100 (+ 20) foot candles, and shall be a good match to the standard sample under incandescent lamplight at 2856 (+ 200) °K (see 6.4).

4.5 Methods of inspection.

4.5.1 Stiffness test.

a) Degree of Stiffness before soaking. Tested according to ASTM D 2821 except the specimens shall be pre-flexed as follows:

1. Loosen knob (G). Using knob (H) slowly rotate the top dial (K) in a counterclockwise direction until the specimen clamp indicator (I) shows that the specimen has been twisted 90°. Use a uniform rate of rotation that will take 4 to

5 seconds to twist the specimen through 90°.

2. Reverse rotation to the clockwise direction and continue rotating slowly until the specimen clamp indicator (I) has passed the original reference line indicated on the lower dial (J) by approximately 45°. Again reverse the direction of rotation and slowly realign the specimen clamp indicator (I) with the original reference line indicated on the lower dial (J).

3. Lock top dial (K) by turning knob (G) until tight, then reset dial (K) to read 270°.

4. Repeat the flexing operation by following steps 1, 2, and 3. When the second flexing cycle is completed, loosen knob (G), turn upper dial (K) slowly (4 to 5 seconds for 90° rotation) in a counterclockwise direction, using knob (H) until the specimen clamp indicator (I) shows 90° twist. Read the angle of torsion from the upper dial (K) and record the value to the nearest 5 degrees. The angle of torsion of each specimen shall be reported to the nearest 5 degrees.

b) Degree of stiffness after soaking. If the stiffness requirements specified for before soaking are not met, then do not test for stiffness after soaking. Any individual specimen exceeding the maximum stiffness values specified for before soaking shall not be tested for stiffness after soaking. The specimens shall be immersed in 1,000 mL of distilled water at 140

F (+ 5) F for 20 hours (+ 2) hours. Complete immersion of the specimens shall be accomplished by placing a floating cover on the vessel used for the immersion of the specimens.

After the required immersion period, the specimens shall be removed from the water and reconditioned in accordance with standard atmospheric conditions as specified in ASTM D 1610.

The reconditioned specimens shall be placed flesh side down on a rule graduated in decimal inches and the distance between the bench marks shall be measured to the nearest 0.05-inch. If the distance is 3.4 to 3.6 inches, test the specimen in accordance with ASTM D 2821 and the following exceptions.

If the distance is 3.2 inches or less, the specimen shall be reported as a test failure. If the distance between benchmarks is 3.25 to 3.35 inches, the specimen shall be stretched before testing. To stretch the specimen, place the specimen on the rule and align one of the benchmarks with a division line on the rule. Hold the specimen against the rule by placing the fingertip of one hand on the aligned benchmark. With the thumb and index finger of the other hand, lightly grip the specimen near the aligned bench mark, then slide the finger and thumb along the specimen to the other bench mark while exerting pressure on the specimen that is sufficient to obtain the required distance between the bench marks. If the required distance between the benchmarks has been obtained (3.4 inches to 3.6 inches), test the specimen in accordance with

ASTM D 2821 and the exceptions starting at 4.6.1 a) section 3. If the distance between the benchmarks is greater than 3.6 inches discard the specimen and test a new specimen selected from the same 12 by 12 inch test sample of leather from which the discarded specimen was obtained. The new specimen shall be tested for stiffness before and after soaking. The test results obtained when the discarded specimen was tested for stiffness before soaking shall not be reported.

4.5.2 Water absorption resistance test. One 3-inch diameter specimen shall be tested from each 12 by 12 inch test area. Prior to testing, the specimen shall be allowed to reach moisture equilibrium in accordance with ASTM D 1610. A stainless steel 500 mL, 3-inch diameter, 5-inch long container with a rubber gasket and cover shall be used to test the specimen (See 6.5).

The specimen shall first be weighed (to the nearest 0.01 gram) and then shall be placed inside the cover with the flesh side of the specimen next to the inside of the cover. Place the rubber gasket inside the cover and against the grain surface of the leather specimen. Add 100 mL of distilled or de-ionized water at 23 C to the container. Secure the cover with the specimen and gasket to the container. Invert the container so the water is against the grain surface of the specimen.

Place the inverted container on a flat surface and allow it to remain in the inverted position for

30 minutes. At the end of 30 minutes place the container upright, remove the cover, and place it on a flat surface. The inside of the cover shall face the flat surface. Tilt the cover so the outer edge of the bottom is raised 1-1.5 inches from the flat surface, and allow it to drain for 5 minutes.

After 5 minutes immediately remove the specimen from the cover, hold the specimen by its edge and shake briskly once to remove any free moisture from the surface of the specimen.

Immediately re-weigh the specimen to the nearest 0.01 grams, and calculate the percent water absorption as follows:

Percent water absorption = (W 2 - W 1) x 100

W 1

Where:

W1 = Original weight of conditioned specimen

W2 = Weight of specimen after being subject to water

4.5.3 Oil absorption resistance test. One 4 by 4 inch test specimen shall be tested from each

12 by 12 inch test area. Place the specimen on a horizontal flat surface flesh side up. With a dropping bottle pipette, carefully place (do not drop) three small (approximately 3/16 inch diameter or 0.05 mL volume per drop) of Nujol (see 6.12) mineral oil on the flesh surface of the specimen. Each drop shall be in a different location. After 5 minutes immediately observe the drops from an angle of approximately 45 for evidence of penetration of the oil into the leather at the oil-leather interface or wicking of the oil into the leather at the edges of the drops. The mineral oil shall have a say bolt viscosity of 360-390 at 100F specific gravity of 0.880/0.900 at

60F.

4.6 Toxicity documents. All finishes/chemicals used to process the gloves shall be identified and accompanied by the appropriate Material Safety Data Sheet (MSDS) information. The use of chemicals recognized by the Environmental Protection Agency (EPA) as human carcinogens is prohibited.

5. PACKAGING

5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When actual packaging of material is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain requisite packaging requirements. Packaging requirements are maintained by the

Inventory Control Point’s packaging activities within the Military Department or Defense

Agency, or within the military service’s system commands. Packaging data retrieval is available from the managing Military Department’s or Defense Agency’s automated packaging files, CD-

ROM products, or by contacting the responsible packaging activity.
