10、 Committee. It is identical with ISO 6141:1984 “Gas analysis Calibration gas mixtures Certificate of mixture preparation”, published by the International Organization for Standardization (ISO). ISO 6141 was prepared as a result of discussions in Technical Committee 158, Gas analysis, in which the UK
11、 has participated. BS 4559 was first published in 1970 as a single standard under the title “Methods for the preparation of gaseous mixtures”. The present revision is being issued in Parts to incorporate methods prepared by ISO/TC 158 and to provide for revision, where necessary, of the methods incl
12、uded in the 1970 edition which was withdrawn in 1981. This revision of BS 4559-4 differs from the previous edition, published in 1981 and identical with ISO 6141:1979, in that a number of minor technical changes have been introduced. This Part of BS 4559 supersedes BS 4559-4:1981 which is withdrawn.
13、 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 Standards; attention is drawn especially to the following.
14、 Wherever the words “International Standard” appear, referring to this standard, they should be read as “Part of BS 4559”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance w
15、ith a British Standard does not of itself confer immunity from legal obligations.

18、 Scope and field of application This International Standard gives a list of all the criteria required to define a gas mixture supplied under pressure in a cylinder and to be used for calibration purposes. These criteria shall be declared by the producer of the gas mixture. The producer of the gas mi
19、xture for calibration shall supply two copies of the list of these criteria: a) in the form of a certificate delivered at the same time as the invoice for the corresponding gas cylinder; b) in the form of a label attached to, or fixed on, the gas cylinder. 2 References ISO 6143, Gas analysis Determi
