10、6 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS EN ISO 11734:1999 ii BSI 06-1999 National foreword This British Standard is the English language version of EN ISO 11734:1998. It retains a dual identifier as BS 6068-5.21:1996. It is identical with ISO 11734:1995 published by the International Organiz
11、ation for Standardization (ISO). The international standard was prepared by ISO Technical Committee 147, Water quality, with the active participation and approval of the UK. BS 6068 is being published in a series of Parts subdivided into Sections that will generally correspond to particular internat
12、ional standards. Sections are being, or will be, published in Parts 1 to 7, which, together with Part 0, are listed below: Part 0: Introduction; Part 1: Glossary; Part 2: Physical, chemical and biochemical methods; Part 3: Radiological methods; Part 4: Microbiological methods; Part 5: Biological met
13、hods; Part 6: Sampling; Part 7: Precision and accuracy. NOTEThe tests described in this Section of BS 6068 should only be carried out by suitably qualified persons with an appropriate level of biological expertise. Standard biological procedures should be followed throughout. Textual errors. When ad
14、opting the text of the international standard, the textual errors listed below were discovered. They have been marked in the text and have been reported to ISO in a proposal to amend the text of the international standard. In 6.7, line 4, after “(e.g.” insert “producing about”. In 8.1, in line 5 of
15、the last paragraph delete “other ingredients” and substitute “sludge inoculum (6.7)”. In 9.1, in both definitions of symbol n after “gas” insert “in the given volume”. NOTETypographical errors. In Annex B, The title should read “cumulative” and not “cumulated”. Cross references. The Technical Commit
16、tee has reviewed the provisions of ISO 10634:1995 and of the draft of ISO/DIS 11923, to which normative reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A British Standard does not purport to include all the necessary provisions of a
17、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.
