These simultaneous adjustments must be carefully proportioned so that the ring system remains constantly in its zero position. Four methods are covered as follows:. More than one solute component may be present, including solute components that are not in themselves surface-active.
If you like to setup a quick demo, let us know at support madcad. Measures both upward and downward forces. Land Use and Development. Print 1 2 3 4 5 asstm sstarting from page current page. Contamination of the liquid surface by dust or other atmospheric impurities during measurement should be avoided. Fiberon Decking – Progressive Engineering Inc?

ASTM D Standard Test Methods for Surface and Interfacial Tension
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn. Measurements made near or above the cloud point or other critical solubility points can be in serious error. For liquids of low surface tension, such as surfaceactive agents, F is, in general, appreciably less than unity.
Remember me for one month. Search book title Enter keywords for book title search. Fire Test Methods – irp-cdn.
Repeat the calibration procedure, readjusting the zero position after each change in the length of the torsion arm, until the dial reading agrees with the calculated value. This standard is not included in any aetm. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
More than one solute component may be present, including solute components that are not in themselves surface-active. Two methods are covered as follows: F is a function of the contours of the liquid surface in the neighborhood of the ring at the instant of breakaway.
Make the measurement by turning the torsion wire counter-clockwise and simultaneously keeping the ring system d3131 the zero position, as in the measurement of surface tension, ast, the ring breaks through the interface.
We have no amendments or corrections for this standard. 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.
Looking for a specific close-up? Report and adequately specify the nature of the nonaqueous liquid oil used in the determination.
There were no books found for the applied search filters. More than one solute component may be present, including solute components that are not in themselves surface-active. D 11ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. After allowing sufficient time for the interfacial d13311 to come to its equilibrium value Note 6make the measurement in the same manner as that used for measuring surface tension.
We have no document history for this standard. Surface and interfacial tension Technology.
ASTM D1331 – 14
The wire of the ring shall be in one plane, free of bends or irregularities, atsm circular. When set in the instrument, the plane of the ring shall be horizontal, that is, parallel to the surface plane of the liquid being tested.
