How can I determine if I bought the correct barrier material?

MIL-PRF-81705 requires material to be identified per paragraph 3.6 to ensure material was produced by a qualified source. Specific markings are outlined. These markings are required for material to be considered compliant and for inspectors and customers to properly identify material as a qualified barrier material. These markings must be present, no exceptions or deviations permitted. Military barrier materials are identified by their markings. For determining if you actually received MIL-PRF-81705, check for the following information. Two groups of markings are used to identify the material.

  • The first group include:
    • Specification number
    • Type
    • Manufacturer's name
    • Manufacturer's designation
    • Month and year of manufacture
    • Lot number
  • The second group identifies the protective qualities:
    • Type I - EMI/STATIC SHIELD
    • Type III - STATIC SHIELD

The two groups appear sequentially, running the length of the barrier, with 1 inch space between the groups. A complete group of markings will appear every 6 inches of the roll width or flat cut sheets. When the material is used to make bags, both groups of markings must be visible within the DOD supply chain.
