This document specifies a method for the measurement of 99Tc in all types of waters by liquid scintillation counting (LSC). The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling, and test sample preparation. A filtration of the test sample is necessary. The detection limit depends on the sample volume and the instrument used. The method described in this document, using currently available LSC instruments, has a detection limit of approximately 5 Bq·kg-1 to 20 Bq·kg-1, which is lower than the WHO criteria for safe consumption of drinking water (100 Bq l-1)[3]. These values can be achieved with a counting time of 30 min for a sample volume varying between 14 ml to 40 ml. The method presented in this document is not intended for the determination of ultra-trace amount of 99Tc. The activity concentration values in this document are expressed by sample mass unit instead of sample volume unit as it is usually the case in similar standards. The reason is that 99Tc is measured in various matrix types such as fresh water or sea water, which have significant differences in density. The activity concentration values can be easily converted to sample volume unit by measuring the sample volume. However, it increases the uncertainty on the activity concentration result. The method described in this document is applicable in the event of an emergency situation, but not if 99mTc is present at quantities that could cause interference and not if 99mTc is used as a recovery tracer. The analysis of Tc adsorbed to suspended matter is not covered by this method. It is the user's responsibility to ensure the validity of this test method for the water samples tested.

This document applies to mechanical ventilation systems (including the mechanical part of hybrid systems) and full and (partial) air conditioning systems in non-residential (parts of) buildings. This document does not apply to: — heat generating systems and their control; — refrigerating systems and their control; — distribution of heating and cooling medium to the air handling units; — compressed air supplying systems; — water conditioning systems; — central steam generating systems for air humidifying; — electric supply systems. This document is not applicable to ventilation systems and air conditioning systems for industrial or other special process environments.

 

This International Standard establishes a system for the transliteration11Definitions, explanations for terms used (transliteration, transcription, etc.) appear in Annex A. of Thai characters into Roman characters. One set of rules is provided for a completely reversible stringent conversion where principles of transliteration are applied without exception. This Romanized transliteration system is a means of converting the Thai writing system into a Roman alphabet writing system. Since there are fewer Roman characters than Thai characters, diacritical marks, punctuation marks, and a combination of two Roman characters, or a digraph, are needed to represent one Thai character. The aim of this system is to provide a means of international communication of written messages in a form which permits the automatic transmission or reconstitution of these by humans or machines. This system of conversion is intended to provide complete and unambiguous reversibility. It is possible that the results obtained from this system will not provide for correct pronunciation of the original Thai text. However, they will serve as a means of finding the Thai graphisms automatically and thus to allow anyone with a knowledge of Thai to pronounce the Thai text correctly. An attempt to transpose a preposed vowel after an initial consonant may comfort those who are used to the Roman writing system where a vowel always follows a consonant to form a syllable, unless it is a syllable without an initial. It is best to leave the preposed vowel in the Thai transliteration system where it is, because a transliteration system is not a transcription system. Capital letters are reserved for writing the initial letter in proper nouns. It is unwise to make use of capital letters in the transliteration system for certain characters, otherwise common nouns and proper nouns cannot be distinguished from one another. This system is based on phonetic logic in the selection of transliterated representations, as much as possible, in order to lessen the burden on those who wish to learn the system.

This European Standard defines general terms relating to products of aluminium and aluminium alloys which are helpful for communication within the aluminium industry and with its customers . It includes terms dealing with aluminium products, processing, sampling and testing, product characteristics and different types of visual quality characteristics. It does not include terms dealing with bauxite mining, alumina and anode production and aluminium smelting. This European Standard tries to adhere as closely as possible to the terms and definitions used in other standards or documents. NOTE For materials other than aluminium, different definitions can apply to terms which are defined in this document. This European Standard tries to follow the "common language" as it is used in native English speaking countries, without giving preference to specific idioms of any one of these counties. In cases where in different English-speaking countries different terms are used for the same concept or different concepts refer to an identical term, the appropriate explanations are given.
