1 | Scope: This standard specifies a method for the detection and enumeration of somatic coliphages by incubating the sample with an appropriate host strain. The method is applicable to all kinds of water, sediments and sludge extracts, where necessary after dilution. The method is also applicable to shellfish extracts. | |
2 | In the case of low phage numbers, a preconcentration step may be necessary for which a separate International Standard will be developed. | |
3 | The standard also specifies normative references, terms and definitions, safety precautions, principle, diluents, culture media and reagents, apparatus and glassware, microbiological reference cultures, sampling, preparation of test material, procedure, expression of results and test results. |
