ASTM F3440-21 PDF

Scope: 1.1 This test method is intended as a means of determining the corrosive effects of aircraft maintenance chemicals on low-embrittling zinc-nickel plating used on aircraft highstrength steel, under conditions of total immersion by quantitative measurements of weight change. Aircraft maintenance chemicals requiring this test method shall be determined by the cognizant engineering authority. 1.2 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. For specific hazard statements, see Section 6 and 4.1. 1.3 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.
