9、999 National foreword This British Standard has been prepared by Technical Committee PTI/15 and is the English language version of EN ISO 6326-5:1997 Natural gas Determination of sulfur compounds Part 5: Lingener combustion method, published by the European Committee for Standardization (CEN). It is
10、 identical with ISO 6326-5:1989, published by the International Organization for Standardization (ISO). ISO 6326-5 was prepared by Technical Committee 158, Analysis of gases, in which the United Kingdom participated. BS EN ISO 6326-5 retains the secondary identifier BS 3156-11.4.5, so that it remain
11、s cross-referenced within the BS 3156 series of standards. Each Subsection of Section 11.4 of BS 3156 is identical with the corresponding Part of ISO 6326, and Section 11.4 of BS 3156 consists of the following Subsections: In the United Kingdom the preferred method is that given in Subsection 11.4.4
12、 of BS 3156. The flame photometric detector is available from most manufacturers of chromatographs, both laboratory and process units, and is applicable to any sulfur compound. By contrast, the electrochemical detector is available from a single supplier and is operated under completely different co
13、nditions, in order to measure carbonyl sulfide to those used for all other sulfur compounds. 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 with a British Standard does no
14、t of itself confer immunity from legal obligations.
