(Test Method)Standard Test Method for Sorbent Performance of Adsorbents for use on Crude Oil and Related Spills
Standard Test Method for Sorbent Performance of Adsorbents for use on Crude Oil and Related Spills
SIGNIFICANCE AND USE
5.1 This test method is to be used as a basis for comparison of adsorbents in a consistent manner.
5.2 These tests are not appropriate for absorbent materials that are covered in Methods F716.
Note 1: Ensure that material compatibilities exist between the sorbent and the hazardous substance which may be sorbed.
SCOPE
1.1 This test method covers laboratory tests that describe the performance of adsorbents in removing crude oils, 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 standard. No other units of measurement are included in this standard.
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 8.3.1.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3.1 General Terminology:
3.1.1 gellant—a material such as a colloidal network or other aggregate network that pervades and holds a liquid in a highly
viscous fragile structure. Many gels may rapidly liquify with added heat or ionic/polar addition. These materials are
soluble/flowable in excess liquid.
3.1.2 sorbent—an insoluble material or mixture of materials used to recover liquids through the mechanisms of absorption or
adsorption, or both.
3.1.3 thickener—a material (usually of higher molecular weight) that is soluble in excess liquid. These materials go from dry
to gummy (viscoelastic) to flowable and then soluble. The final viscosity depends only on the liquid to solid ratio.
3.1.4 universal sorbent—an insoluble material or mixture of materials that will sorb both hydrophobic and hydrophilic liquid
spills.
