3.4 Design. The ICWG is designed to be worn in cold weather environments to protect the user from the elements. The glove shall consist of an outside shell constructed from a three-layer laminate consisting of a nylon taslan face backed by a waterproof layer and lightweight knit lining in accordance with MIL-DTL-32698. The shell shall include a water-repellant treatment on the face, conforming to 3.5.1, and water-repellent goatskin leather conforming to 3.5.2. The leather used on the palm, thumb, and back of the first finger shall be backed by the waterproof material. The fourchettes shall also be constructed from the leather, and an additional strip of leather shall be superimposed over the shell at the knuckles to provide added protection. The suede side of the leather shall be used to construct a “nose wipe” on the back of the thumb, and a patch that shall be superimposed over the thumb crotch for added durability. The glove shall be insulated on the back of the hand and thumb, with the insulation material conforming to 3.5.5. The full inside lining shall be constructed from napped wool, conforming to 3.5.3;

this inside lining shall be tacked to the shell at several locations, to include each fingertip, to ensure the lining material does not separate from the shell. The gauntlet shall be lined with 70 denier nylon ripstop, conforming to

MIL-DTL-32699, and have an attached inside cuff, conforming to 3.5.6. The glove shall have a curved finger design, an elasticized inner wrist and an adjustable strap at the back of the wrist to provide a close fit, with a long gauntlet that shall extend up the forearm with a manual adjustment feature at the hem to provide desired closure over various clothing layers. The outside of the shell shall have a feature at the side seam that enables the gloves to be clipped together as a pair when not in use (see 3.5.14). The shell shall have a label to identify the item, its size, and use and care. (See figures 1 through 4).

3.4.1 Figures. Figures 1 through 4 are furnished for informational purposes only. To the extent an inconsistency exists between the written specification and the figures, the written specification shall govern.

3.5 Materials and components.

3.5.1 Basic shell material. The cloth used to construct the glove outer shell shall conform to MIL-DTL-32698

(see 6.6.1). Vapor barrier components are not permitted in the shell construction given the need for breathability and quicker dry time.

3.5.2 Leather. The leather used to construct the palm, fourchettes, and a portion of the thumb shall be a

2.25- to 2.75-ounce full grain goatskin conforming to the requirements in table I when tested as specified in 4.4.3.

The leather shall be chrome tanned, light finish, fungicide and durable water-repellent treated, and backed by a waterproofing layer. The suede side shall be used to construct a “nose wipe” on the back of the thumb. Unless otherwise specified (see 6.2), the shade of the leather shall be Coyote 498 (see 6.5.2), conforming to leather shade standard number 3898, and shall be drum dyed and struck through from grain to flesh.

4.5 Examinations and tests.

4.5.1 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 the standard atmospheric conditions environment, as specified in ASTM D1610. A stainless steel 500-milliliter, 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 gram) and then shall be placed inside the cover with the flesh side of the specimen next to the inside of the cover. The rubber gasket shall then be placed inside the cover and against the grain surface of the leather specimen. One-hundred milliliters of distilled or deionized water at 23 °C shall then be added to the container. The cover with the specimen and gasket shall then be secured to the container. The container shall then be inverted so the water is against the grain surface of the specimen. The inverted container shall be placed on a flat surface and allow it to remain in the inverted position for 30 minutes. At the end of 30 minutes, the container shall be placed upright, and the cover shall be removed and placed on a flat surface. The inside of the cover shall face the flat surface. The cover shall be tilted so the outer edge of the bottom is raised 1 to 1-1/2 inches from the flat surface and allowed to drain for 5 minutes. After 5 minutes, the specimen shall be removed from the cover, held by its edge, and shook briskly once to remove any free moisture from the surface of the specimen. The specimen shall be immediately reweighed to the nearest 0.01 gram; the percent water absorption shall be calculated as follows:

𝑃𝑒𝑟𝑐𝑒𝑛𝑡 𝑤𝑎𝑡𝑒𝑟 𝑎𝑏𝑠𝑜𝑟𝑝𝑡𝑖𝑜𝑛 = (𝑊2 − 𝑊1) × 100

𝑊1

Where:

W1 = Original weight of conditioned specimen

W2 = Weight of specimen after being subject to water

4.5.2 Thermal insulation test. Three separate samples of the test handwear shall be evaluated in accordance with ASTM F3426 and the average value shall be reported. Total thermal resistance (R) values can be converted to the more familiar clo unit, by multiplying the R value by 6.45, to allow ranking order of standard for procurement purposes. Test size shall be right hand, size large. A life-sized biophysical model of the human hand that measures localized and total thermal resistance shall be used. Insulation values for the total hand model and its eight individual regions are calculated by an internal program during 30 minutes of steady state data collection. The ambient temperature shall be maintained at 5±0.5 °C and the surface of the hand model is controlled at 35±0.5 °C.

