ASTM D3705 Test Method for Misting Properties of Lubricating Fluids
3. Summary of Test Method
3.1 The mist generator is charged with oil and installed in the mist system. The unit is operated for 19 h; the mist generator, line condensate bottles, and reclassified oil collector are weighed before and after the test. The output from the generator and percentages of reclassified oil, line condensate, and stray mist are determined from changes in weight.
NOTE 2 - Line condensate is the commonly accepted term used to describe the oil that coalesces in the mist distribution lines. In this test, the oil that coalesces in the 38-mm (1 1/2-in.) tubing and the diagonal 19-mm (3/4-in.) tubing is collected and weighed as line condensate. Oil that coalesces in the vertical 19-mm (3/4-in.) tubing becomes part of the reclassified oil.
4. Significance and Use
4.1 This test provides a guide for evaluating the misting characteristics of oils for use in industrial mist lubrication systems. The degree of correlation between this test and service performance has not been fully determined.
