ASTM F1864-21(Test Method)
Standard Test Method for Dust Erosion Resistance of Optical and Infrared Transparent Materials and Coatings

SIGNIFICANCE AND USE
5.1 All materials on exterior aircraft surfaces are subject to abrasion from airborne particles of various sizes and shapes. Transparent materials are particularly vulnerable to abrasion, since their performance is based on their ability to transmit light with a minimal amount of scatter. Scratches, pitting, and coating removal and delamination as a result of abrasion may increase scatter, reduce transmission, and degrade the performance of transparent materials. Visually transparent materials are required for pilot and air crew enclosures, such as canopies, windshields, and viewpoints. Materials transparent in the IR region (8 to 12 μm) are required for tracking, targeting, and navigational instrumentation.  
5.2 This test method is intended to provide a calibrated and repeatable means of determining the relative abrasion resistance of materials and coatings for optical and IR transparent materials and coatings. The test parameters for this test method can be directly related to dust cloud densities and velocities to which transparent materials are exposed in the field.
SCOPE
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.

Standard Test Method for Abrasion Resistance of Hard Anodic Coatings by a Taber-Type Abraser

SIGNIFICANCE AND USE
5.1 Hard anodic oxidation coatings are often used to obtain improved resistance to abrasion, and have been used in such applications as valves, sliding parts, hinge mechanisms, cams, gears, swivel joints, pistons, insulation plates, blast shields, etc.  
5.2 This abrasion resistance test method may be useful for acceptance testing of a hard anodic coating, and it can be used to evaluate the effects of processing variables such as substrate preparation before coating, surface texture, coating technique variables, and post coating treatments.  
5.3 Results may be used for process control, comparative ranking, or to correlate with end-use performance. The resistance of material surfaces to abrasion, as measured on a testing machine in the laboratory, is generally only one of several factors contributing to wear performance as experienced in the actual use of the material. Other factors may need to be considered in any calculation of predicted life from specific abrasion data.  
5.4 The properties and characteristics of hard anodic oxidation coatings are significantly affected by both the alloy and the method of production.
Note 2: Hard anodizing will usually result in a dimensional increase on each surface equal to about 50 % of the coating thickness. Normal thickness for wear applications tends to be 40 µm to 60 µm; however the thickness of anodized coatings often ranges between 8 µm to 150 µm.  
5.5 The resistance of hard anodic coatings to abrasion may be affected by factors including test conditions, type of abradant, pressure between the specimen and abradant, composition of the alloy, thickness of the coating, and the conditions of anodizing or sealing, or both.
Note 3: The resistance to abrasion is generally measured on unsealed anodic oxidation coatings. While corrosion resistance is often increased by sealing the coating, it has been observed that sealing or dyeing can reduce the resistance to abrasion by over 50 %.  
5.6 The outer surface of the anod...
SCOPE
1.1 This test method quantifies the abrasion resistance of electrolytically formed hard anodic oxidation coatings on a plane, rigid surface of aluminum or aluminum alloy.  
1.2 This test uses a Taber-type abraser,2 which generates a combination of rolling and rubbing to cause wear to the coating surface. Wear is quantified as cumulative mass loss or loss in mass per thousand cycles of abrasion.  
1.3 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
Note 1: The procedure described in Method A is similar to MIL-PRF-8625 (paragraph 4.5.5) and SAE AMS 2469 (paragraph 3.3.4). The procedure described in Method B includes a break-in period of 1000 cycles and is similar to ISO 10074 Annex B. When no procedure is specified, Method A shall be the default procedure. Although the procedures described in this method may be similar, they are not equivalent to Specification B893 or Test Method D4060.  
1.4 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.  
1.5 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.

Standard Practice for Sampling for Particulate Contamination by Tape Lift

SIGNIFICANCE AND USE
3.1 The tape lift provides a rapid and simple technique for removing particles from a surface and determining their number and size distribution.  
3.2 By using statistically determined sample size and locations, an estimate of the surface cleanliness level of large areas can be made. The user shall define the sampling plan.  
3.3 The sampling plan shall consider the importance of surface geometry and surface orientation to gas flow, gravity, obstructions, and previous history of hardware. These factors influence particle fallout and entrapment of particles on the surface. The geometry of joints, recessed areas, fasteners, and the correspondence of particle-count data to area can be maintained.  
3.4 The selection of tape and the verification of its effect on the cleanliness of the hardware is very important. The tape adhesive should have sufficient cohesion to avoid transfer of the adhesive to the surface under test. The impact of adhesive transfer should be evaluated by laboratory testing before using the tape on the hardware. Since potential for adhesive transfer exists, cleaning to remove any adhesive might be required. In addition, the tape should have low outgassing characteristics, and as a minimum, it should meet the requirements of less than 1.0 % total mass loss (TML) and 0.1 % collected volatile condensable materials (CVCM), as measured by Test Method E595.  
3.5 Care should be exercised in deciding which surfaces should be tested by this practice. The tape can remove marginally adhering paint and coatings. Optical surfaces should not be tested until verification has been made that the surface coating will not be damaged. The minimum effectiveness of particle removal from smooth surfaces and angles down to 90° for all practice methods is 90 % for particles larger than 5 μm. Rough surface finishes result in low removal efficiencies. Surface finishes up to approximately 3.20 μm (125 μin.) have been tested and found to give satisfactory results.  
3.6 T...
SCOPE
1.1 This practice covers procedures for sampling surfaces to determine the presence of particulate contamination, 5 μm and larger. The practice consists of the application of a pressure-sensitive tape to the surface followed by the removal of particulate contamination with the removal of the tape. The tape with the adhering particles is then mounted on counting slides. Counting and measuring of particles is done by standard techniques.  
1.2 This practice describes the materials and equipment required to perform sampling of surfaces for particle counting and sizing.  
1.3 The criteria for acceptance or rejection of a part for conformance to surface cleanliness level requirements shall be determined by the user and are not included in this practice.  
1.4 This practice is for use on surfaces that are not damaged by the application of adhesive tape. The use of this practice on any surface of any material not previously tested, or for which the susceptibility to damage is unknown, is not recommended. In general, metals, metal plating, and oxide coatings will not be damaged. Application to painted, vapor deposited, and optical coatings should be evaluated before implementing this test.  
1.5 This practice provides three methods to evaluate tape lift tests, as follows:
Practice  
Sections  
A—This method uses light transmitted through the tape and tape adhesive to detect particles that adhere to it.  
4 to 6  
B—This method uses light transmitted through the tape adhesive after bonding to a base microscope slide, dissolving the tape backing, and a cover slide. The particles are embedded in the adhesive, and air bubbles are eliminated with acrylic mounting media.  
7 to 9  
C—This method uses light reflected off the tape adhesive to detect particles that adhere to it.  
10 to 12
