AMIL performs most of the effect on aircraft materials tests as described in SAE aerospace material specifications AMS1424, AMS1428, AMS1431 and AMS1435. The tests are described below:

 

Sandwich Corrosion (SC)

The Sandwich Corrosion test is performed according to standard ASTM F1110. SC is an accelerated environmental corrosion test of liquid or solid materials that occurs between faying surfaces of structural aluminum alloys commonly used in aerospace construction.

 

Total Immersion Corrosion (TIC)

The Total Immersion Corrosion test is performed according to standard ASTM F483. TIC covers the determination of the corrosiveness of aircraft maintenance chemicals on aircraft metals over time, under conditions of total immersion by a combination of weight-change measurements and visual qualitative determination.

 

Low Embrittling Cadmium Plate (LECP)

The Low Embrittling Cadmium Plate test is performed according to ASTM F1111. The LECP covers the determination of the corrosiveness of aircraft maintenance chemicals on low embrittling cadmium plating used on aircraft high-strength steel under conditions of total immersion by a combination of weight-change measurements and visual qualitative determination.

 

Cadmium Plate Cyclic Corrosion (CPCC)

The Cadmium Plate Cyclic Corrosion test is performed according to AIR 6130. The CPCC test consists of a 14-day cycling test where low embrittling cadmium plating used on aircraft high-strength steel coupons are subjected to runway deicing liquid and solid compounds.

 

Effect on Transparent Plastics (ETP)

The Effect on Transparent Plastics test is performed according to ASTM F484. The ETP test method covers the determination of the crazing effect that a liquid or semi-liquid test compound will have on transparent acrylic and polycarbonate plastic materials under bending stress.

 

Effect on Unpainted Surfaces (EUS)

The Effect on Unpainted Surfaces test is performed according to ASTM F485. The EUS test method covers the determination of the effect of fluids over unpainted aircraft surfaces.

 

Runway Concrete Scaling Resistance (RCSR)

The Runway Concrete Scaling Resistance test is performed according to ASTM C672. The RSCR test method covers the determination of the resistance to scaling of a horizontal concrete surface exposed to freezing-and-thawing cycles in the presence of deicing chemicals.

 

Rinsibility (RIN)

The Rinsability test is performed according to Section 3.2.9 of AMS 1435. The RIN test is performed over clear glass panels.

 

Effect on Carbon Brake Systems (CCBDO)

This test method is designed to assess the relative effect of runway deicing chemicals on carbon brake systems by measuring the mass change of contaminated carbon brake anti-oxidant (AO) coated coupons when submitted to catalytic oxidation at high temperature, in accordance with the AIR5567 test method.
