Current edition approved June 1, Need more than one copy? In contrast to surface tension values, interfacial tension values cannot adequately be corrected for small temperature deviations by means of a simple formula. Review them for hazards prior to usage. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not v1331 as part of the standard. Measures both upward and downward forces. In most cases an accuracy of 65 s is reasonable, and sufficient for this test method.
Material Safety Data Sheets are available for reagents and materials. Care should be taken that the solution is physically homogeneous.

This standard is not included in any packages. This is particularly true when the solute is a surface-active material. As the breaking point is approached, the adjustments must be made more carefully and more slowly.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of asmt rights, are entirely their own responsibility. To calculate M, multiply the tensiometer dial reading by the factor which converts this reading into grams pull on the ring, as calculated in 5.

Calibration of Apparatus 5. Record the dial reading to 0. Place the level on the table that holds the sample for testing, and adjust the leg screws of the tensiometer until the table is horizontal. It must, therefore, be ascertained and applied.
ASTM D1331 – 14
NOTE 5Since the surface tension of a solution is a function of the concentration, care must be taken that the concentration is adjusted and recorded within known limits. Material Safety Data Sheets are available for reagents d13331 materials.
More than one solute component may be present, including solute components that are not in themselves surface-active. Last previous edition approved in as D aatm 89 which was withdrawn January and reinstated in June For liquids of low surface tension, such as surfaceactive agents, F is, in general, appreciably less than unity.
