If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Surface and interfacial tension Technology. As the voice of the U. This instrument has, however, in addition to the torsion arm, sstm torsion-arm counterbalance.
ASTM D Standard Test Methods for Surface and Interfacial Tension
This includes hardness components in the water. The tensiometer shall be placed on a sturdy support that is free from vibrations and other distur1 These test methods are under the jurisdiction of ASTM Committee D01 on Paint and Related Coatings, Materials, d13331 Applications and are the direct responsibility of Subcommittee D This standard is also available to be included in Standards Subscriptions.
Preparation of Apparatus 4. Four methods are covered as follows:.
Pharmaceutical laboratory apparatus stability chambers, tablet disintegration, tablet dissolution, tablet hardness, V-blenders, The factor D can be measured by the usual procedures, and the value d can be obtained from published data.

Review them for hazards prior to usage. Petroleum Products and Biofuel lab apparatus baths, calorimeters, color measurement, density meters, flash point, hydrogenators, oil testing, penetrometers, surface tension, vapor pressure, viscometers and rheometers, Enter product namemake or model. Cenco Dunuoy Surface-Tension Tensiometer. Material Safety Data Sheets are available for reagents and materials. This value, called the uncorrected surface tension, must be multiplied by a correcting factor, F, to give the corrected surface tension.

Please first verify your email before subscribing to alerts. 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 measuring surface tension.
D d1313 Test Methods forSurface and Interfacial Tension of Solutions of SurfaceActive Agents1This standard is issued under the xed designation D; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. No other units of measurement are included in this standard.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Fiberon Decking – Progressive Engineering Inc? Four s1331 are covered as follows:.
Looking for a specific close-up? No further reproductions authorized. Calculation and Report 9. Values for R and r are furnished by the manufacturer with each ring. ASTM D standard test method for interfacial tension of Your Alert Profile lists the documents that will be monitored.
Nails, Spikes, and Staples. It must, therefore, be ascertained and applied.
In addition, surface tension data can predict interactions between liquids and solid ast, or other liquids and can be used to establish wetting properties of paints, solvents, and other liquids.
Two methods are covered as follows: NOTE 4Extreme care must be taken to have the sample vessel and platinum ring clean.
