5、g AIR6130 Cadmium Plate Cyclic Corrosion Test RATIONALE Revision A: is made to provide a standard size for the bar called in Para 3 and to clarify the Test results. In Para 3. Change the test specimen size from 25.40 x 50.80 x 1.02 mm (1 by 2 by 0.040 inch) to 25.4 x 50.8 x 1.22 mm (1 by 2 by 0.048
6、inch) (see ASTM F1111) In para 6. “Total weight loss more than 0.0077g” is removed and the criteria will be 0.3mg/cm2. 1. SCOPE 14-day material test to determine the cyclic effects of runway deicing compounds on cadmium plated parts. 2. APPLICABLE DOCUMENTS The following publications form a part of
7、this document to the extent specified herein. The latest issue of SAE publications shall apply. The applicable issue of other publications shall be the issue in effect on the date of the purchase order.

TEST SPECIMEN PREPARATION Substrate: 4130 steel Size: 1 x 2 x 0.048 inch (25.
10、40 x 50.80 x 1.22 mm) (Specification ASTM F1111 Para 7) Finish: Cadmium plating: 0.0005” to 0.0008“ per side, do not exceed 0.0008 inch maximum plating (Method: Specification ASTM F1111 Para 7)( Quality: Specification SAE AMS-QQ-P-416 governs). There shall be no supplementary chromate treatment. a.
11、Three cadmium plated test specimens shall be used for each fluid to be tested. b. Sample of AMS1435 Runway Deicing Fluid shall be tested as received from the supplier. c. Sample of AMS1431 Runway Deicing Solid Compound shall be tested in a diluted form - diluted with ASTM D1193, Type IV, water to 15
12、% by weight solids. d. Procure soft flexible brushes for test (paintbrush type, 1.5 inches (3.8 cm) wide, with synthetic bristles approximately 1.5 inches (3.8 cm) long). 4. ENVIRONMENTAL EXPOSURE PREPARATION Preset humidity chamber to 90 F 5 F (32 C 3 C ) and 30 % 5% humidity. Affix plastic ties or
13、 other inert material as hangers (hangers shall be made from an inert material that will not react with the sample; plastic, plastic coated metals, monofilament fishing line, or stainless steels are acceptable) in the chamber to hold specimens during the environmental exposure period. Take the total
14、 area of the specimen as 27.67 cm2. The ratio of the area of immersed metal to volume of solution shall be 25 mL of solution per 625 mm2of specimen surface area. The volume corresponds to 110 mL. 5. TEST PROCEDURE a. Measure and record pH of solution to be tested (record to one decimal place, exampl
15、e: pH = 7.3). This value is to be included in the final test report. b. Solvent clean cadmium plated specimens with acetone; wipe gently with an acetone-soaked wiper. Without allowing the acetone to evaporate, gently remove excess acetone with a dry wiper. Allow samples to dry for 10 minutes in a de
16、siccator. Do not accelerate drying of samples with oven drying. NOTE: Care should be taken not to touch the cleaned specimen with bare hands; use stainless steel tweezers, clean gloves, or equivalent tool. c. Weigh and record initial specimen weights in grams. Record all weights throughout the test
17、to the nearest 0.0001 g. Return specimens to desiccator until Day 3. Test Schedule by Weekday MONDAY TUESDAY WEDNESDAY THURSDAY FRIDAY Friday Start - DAY 0 DAY 3 DAY 4 DAY 5 DAY 6 DAY 7 DAY 10 DAY 11 DAY 12 DAY 13 DAY 14 SAE INTERNATIONAL AIR6130A Page 3 of 4 d. FRIDAY START - Fill glass containers
18、with solution to be tested, one container for each coupon. Refer to 3b or 3c for solution being used (consider filling one extra container to have extra conditioned fluid available). Containers shall be large enough so the solution completely covers the specimens. Cover the container with loose fitt
