3. REQUIREMENTS

3.1 First article. When specified (see 6.1), a sample shall be subjected to first article inspection (see 6.2) in accordance with 4.2.

3.2 Standard sample. The finished glove and design shall match the standard sample (see 6.3) for shade and design and all other characteristics or acceptance criteria for which a standard sample is referenced.

3.3 Design. The Intermediate Cold Weather Glove is designed to be worn in cold weather environments to protect the user from the elements including snow, wind, and ice. The glove shall comply with the requirements listed in the below paragraphs.

The glove shall have a curved finger design (see Figures 3 & 4) and consist of the following: the outside shell shall be constructed from a water repellent stretch-woven nylon (see 3.4.1) and a water resistant leather palm (see 3.4.3). The glove shall have a waterproof breathable insert to stop moisture from being absorbed to the inside of the glove (see 3.4.6). The glove shall be insulated: the back of the hand/fingers shall have a siliconized lofted polyester insulation bonded to brushed tricot(see 3.4.4). The front of the hand/fingers (palm) lining shall be a nylon/polyester velour with a durable water repellent treatment (see 3.4.5) and it shall be laminated to the waterproof insert (see 3.4.6). The gauntlet shall not be insulated, but shall be lined with a nylon ripstop (see 3.4.2). The linings shall be the inner most layers of the glove.

The outside of the glove shall have a feature at the side seam that enables the gloves to be clipped together as a pair when not in use (see 3.4.11).

The palm side of the glove shall be designed as follows: the front of the hand/fingers, as well as the fourchettes, shall be constructed from leather (see 3.4.3). The gauntlet shall extend past the wrist and be elasticized at the inner wrist to provide stretch to accommodate varying wrist widths and provide for a closer fit (see 3.4.7). A pull loop shall be attached at the hem of the gauntlet to provide ease of donning as well as provide a means to attach the glove to other clothing items or equipment (see 3.4.10).

The back of the glove shall be designed as follows: the back hand shall be constructed from the stretch-woven nylon. (see 3.4.1). An additional strip of leather (see 3.4.3) shall be superimposed over the shell material at the knuckles to provide additional knuckle protection (see figure 1-4). The leather shall conform to the shape of the knuckles as shown in Figures 1-4.

A tab shall be attached at the inner side seam and be constructed from leather and loop tape, with its corresponding hook tape attached to the gauntlet (see 3.4.8 and 3.4.9). This hook and loop tape tab allows for an adjustable fit around the wrist at the bottom of the gauntlet. See Figures 1

– 4).

The glove shall have a label to identify the item, its size, and use and care instructions.

3.4 Materials and components. The materials and components shall conform to applicable specifications, standards, drawings, and patterns required herein.

3.4.1 Basic Shell Material. The cloth for the glove shall be a stretch-woven, 91% Nylon, 9% Spandex blend. The surface cloth shall be water repellent treated and shall conform to the requirements listed in Table I. The shade shall be coyote 498.

4.5 Examinations and tests.

4.5.1 Drying Time Test Method.

Apparatus and Materials:

Wringer (motor driven) (see notes) Laboratory balance, accurate to 0.01g White AATCC Textile Blotting Paper, 25 x 25 cm (see notes) Water, distilled 250 ml glass beaker

Test Specimens:

The fabric samples and blotting paper should be conditioned at 65 +/- 2% RH and 70 +/- 2ºF for a minimum of 4 hours.

3 test specimens per sample, 2 x 2 inches.

Procedure:

1. Test shall be run in standard conditions, 65 +/-2% RH and 70 +/- 2ºF.

2. Weigh the conditioned specimen using a laboratory balance accurate to 0.01g. A wire mesh kitchen/bathroom sink strainer may be used by placing it on the weighing pan of the lab balance in an inverted manner and taring its weight before the measurement of any specimen weight.

3. Place 100 mls of distilled water into a 250 ml glass beaker.

4. Submerge the specimen in the beaker of water for 30 minutes. Make certain that the specimen is completely submerged to insure complete wetting.

5. Remove the specimen and sandwich it between two pieces of unused blotting paper. Pass the sandwich through the wringer with a dead weight load of 27.7 +/- 0.5 kg.

6. Immediately place specimen on the balance with top door of the balance open, side doors closed and record wet weight either to the nearest 0.01 or 0.1 grams. (Degree of dryness shall be determined by the user.) Manually monitor weight at set intervals until dry or use an automated balance with capability to weigh specimen until dry (see notes). Record time to dry.

7. Repeat for remaining specimens. Average the 3 specimens.

Notes:

Blotting Paper see AATCC footnote 11.3.

4.5.2 Water Absorption Resistance Test. One 3-inch diameter specimen shall be tested from each 12 by 12 test area. Prior to testing, the specimen shall be allowed to reach moisture equilibrium in the standard conditions environment. 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. The specimen shall first be weighed (to the nearest 0.01 g) 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 deionized 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 in 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 reweigh the specimen to the nearest 0.01 g, and calculate the percent water absorption as follows:

Percent water absorption = ((W2 – W1) x 100) /W1

W1 = Original weight of conditioned specimen.

W2 = Weight of specimen after being subject to water.

4.5.3 Whole glove leak test. The finished glove shall be tested for leakage in accordance with 4.5.3.1, 4.5.3.2, and 4.5.3.3. The lot size shall be expressed in units of gloves. The sample unit shall be one glove, and the selection shall be by pairs. Any test failure shall be cause for rejection of the lot.

4.5.3.1 Testing apparatus. The test apparatus shall consist of a 3 inch inside diameter tubular rigid polyvinyl chloride test chamber approximately 12 inches in length. The chamber shall be capped approximately 2 inches from the bottom with the cap having a ½ inch diameter plastic air escape tube approximately 3 inches long. The test chamber shall be oriented vertically and placed in a container filled with approximately 1 inch of water such that the escape tube vents to the outside of the chamber, with the end of the tube under the water. The top of tube shall be beveled at a 45 degree angle on the inside. The top plug shall consist of polyethylene, approximately 4 inches in height, and 4 inches in diameter at the top tapering to approximately 2 inches in diameter at the bottom. An air passage shall be provided vertical through the plug and connected via nominal ½ inch tubing through a gage and air regulator to an oil-free compressed air source. A mechanism shall be provided that is capable of reproducibly clamping the plug into the end of the tube such that a seal is provided. An equivalent to the apparatus as mentioned above shall be qualified by US Army, Natick Soldier Center.

Note: The Whole Glove Leak Tester is covered by US Patent 4,776,209.

4.5.3.2 Testing procedure. The glove shall be inserted into the test chamber to near the cuff. The plug shall be inserted into the cuff of the glove and clamped such that a seal that holds not less than 4 psi is formed with the beveled edge of the test chamber.
