MIL-DTL-26521L
6.3 First article. The contracting officer should include specific instructions in acquisition documents
regarding arrangements for examinations, approval of first article test results, and disposition of first
article samples. 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 which 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 the pending contract.
6.3.1 First article test report. First article tests reports should be prepared in accordance with
MIL-HDBK-831.
6.3.2 Defense Logistics Agency (DLA) waiver of first article test. A waiver of a first article testing will
only be considered by DLA when the contractor has delivered the same item within the last 3 years, has
no unfavorable quality history, has not changed processes, or changed any subcontractors. DLA will not
accept first article testing results outside the stated requirements.
6.4 Shelf life. This specification covers items where the assignment of a Federal shelf-life code is a
consideration. Specific shelf-life requirements should be specified in the contract or purchase order, and
should include, as a minimum shelf-life code, shelf-life package markings in accordance with MIL-STD-
129 or FED-STD-123, preparation of a material quality storage standard for type II (extendible) shelf-life
items, and a minimum of 85 percent shelf-life remaining at time of receipt by the Government. These and
other requirements, if necessary, are in DoD 414.27-M, Shelf-life Management Manual. The shelf-life
codes are in the Federal Logistics Information System Total item Record. Additive information for shelf-
life management may be obtained from DoD 4120.27-M, or the designated shelf-life Points of Contact
(POC). The POC should be contacted in the following order: (1) the Inventory Control Points (ICPs) that
manage the item and (2) the DoD Service and Agency administrators for the DoD Shelf-Life Program.
Appropriate POCs for the DoD Shelf-Life Program can be contacted through the DoD Shelf Life
Management website: https://www.shelflife.hq.dla.mil/.
6.5 Environmentally preferable material. Environmentally preferable materials should be used to the
maximum extent possible to meet the requirements of this specification. As of the dating of this
document, the U.S. Environmental Protection Agency (EPA) is focusing efforts on reducing 31 priority
chemicals. The list of chemicals and additional information is available on their website at
https://www.epa.gov/osw/hazard/wastemin/priority.htm. Included in the list of 31 priority chemicals are
cadmium, lead, and mercury. Use of these materials should be minimized or eliminated unless needed to
meet the requirements specified herein (see section 3).
