ASTM D930-89(1996)e1

Standard Test Method of Total Immersion Corrosion Test of Water-Soluble Aluminum Cleaners (Withdrawn 2001)

SCOPE
1.1 This test method  covers determination of the corrosive effects of water-soluble aluminum cleaners (nonetching type) on aluminum or aluminum alloys, under conditions of total immersion, by quantitative measurement of weight change or by qualitative visual determination of change. The test is designed for the determination of corrosion characteristics of the cleaner and not for determination of the life of the cleaner.  
1.2 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. Material Safety Data Sheets are available for reagents and materials. Review them for hazards prior to usage.
