The objective of the work program for process improvement and testing of production lots of metallized polycarbonate film and metallized polysulfone film hermetically sealed capacitors was to a failure rate under static test conditions with a goal of .002 per 1000 hours for each dielectric, based on testing 11,500 of each for 10,000 hours. The original contract goal had been . 001 per 1000 hours based on testing 23,000 metallized polycarbonate film capacitors. However, the contract modification deleting 11,500 of metallized polycarbonate film capacitors and substituting 11,500 of metallized polysulfone film capacitors changed the maximum attainable FR for each dielectric to .002 per 1000 hours.
