APPENDIX A – SURVIVABILITY, RELIABILITY & VERIFICATION

1.0 First Article Testing (FAT)

First Article Tests will be separately priced items according to the terms and requirements set forth in each Task Order (TO). No deviations will be accepted without a modification to the TO. FATs are performed once for each Operational Transit Cases (OTC*) that contains a V1+ or V2, V1+, V2 and V3 configuration item to verify that the CHS-6 items satisfy all survivability requirements and meet the product specifications. This first article will serve as the manufacturing standard. Additional items procured, upholding the same configuration management requirements as the first item tested, will not need to reaccomplish FAT. IAW FAR 15.404-1(g), the price for the FAT and the pricing for the production quantities shall not be materially unbalanced.

All OTCs* that contain a V1+ or V2, V1+, V2 or V3 items added to the CHS contract undergo FAT unless specified otherwise in the accepted TO. FAT consists of hardware-specific survivability and reliability verification (visual, mechanical and electrical). At least one unit of the particular item undergoes FAT. V1 items are not required to have a FAT performed. FAT may be performed at the contractor’s facility or subcontracted and shall be witnessed and subsequently certified by the Government.

The delivery schedule for the production quantity will be included in the terms and requirements of the individual TO.

Note: OTCs shall undergo testing when required by the Government as specified in the TO. For simplification purposes the abbreviation OTC* is used in this document to signify OTCs that require testing rather than those that do not require testing.

Note: V1+* – The abbreviation V1+* is used when the Government requires more stringent Humidity testing as defined in Table A-1.
