ASTM F1864-21 - Standard Test Method for Dust Erosion Resistance of Optical and Infrared Transparent Materials and Coatings
Standard Test Method for Dust Erosion Resistance of Optical and Infrared Transparent Materials and Coatings
|Keywords:||abrasion; dust erosion; IR window; transparent material ;|
1.1 This test method covers the resistance of transparent plastics and coatings used in aerospace windscreens, canopies, and viewports to surface erosion as a result of dust impingement. This test method simulates flight through a defined particle cloud environment by means of independent control of particle size, velocity, impact angle, mass loading, and test duration.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
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.
