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 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.

EN 1998-2 is intended to be applied to the design of new bridges in seismic regions. It covers the design of reinforced concrete, steel and composite steel-concrete bridges and provides guidance for the design of timber bridges. EN 1998-2 is applicable to the seismic design of bridges exploiting ductility in structural members or through the use of antiseismic devices. When ductility is exploited, this part primarily covers bridges in which the horizontal seismic actions are mainly resisted through bending of the piers or at the abutments; i.e. of bridges composed of vertical or nearly vertical pier systems supporting the traffic deck superstructure. It is also applicable to the seismic design of arched bridges, although its provisions should not be considered as fully covering these cases. Suspension bridges and masonry bridges, moveable bridges and floating bridges are not included in the scope of EN 1998-2.
