5.1?The data generated by this test method shall be used to determine whether aircraft structural aluminum alloys are liable to be corroded or damaged by application of the test material during routine maintenance operations. 5.2?Interpretation of the sandwich corrosion test results is based on a comparison of the appearance of faying surfaces of three sets of coupons. One set of test coupons is exposed with reagent water only in the faying surfaces, to establish the baseline (controls) against which the panels exposed to the test material are compared. Disregard corrosion at cut edges of the test coupons. 5.3?The relative corrosion severity rating system is provided in order to allow a numerical classification of the test results and to eliminate the necessity for elaborate weight loss measurements. Pitting corrosion, which is rated 4extensive (severe) corrosion, may involve only a negligible weight loss. 5.4?Relative corrosion severity rating system:
1.1?This
test method defines the procedure for evaluating the corrosivity of
aircraft maintenance chemicals, when present between faying
surfaces (sandwich) of aluminum alloys commonly used for aircraft
structures. This test method is intended to be used in the
qualification and approval of compounds employed in aircraft
maintenance operations.
1.2?The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information. 1.3?This standard may involve hazardous materials, operations, and equipment. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
