ASTM D Standard Test Methods for Surface and Interfacial Tension
What is your application? You may delete a document from your Alert Profile at any time. It must, therefore, be ascertained and applied. This value for the correction factor is not valid for nonaqueous liquids, and should be used only where the solvent is preponderantly water. The factor D can be measured by the usual procedures, and the value d can be obtained from published data. Current edition approved June adtm, Make the measurement by turning the torsion wire counter-clockwise and simultaneously keeping the ring system in the zero atsm, as in the measurement of surface tension, until the ring breaks through the interface.
This standard is also available to be included in Standards Subscriptions. Request a Free Quote Right Now. Material Safety Data Sheets are available for reagents and materials. After allowing sufficient time for the interfacial tension to come to its equilibrium value Note 6make the measurement in the same manner as that used for aatm surface tension.
These simultaneous adjustments must be carefully proportioned so that qstm ring system remains constantly in its zero position.
Your Alert Profile lists the documents that will be monitored. This is particularly true when the solute is a surface-active material. Two methods are covered as follows: Review them for hazards prior to usage.
Referenced Documents purchase separately The documents listed below are e1331 within the subject standard but are not provided as part of the standard. More than one solute component may be present, including solute components that are not in themselves surface-active.
No other units of measurement are included in this standard. Remember me for one month. Historical Version s – view previous versions of standard. This value, called the uncorrected surface tension, must be multiplied by a correcting factor, X1331, to give the corrected surface tension. Petroleum Products and Biofuel lab apparatus baths, calorimeters, color measurement, density meters, flash point, hydrogenators, oil testing, penetrometers, surface tension, vapor pressure, viscometers dd1331 rheometers, 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.
Land Use and Development. Email Us or call toll-free: In addition, surface tension data can predict interactions between liquids and solid surfaces or other liquids and can be used to establish wetting properties of paints, solvents, and other liquids.
A superscript epsilon indicates an editorial change since the last revision or reapproval. The accuracy of this time observation may be indicated in the usual manner. Calibration consists essentially in adjusting the length asrm the torsion arm so that the dial scale will awtm directly in dynes per centimetre. A liquid level of the type employed on analytical balances may be used.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of aatm limitations prior to use.
ASTM D1331-11 Standard Test Methods for Surface and Interfacial Tension
Last previous edition approved in as D – 89 which was withdrawn January and reinstated in June In contrast to surface tension values, interfacial tension values cannot adequately be corrected for small temperature deviations by means of a simple formula.
Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market asfm and trade, and build consumer confidence.
