13、06:30:16 MDTNo reproduction or networking permitted without license from IHS -,-,- ISO 14442:2006(E) iv ISO 2006 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing Int
14、ernational Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison w
15、ith ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of techni
16、cal committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn
17、to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14442 was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 5, Biological methods. This sec
18、ond edition cancels and replaces the first edition (ISO 14442:1999), which has been technically revised.

20、nal Standard should be familiar with normal laboratory practice. This International Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance wit
21、h any national regulatory conditions. IMPORTANT It is absolutely essential that tests conducted according to this standard be carried out by suitably trained staff. 1 Scope This International Standard provides procedures, not covered by the methods described in ISO 8692 and ISO 10253, for testing di
22、fficult substances for inhibition of algal growth. The main subjects covered by the guideline are the methods for preparing the test substance for testing and the procedures needed to carry out an appropriate test. The following test substances are covered by this guideline: a) poorly soluble pure o
23、rganic compounds; b) poorly soluble mixtures of organic substances; c) poorly soluble inorganic materials; d) volatile substances; e) waste waters and environmental samples containing water and sediments; f) coloured and/or turbid samples; g) compounds of heavy metals. The following methods of addit
24、ion are covered: direct; dispersion; water-soluble and water-accommodated fractions. Some guidelines related to the analytical procedures and to the interpretation of the results have been included. References to documents describing the background for the testing of difficult substances are given i
