ASTM F726-06
(Test Method)Standard Test Method for Sorbent Performance of Adsorbents
Standard Test Method for Sorbent Performance of Adsorbents
SIGNIFICANCE AND USE
This test method is to be used as a basis for comparison of adsorbents in a consistent manner.
These tests are not appropriate for absorbent materials that are covered in Methods F 716.
SCOPE
1.1 This test method covers laboratory tests that describe the performance of adsorbents in removing nonemulsified oils and other floating, immiscible liquids from the surface of water.
1.2 The values stated in SI units are to be regarded as the standard.
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. Specific precautionary statements are given in 8.3.1.
