the analytical procedure, either with or without distillation of the water sample prior to dertemination, depends on the aim of the measurement and the sample characteristica (see References [1], [2], [3]).Direct measurement of a raw water sample using liquid scintillation counting has to consider the potential presence of other beta emitter radionuclides. To avoid interference with these radionuclides when they are detected, the quanti

ASTM D2688-11 无热传递条件下水腐蚀性的标准试验方法(重量损失法)

Since the two tendencies are inseparable for a metal to corrode and for water and the materials it contains to promote or inhibit corrosion, the corrosiveness of a material or the corrosivity of water must be determined in relative, rather than absolute, terms. The tendency for a material to corrode is normally determined by measuring its rate of corrosion and comparing it with the corrosion rates of other materials in the same water environment. Conversely, the relative corrosivity of water may be determined by comparing the corrosion rate of a material in the water with the corrosion rates of the same material in other waters. Such tests are useful, for example, for evaluating the effects of corrosion inhibitors on the corrosivity of water. Although this test methods is intended to determine the corrosivity of water, it is equally useful for determining corrosiveness and corrosion rate of materials. Examples of systems in which this method may be used include but are not limited to open recirculating cooling water and closed chilled and hydronic heating systems.1.1 This test method covers the determination of the corrosivity of water by evaluating pitting and by measuring the weight loss of metal specimens. Pitting is a form of localized corrosion: weight loss is a measure of the average corrosion rate. The rate of corrosion of a metal immersed in water is a function of the tendency for the metal to corrode and is also a function of the tendency for water and the materials it contains to promote (or inhibit) corrosion. 1.2 The test method employs flat, rectangular-shaped metal coupons which are mounted on pipe plugs and exposed to the water flowing in metal piping in municipal, building, and industrial water systems using a side stream corrosion specimen rack. 1.3 The values stated in SI units are to be regarded as standard, other units Values given in parenthesis are for information only. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
