4.4.6.1 Sampling and acceptance criteria for verification of physical requirements. Sampling shall be in accordance with table V. The sample unit shall be 5 continuous yards, full-width, of the finished cloth per roll of cloth in the sample. The lot shall be unacceptable if one or more sample units fail to meet any test requirements specified in this document.

4.4.7 Visual shade matching. The color and appearance of the 70D nylon ripstop shall match the standard sample under sources simulating artificial daylight D65 illuminant (see 6.4.1) with a color temperature of

6500±200 Kelvin and illumination of 100±20 foot candles. Under these conditions, the color and appearance of the final fabric shall also be a good match to the standard sample under incandescent A illuminant with a color temperature of 2856±200 Kelvin.

DRAFT DATED 18 DECEMBER 2024

4.4.8 Toxicity test. When specified (see 6.2), an acute dermal irritation study and a skin sensitization study shall be conducted. When the results of these studies indicate the fabric may be a sensitizer or irritant, testing shall be conducted in accordance with Title 40 CFR (see 6.6). If the toxicity requirement (see 3.12) can be demonstrated with historical use data on the finishing treatments used, toxicity testing may not be required (see 6.2).

4.4.9 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 International Commission on

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. Specimens shall be oriented in different directions during testing. When possible, the specimens tested shall not contain the same warp or filling yarns or 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. The largest aperture possible should be used. Photometric accuracy of the spectrophotometer shall be within one percent, and wavelength accuracy shall be 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.

4.4.10 Drying time. The drying time test shall be run in standard textile conditions (65±5 percent relative humidity and 70±4 degrees Fahrenheit) on three specimens. The two-inch by two-inch (2" x 2") fabric samples and blotting paper shall be conditioned at standard textile conditions for a minimum of 4 hours. The weight of the conditioned specimen shall be measured using a laboratory balance, accurate to 0.01 gram. A wire mesh kitchen/bathroom sink strainer may be used by placing it on the weight pan of the lab balance in an inverted manner and taring its weight before the measurement of any specimen weight. After weighing the samples, 100 milliliters of distilled water shall be placed into a 250-milliliter glass beaker. The specimen shall be completely submerged (to ensure complete wetting) in the beaker of water for 30 minutes. The specimen shall then be removed and placed between two pieces of unused blotting paper. The blotting paper-enclosed specimen shall be passed through a motor-driven wringer (see 6.5.2) with a dead weight load of 27.2±0.5 kilograms (60±1 pounds) and speed of 1 inch per second. The specimen shall immediately be placed on the balance with the top door of the balance open and the side doors closed. The wet weight shall be recorded to the nearest 0.01 gram. The weight shall be manually monitored at set intervals until dry; alternatively, an automated balance with the capability to weigh the specimen until dry may be used. The degree of dryness shall be determined by the user. The time to dry (t) shall be recorded.

This process should be repeated for the remaining specimens.

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.
