Historical Standard: ASTM D6767-08 Standard Test Method for Pore Size Characteristics of Geotextiles by Capillary Flow Test
SUPERSEDED (see Active link, below)
ASTM D6767
1. Scope
1.1 This test method covers the determination of the pore size distribution of geotextile filters with pore sizes ranging from 1 to 500 ? m.
Note 1The accuracy of this procedure has been verified up to a maximum pore size of 200 ? m. Above this value accuracy has been found to be equipment dependent and should be verified by the user through checks on materials with known opening sizes.
1.2 The test method measures the entire pore size distribution in terms of a surface analysis of specified pore sizes in a geotextile, defined in terms of the limiting diameters.
1.3 The analyst should be aware that adequate collaborative data for bias statements as required by Practice D 2777 is not provided. See the precision and bias section for details.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 This standard may involve hazardous materials, operations, and equipment. 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.
