【国外标准】 Standard Guide for Total Immersion Corrosion Test for Soak Tank Metal Cleaners (Withdrawn 2023)

3.1 This guide is used to distinguish soak tank metal cleaners that are excessively corrosive to metals (other than aluminum and its alloys which are covered by Method D930). The users will define the degree of corrosion considered excessive, in terms of weight loss per unit of surface area or in terms of changes in appearance, or both.1.1 This guide covers determination of the corrosive effects of soak tank metal cleaners on all metals other than aluminum and its alloys, under conditions of total immersion, by quantitative measurement of weight change or by qualitative visual determination of change. The test determines the effects of the cleaner on metals being cleaned, and does not determine the life of the cleaner or of the containing equipment.1.2 When the test is used to assist in the choice of material for a specific use, the test conditions should simulate the conditions of use as closely as practicable.1.3 Where no further processing subsequent to cleaning is indicated, a test for the effect of residual cleaner on the corrosion behavior of the material may be required.1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.1.5 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.
