4.3.2 Arrangement. The first article craft shall be examined to verify compliance to 3.2.1.1 through 3.2.1.3, 3.2.2 through 3.2.4.3, 3.2.7 through 3.2.9.3, 3.2.10.1, and 3.2.11 through 3.2.14. The bid sample shall be tested to verify compliance to 3.2.1.4, 3.2.4.4, 3.2.5, 3.2.6, 3.2.9.4. The craft shall be hoisted with the operational payload (1,550 kilograms) to verify compliance to the requirements of 3.2.6 and 3.6.9. During Calm-and Rough-water performance trials, the bid sample shall be observed to verify compliance to the requirements of 3.2.9.4 through 3.2.11.

4.3.3 Inflation System. The first article craft shall be tested to verify compliance to the requirements listed in 3.3.

4.3.4 Material Requirements. The manufacturer shall provide independent laboratory reports that confirm compliance to 3.4. Those reports shall be examined to verify compliance to the requirements of 3.4.

4.3.5 Performance. The first article craft shall undergo testing to verify compliance to the performance requirements of 3.5.1, 3.5.2, and 3.5.4.

Tests performed to validate compliance to section 3.5.13, 3.5.2.4, and

3.5.2.5 shall be conducted for a distance of 0.4 kilometers. If an inflatable chamber fails the air retention requirements of 3.5.4 it will be retested with the adjacent chambers deflated. If that chamber still does not meet the requirements of 3.5.4 it will be considered non-compliant to that requirement. The bidder shall provide test documentation that verifies compliance to the requirements of 3.5.3.

4.3.6 Accessories. The first article craft shall be examined to ensure compliance to the requirements of 3.6. The bid sample shall be tested to verify compliance to performance requirements of 3.6.7, 3.6.9, and 3.6.10.5 through 3.6.10.8

4.4 Conformance Inspections. Conformance inspections may be conducted periodically to verify that production lot craft are compliant with many of the requirements of 3.0. The requirements for Conformance Inspections are as follows:

4.4.1 Physical Dimensions and Characteristics. A production lot craft shall be examined to verify compliance to 3.1.1 through 3.1.6

4.4.2 Arrangement. A production lot craft shall be examined to verify presence of the items described in 3.2.1 through 3.2.14.

4.4.3 Inflation System. A production lot craft shall be examined to verify presence of components described in 3.3.3 through 3.3.5.

4.4.4 Performance. A production lot craft shall be tested to verify compliance to the leakage rate requirement of 3.5.4

4.4.5 Accessories. A production lot craft shall be examined to verify the presence of the accessories identified in 3.6.1 through 3.6.10.
