Unless otherwise noted herein or in the contract, in the event of a conflict between the text of this document and the references cited herein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 3. REQUIREMENTS

    3.1 First article. When specified (see 6.2), a sample shall be subjected to first article inspection in accordance with 4.2. 3.2 Standard sample. The finished webbing shall match the standard sample for shade and appearance, and shall, unless otherwise indicated, be equal to or better than the standard sample with respect to all characteristics for which the standard sample is referenced (see 6.4).

    3.3 Recycled, recovered, or environmentally preferable, or biobased materials. Recycled, recovered, or environmentally preferable or biobased materials should be used to the maximum extent possible, provided that the material meets or exceeds the operational and maintenance requirements, and promotes economically advantageous life cycle costs. 3.4 Material. 3.4.1 Yarn. The nylon yarn for the warp and filling shall be singles, bright, high tenacity, continuous filament nylon, which has not been subjected to any type of bleaching process. For Class 1 webbing, only nylon 6,6 shall be used. For Class 2 webbing, nylon 6 or nylon 6,6 shall be used. 3.4.2 Yarn size. The yarn size shall be 840 denier (warp and filling) for shuttle loom construction and a combination of 840 denier warp and 420 denier filling for shuttleless construction. 3.5 Color. The color/print of the webbing shall be as specified by the applicable end item or in the contract/purchase order. 3.5.1 Visual shade matching. The color and appearance of the webbing shall match the standard sample when tested as specified in 4.7.2. 3.5.2 Colorfastness. The finished webbing shall conform to the colorfastness requirements listed below in Table I when tested as specified in Table V.

    3.7 Woven or printed. The webbing shall be jacquard woven or printed in the Operational Camouflage Pattern (OCP) four (4) colors (when applicable). When printed, the webbing shall be dyed to a ground shade to match Tan 499 and then it shall be overprinted with the remaining three (3) camouflage colors (Olive 527, Brown 529 and Dark Green 528) (see 6.2).

    3.8 Pattern execution. The pattern on the printed or jacquard woven webbing (when applicable) shall reproduce the standard sample in respect to design and colors of the respective area/colors. When the standard sample is not referenced for pattern execution, a pattern drawing shall be provided and the pattern shall match that of Drawing 2-1-2592 for respective colors in Operational Camouflage Pattern (OCP) (see 6.2).

    3.9 Spectral reflectance (solid colors). The reflectance values for the webbing in solid colors for all classes shall conform to the requirements listed below in Table II when tested as specified in 4.7.3.
