With liquids heavier than water, where the ring must be pushed downward, the interfacial tensiometer should be used. There were no books found for the applied search filters.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Review them for hazards prior to usage. The presence of solutes other than the surface-active agent should be ascertained and reported qualitatively and quantitatively, insofar as possible. For liquids of low surface tension, such as surfaceactive agents, D1313 is, in general, appreciably less than unity.

Your Alert Profile lists the documents that will be monitored. Values of F in5. As the breaking point is approached, the adjustments must be made more carefully and more slowly.
Additional measurements shall be made if indicated by the over-all variation obtained, the total number of readings to be determined by the magnitude of that variation.
This instrument has, however, astmm addition to the torsion arm, a torsion-arm counterbalance. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. A superscript epsilon indicates an editorial change since the last revision or reapproval.
