| Organization: | NEN |
| Publication Date: | 1 November 1992 |
| Status: | inactive |
| ICS Code (Examination of physical properties of water): | 13.060.60 |
scope:
This Standard describes the determination of suspended solids in surface and ground waters by filtration through filters with a pore width of 0,4 to 0,45 µm. The lower limit of the determination is 1 mg/l. The standard is not applicable to effluents and waste waters. Water samples are not always stable which means that the content of suspended solids depends upon storage time, means of transportation, pH value and other circumstances. Results obtained with unstable samples should be interpreted with caution.