The relative humidity shall be 50±5 percent and wind speed shall be maintained at 0.4±0.1 meter per second.

Samples evaluated after laundering shall be laundered in accordance with AATCC TM150. Total thermal resistance

(R) to heat exchange is calculated in the test conditions stated above and using:

𝑅 =

𝑆𝐴 × 𝑑𝑒𝑙𝑡𝑎 𝑇

𝑃

Where:

R = the thermal resistance, m2 °C/watt

SA = total surface area of seven regional segments, m2 delta T = temperature gradient between the hand model surface and ambient air temperature, °C

P = Total power input, watts

If required (see 6.2), gloves submitted will be tested by the Government. Testing at alternate facilities shall require side-by-side comparison due to chamber wind speed differences that cannot be controlled that will affect the total measured values.

4.5.3 Liner retention test and testing apparatus. Liner retention shall be evaluated with the use of locking forceps and a force-measuring gauge. A minimum of three finished items shall be tested. Each digit of the glove shall be tested as follows. The locking forceps shall be attached to the inner liner of the digit to be tested ensuring that an unattached liner or the outer shell is not grabbed. The hook of the force gauge shall be looped around the locking bridge of the forceps. The digit of the glove shall be gripped ensuring the inner liner is not impeded. The force gauge shall be pulled until the 6-pound (threshold requirement) and 8-pound (objective requirement) registers on the dial and then released. Each digit shall be inspected for indication of detachment of inner barrier liner.

Results shall be recorded and reported as pass or fail. Failure of any digit of any glove shall constitute failure.

Items shall be permitted to be cut open to verify detachment.

4.5.4 Spectral reflectance test. Spectral reflectance data shall be obtained from 600 to 860 nanometers at

20-nanometer intervals on a spectrophotometer relative to the polytetrafluoroethylene (PTFE) family of compounds, the preferred white standard. Other white reference materials may be used provided they are calibrated to absolute white or vitrolite tiles. The spectral band width shall be less than 20 nanometers at 860 nanometers. Reflectance measurements shall be made by either the monochromatic or polychromatic mode of operation. When the polychromatic mode of operation is used, the spectrophotometer shall operate with the specimen diffusely illuminated with the full emission of a continuous source that simulates either Commission of Illumination (CIE) source A or CIE source D65. Measurements shall be taken on a minimum of two different areas and the data averaged. The measured areas should be at least 6 inches away from the selvage. The specimen shall be measured as a single layer backed with three layers of the same fabric and shade. The specimen shall be viewed at an angle no greater than 10 degrees from normal, with the specular component included. Measurements shall be taken on a minimum of two different areas. Specimens shall be oriented in different directions during testing. When possible, the specimens tested shall not contain the same warp or filling yarns/Wales or courses when presented to the sample port. Camouflage materials should be measured with the appropriate aperture size to ensure that only one color is measured at a time. Always try to use the largest aperture possible. Photometric accuracy of the spectrophotometer shall be within 1 percent and wavelength accuracy within 2 nanometers. Any color having spectral reflectance values falling outside the limits at four or more of the wavelengths specified shall be considered a test failure.

4.5.5 Visual shade matching. Samples shall be viewed using AATCC EP9, option C (see 6.5), with sources simulating artificial daylight D65 illuminant (see 6.5.1) with a color temperature of 6500±200 Kelvin (K) illumination of 100±20 foot candles, and under incandescent A illuminant with a color temperature of 2856±200K.

5. PACKAGING

5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Point’s packaging activities within the Military Service 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.

6. NOTES

(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)

Invitations for bids should provide that the Government reserves the right to waive the requirement for samples for first article inspection to those bidders offering a product that has been previously acquired or tested by the

Government and that bidders offering such products, who wish to rely on such production or test, must furnish evidence with the bid that prior Government approval is presently appropriate for pending contract. Bidders should not submit alternate bids unless specifically requested to do so in the solicitation.

6.4 Standard sample. For standard samples, address the procuring activity issuing the invitation for bids or request for proposal.

6.5 Visual shade matching. In 2019, option A of AATCC EP9 was changed to option C. NOTE: In case of confusion, the viewing geometry should be such that the specimen plane and illumination source are parallel to each other and aligned so that the light flux is incident at the center of the specimen plane, which is set at a 35±5-degree angle relative to the horizontal. The observer will view the specimens at a 90-degree angle, relative to the plane of the specimens.

6.5.1 D75 illuminant. The use of D75 illuminant with a color temperature of 7500±200K and illumination of

100±20 foot candles in lieu of the specified D65 illuminant (see 4.5.4) is permitted.

6.5.2 Shade criticality. Some items may be deemed “non-shade-critical” by the contracting agency and alternative shade standards or information regarding shade may be specified in the contract or order (see 6.2). It is recommended that manufacturers refer to the contract or order to determine the criticality of the shade matching or alternate shade standards that are acceptable.
