| Sl.No. | Synosis Points | |
| 1 | Scope: This standard specifies the requirements for the performance testing of membrane filters used for the retention followed by direct enumeration of microorganisms by culture methods. | |
| 2 | This standard is applicable to membrane filters which are used for retention followed by direct enumeration of specific microorganisms on solid media or on other devices containing media, like absorbent pads. | |
| 3 | This standard is not applicable for membrane filters used for concentration and elution or for qualitative methods. These tests are applicable to the membrane filters intended for the microbiological analysis of different types of water, such as: — drinking water, bottled water and other types of water with expected low numbers of microorganisms; — water with expected higher numbers of microorganisms, for example, surface water and process water. | |
| 4 | This standard applies to: — manufacturers producing membrane filters; — microbiological laboratories using membrane filters for their own testing or providing these to other end users. | |
| 5 | The standard also specifies normative references, definitions, principle, apparatus and glassware, culture media and diluents, preparation of micro-organisms for performance testing, sampling of membrane filters for testing, procedure, calculation, expression and interpretation of results and documentation of test results. | |
