Known Failure Rates for specific environments and temperatures may be placed into GPRD library - Field Failure Rate Tables and then GPRD calculation method may be used to calculate FR for the selected component using existing FR data.

 

For example, manufacturer provided FR data for some part with PN=GA89723 for GB environment and temperatures 20 and 80 degrees. These data may be entered into the GPRD library under specific Part Number:

 

Then you have this part in your Bill Of Materials, in device used in GF conditions under 50 degrees temperature. Using GPRD library and GPRD reliability calculation method, you may get the FR calculated for specific project environment condition and temperature.

 

See GPRD paragraph for information about using GPRD Library and Using GPRD Library in Reliability Prediction paragraph for using GPRD reliability calculation method.
