Sandwich Corrosion Test: Specimen preparation, testing, and interpretation shall be in accordance with ASTM F1110 using the following materials and with the following exceptions:
Reagents and materials exception:
(1). Clad 7075-T6 aluminum alloy in accordance with QQ-A-250/13 (AMS 4049 or AMS-QQ-A-250/13 optional) (2024-T3 Alclad specimens are neither required nor optional.)
(2) Bare 7075-T6 aluminum alloy in accordance with QQ-A-250/12 (AMS 4045 or AMS-Q-A-250/12 optional) anodized in accordance with BAG 5019 or MIL A-8625, Type I.
(3) Anodize shall be sealed. (2024-T3 nonclad specimens are neither required nor optional). ·
(4) Distilled or deionized water may be used in place of ASTM F1193, Type IV reagent grade water for control specimens.
(5) The filter paper may be Whatman No. 5 or equivalent in place of Whatman GFA glass fiber paper.
(1) The filter paper strips shall be 1 by 3 inches and shall be placed in the center of the sandwiched specimens.
(2) Each sandwich specimen shall be held together with waterproof tape, with no more than 1 piece of tape (maximum width 0.75 inch) on each of two opposite edges.
Interpretation of result exceptions:
(1) Leaching or lightening of the chromate sealed anodize coating shall not be cause for rejection.
(2) Deposits or residues from the material being tested that are not products of corrosion of the test panel surface shall not be cause for rejection.
(3) Special procedure for evaluation of fire extinguishing foams and liquids.
Panels with very light darkening or staining, which have no obvious metal attack or pitting, may be swabbed (cotton-tipped swabs or cotton gauze) with a 0.26 mole/liter sulfuric acid solution and re-examined. If the coloration is substantially removed and there is no evidence of metal attack or pitting, the condition shall not be cause for rejection. (The 0.26 mole/liter sulfuric acid solution can be prepared by adding 1.5 cc of concentrated sulfuric acid (SG = 1.84) to 100 cc of distilled or deionized water.
(4) Panels shall have a rating of 1 (no more than 5 percent of the surface area shall be corroded) or better in accordance with ASTM F 1110. The preferred method of determining the corroded area is by using image analysis. Other means approved by the purchaser may be substituted.
(5) Any corrosion in excess of that shown by the control group shall be cause for rejection.
Sandwich Corrosion Test: continued
Acrylic Crazing Test:
The material being tested shall not craze, crack, or etch acrylic test specimens when tested in accordance with ASTM F 484 using Type C (stretched acrylic plastic in accordance with MIL-P-25690) stressed to an outer fiber stress of 4500 psi.
Type C (MIL-P-25690): No crazing, cracking, or etching
Paint Softening Test Procedure:
a. Testing shall be in accordance with ASTM F502 using the following coating systems.
(1) BMS 10-79, Type II primer applied in accordance with BAC5882 plus BMS 10-60, Type II enamel in accordance with BAC5845.
(2) BMS 10-79, Type Ill primer applied in accordance with BAC5882, plus BMS 10-100 coating in accordance with BAC5797.
b. Three specimens conforming to Section 12a.(1) and three specimens conforming to Section 12a(2) shall be used for each test condition.
c. The material being tested shall not produce a decrease in film hardness greater than two pencils, or any discoloration or staining.
NOTE: Slight darkening of the BMS 10-100 surface is acceptable.
*Paint system 1: _Q_ pencil hardness change after 24 hour post-exposure dry time.
No discoloration or staining.
*Paint system 2: .Jl… pencil hardness change after 24 hour post-exposure dry time.
No discoloration or staining.
*Product leaves an oily residue that does not rinse off but does wipe away
