Historical Standard: ASTM D1987-95(2002) Standard Test Method for Biological Clogging of Geotextile or Soil/Geotextile Filters
SUPERSEDED (see Active link, below)
ASTM D1987
1. Scope
1.1 This test method is used to determine the potential for, and relative degree of, biological growth which can accumulate on geotextile or geotextile/soil filters.
1.2 This test method uses the measurement of flow rates over an extended period of time to determine the amount of clogging.
1.3 This test method can be adapted for nonsaturated as well as saturated conditions.
1.4 This test method can use constant head or falling head measurement techniques.
1.5 This test method can also be used to give an indication as to the possibility of backflushing and/or biocide treatment for remediation purposes if biological clogging does occur.
1.6 The values in SI units are to be regarded as the standard. The values provided in inch-pound units are for information only.
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
