5、molybdosilicate spectrophotometric methodPart1: Silicon contents between0,05and1,0%”, published by the International Organization for Standardization (ISO), and supersedes method4 for the determination of silicon in BSI Handbook No.19. In1990 the European Committee for Standardization (CEN) accepted
6、 ISO4829-1:1986 as European Standard EN24829-1:1990. Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standa
7、rds; attention is drawn especially to the following. The comma has been used as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “International Standard” appear, referring to this standard, they should be read
8、 as “British Standard”. Cross-reference. The Technical Committee has reviewed the provisions of ISO377, to which reference is made in clause6, and has decided that they are acceptable for use in conjunction with this standard. A related British Standard to ISO377 is BS1837 “Methods for the sampling
9、of iron, steel, permanent magnet alloys and ferro-alloys”. Appropriate procedures from ISO377 will be incorporated in BS6200-2 “Methods of sampling and sample preparation”, which will be published in due course and which will supersede BS1837. A British Standard does not purport to include all the n
10、ecessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi andii, theE
