3. REQUIREMENTS

3.1 First article. The contractor will provide quantity one TATPE of all sizes except Small Short, Small Long, and Extra Extra Large Regular (total of 12) for first article testing and in accordance with 4.2.

3.2 Recycled, recovered, environmentally preferable, or biobased materials. Recycled, recovered, 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.

3.3 Design. The TATPE design consists of a coverall with attached hood, protective gloves and attached socks. The one (1) piece coverall shall be fabricated primarily with stretch laminate, static laminate, and non-protective static base fabrics. Type I shall use the sock pattern that has a T-shaped toe seam (see Figure 1). Type II shall use the sock pattern that has a Y-shaped toe seam (see Figure 2). For this effort, the Type II sock design shall be used. Stretch laminates shall be used in the hood, front torso, back torso, inner sleeves, crotch, and sock. The static laminate material shall be used in the outer sleeves, legs, at perimeter of mask seal, hood back panel, all pockets and flaps, knee, wrist and ankle tabs, zipper flaps and belt loops. Non-protective static material shall be used as the secondary layer in the zipper flaps, pocket flaps, wrist and ankle tabs. Abrasion resistant material shall be used on the elbows. The garment has tabs at the wrist, knee and ankle, as well as belt loops that accommodate typical military utility belts, to aid in the conformal design of the garment. The design also features protective closures at the rear shoulder area (don/doff), front waist (vertical waste relief) and front thighs (vertical passive heat exchange vent). Pockets are located on both upper sleeves, and on both outside thighs. The outer gloves are not attached and shall be stowed in the right cargo pocket. Pass-throughs are located in the hood at the rear neck (for the exhalation exhaust valve), and the right hip (for the microclimate cooling liquid pass-through). The pass-throughs are fabricated with Low Density Polyethylene (LDPE) reinforcement gasket to provide a smooth surface onto which the exhaust valve and cooling liquid pass-through are fastened and sealed. External pouches on each knee contain removable elastomer foam knee pad inserts and an external semi-rigid abrasion protective knee pad that is sewn to the exterior pouch.

b. From inside the suit, align the LPT Inner Half threaded studs and alignment pins with the holes in the LPT Patch. Ensure that the four (4) threaded studs and the two (2) alignment pins fully protrude through the small holes. Use fingertips to lightly press the external LDPE ring flat and ensure that it is seated against the base of the threaded studs and alignment pins. The LPT internal tubing should be routed in an upward direction. The LPT external tubing should be routed in an upward and rearward direction.

c. Align the protruding threaded studs and alignment pins with the holes in the LPT Outer Half. The LPT external tubing should be routed in an upward and rearward direction.

d. Locate the four (4) Barrel Nut Fasteners. Place one Fastener onto each threaded stud. Using the Torque Driver and 7/64-inch hex bit, tighten each Fastener to 12 in-lbs, using a cross-pattern.

e. When microclimate cooling is not used, the LPT may be stowed using the elastic keeper located above the leg pocket on the protective garment.

f. Alternatively, the LPT may be removed from the protective garment and replaced with the LPT-Plug. Replacing the LPT is accomplished by removing the Barrel Nut Fasteners, separating the Outer and Inner LPT Halves from each other and the protective garment, and installing the Outer and Inner LPT-Plug Halves onto the protective garment by generally following steps a through d above.

Material vendor will also provide performance data for the Flame Resistance properties of the Static material.

4.3 Conformance inspection. Lot Acceptance Testing (LAT) shall be conducted on lots of completed overgarments submitted for acceptance. Sampling for production lot testing is indicated below. Each lot of overgarments shall contain items manufactured from the same lot of material as indicated by the Production Lot Surveillance Marking No. Sampled items shall be examined for defects as listed in Table X and subjected to the tests as specified in the LAT column of Table XI. Failure of any LAT test shall fail the entire lot. Manufacturer must perform a root cause and corrective action investigation and submit documentation of that investigation prior to submitting new samples for re-testing. Failure of any LAT retest shall reject the lot and no further submission will be accepted for that production lot. Conformance inspection shall include the examination of 4.4 and the tests of 4.5 through 4.6 as applicable. Sampling for LAT inspection shall be performed in accordance with the following table, ASQ/ANSI Z1.4, and with acceptance quality limits as specified in the contract or purchase order, except where otherwise indicated in 6.2.

4.3.1 Inspection conditions. Unless otherwise specified in this specification or applicable procurements documents (see 6.2), all inspections shall be performed in accordance with this specification and all the requirements of referenced documents.

4.4 Visual examination. The finished TATPE overgarments shall be examined for the defects listed in Table X.

4.4.1 Individual critical defect examination. The manufacturer shall conduct 100% inspection of the overgarments for critical defects in accordance with Table X. Presence of any critical defect or more than 2 major defects shall be cause for rejection of the lot.

Defect classifications are defined as follows:

Critical: Will cause lethal exposure; significant degradation to personnel or mission; significant manufacturing defect as defined by the quality standards and will cause rejection of garment or lot.

Major: Potential for lethal exposure; degradation to personnel or mission; manufacturing defect as defined by the quality standards and may cause rejection of garment or lot.

Minor: Low probability of exposure; may impact personnel or mission; defect that exhibits manufacturing flaw as defined by quality standards, but will not result in rejection.
