Scope

1.1 This practice covers the evaluation of atmospheric galvanic corrosion of any materials that can be made into washers.

1.2 The washer, or disk, test was used by H. O. teeple in 1949 for a series of exposures for ASTM Committee B03.08 on Corrosion of Non-Ferrous Metals and Alloys. Since that time, ASTM has refined the test and conducted other investigations using this practice.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
