Updated Test Method Can Shorten Turbine Oil Production Time

To add flexibility to the time in which tests are run during the manufacture of lubricant oils, ASTM Standard D 665, Test Method for Rust-Preventing Characteristics of Inhibited Mineral Oil in the Presence of Water was updated by a section of Committee D02 on Petroleum Products and Lubricants.

“Many plants use this test as a production batch test and a shorter time will allow them to get their product out to the customer quicker,” said Mark Okazaki, chair of an ASTM D02 Section on Corrosion and Water/Air Separability, and a senior research chemist with Chevron Products Company, Richmond, Calif. “The previous edition was from 1998.”

As stated in its scope, D 665 is used to evaluate the ability of inhibited mineral oils, particularly steam-turbine oils, to aid in preventing the rusting of ferrous parts should water become mixed with the oil. This test method is also used for testing other oils, such as hydraulic oils and circulating oils. Provision is made in the procedure for testing heavier-than-water fluids.

The committee section that developed the revision represented lubricant oil manufacturers, lubricant oil additive suppliers, and lubricant oil test laboratories.

Those wishing further technical information on Test Method D 665 should contact Mark Okazaki, Chevron Products Company, 100 Chevron Way, Richmond, CA 94802-0627 (510/242-5978; fax: 510/242-3758). Committee D02 on Petroleum Products and Lubricants meets Dec. 3-8 in Nashville, Tenn. For meeting or membership information, contact Staff Manager David Bradley, ASTM (610/832-9681). //
