The sample shall be manufactured from the same material; process and manufacturing cycle as for the production run, including any sub-contracted processing based on production ready work instructions. Whenever practical, variable data is to be recorded and the inspection device documented. A sample of 5 pieces will be utilized for FAI. When a Key characteristic is specified by the engineering document, then an additional 5 pieces are measured. In the case of a tooling (i.e. crimpers, dies, etc.) 1 piece shall be sufficient for the FAI. First article inspection approval is accomplished using an approved form, such as Winchester Interconnect FAI,QAF034 for cables and RFMQAF034 for division connectors or approved equivalent. FAI data will be reported using the same units as the engineering document. Note: If the sample does not pass its material\functional test, the product supplied with the samples shall be considered unacceptable and shall require improvement and corrective action or may result in failure to be awarded the purchase order. Winchester Interconnects waiver of first article samples does not relieve Seller from meeting drawing and/or specification requirements.
