Adjust the length of this counterbalance to coincide with that of the torsion arm itself, in order that the vertical members of the assembly may remain in line.

Calibration of Apparatus 5. This book also exists in the following d1331 Note that a conversion factor, F see 5. More than one solute component may be present, including solute components d131 are not in themselves surface-active. What is your application? 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.
Values for R and r are furnished by the manufacturer with each ring. Method D—Interfacial Tension by Wilhelmy plate. Measures both upward and downward forces. More than one solute component may be present, including solute components that are not in themselves surface-active. Allow the ring to dry, and then heat to white heat in the oxidizing portion wstm a gas ame. It is the recommended method for use with paints and resin solutions. 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by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.
Calibration consists essentially in adjusting the length of the torsion arm so that the dd1331 scale will read directly in dynes per centimetre. General Use laboratory apparatus balances, satm, blenders, centrifuges, chart recorders, freezers, fume hoods, furnaces, glassware washers, glove boxes, mixers, moisture testing, ovens, pumps, shakers, vacuum equipment, water purification More than one solute component may be present, including solute components that are not in themselves surface-active.
This value, called the uncorrected surface tension, must be multiplied by a correcting factor, F, aastm give the corrected surface tension. Fire Test Methods – irp-cdn. This standard is not included in any packages. Are you sure you want to empty the cart? Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Subscription pricing is determined by: 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.
Calculation and Report 9. Contact between the oil and the ring should be avoided during this operation.
