1. Scope | ||
1.1 These test methods cover the determination of surface tension and interfacial tension of solutions of surface-active agents, as defined in Terminology D 459. Two methods are covered as follows: Method A—Surface Tension. Method B—Interfacial Tension. 1.2 Method A is written primarily to cover aqueous solutions of surface-active agents, but is also applicable to nonaqueous solutions and mixed solvent solutions. 1.3 Method B is applicable to two-phase solutions. More than one solute component may be present, including solute components that are not in themselves surface-active. 1.4 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. Material Safety Data Sheets are available for reagents and materials. Review them for hazards prior to usage. |
