(Test Method)Standard Test Method for Total Immersion Corrosion Test for Aircraft Maintenance Chemicals
Standard Test Method for Total Immersion Corrosion Test for Aircraft Maintenance Chemicals
SIGNIFICANCE AND USE
Many aircraft maintenance chemicals are used on components and structures which would be adversely affected by excessive dimensional change. This test method screens these chemicals to ensure compliance with specified weight change criteria.
SCOPE
1.1 This test method covers the determination of the corrosiveness of aircraft maintenance chemicals on aircraft metals with time under conditions of total immersion by a combination of weight change measurements and visual qualitative determination of change.
1.2 The values stated in SI units are to be regarded as standard. The values in parentheses are for information only.
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.

criteria.
4. Apparatus
4.1 Wide-Mouth Sealable Glass Jar or Stoppered Flask of Suitable Size—The glass jar or flask should be so chosen so that the
specimens will remain fully immersed in a vertical position during testing and the ratio of area of immersed metal to volume of
solution will be in accordance with 8.1.
4.1.1 Warning—Some aircraft maintenance chemicals when heated have high vapor pressures or may produce gases during
testing. Suitable precautions should be taken to prevent the containing vessel from exploding or the vessel should be so chosen
as to withstand the resulting pressure.
4.2 Specimen-Supporting Device—A glass ofor fluorocarbon plastic supporting system designed to keep the specimen fully
immersed while ensuring free contact with the solution, and designed to isolate the specimens from each other physically.
4.3 For materials containing low boiling point solvents, a means of preventing evaporation losses shall be used.
4.4 Constant-Temperature Device—Any suitable regulated heating device (mantle, hot plate, or bath) may be used to maintain
the solution at the required temperature.
