Bob said: >MTBF simply means "Mean Time Between Failure", Mean is the arithmetic average. On the average, the unit in question will fail at that point, some less, some more and the variation of when the item will fail is dependant upon the sigma of the distribution< No disagreement, Bob. You need a lot more data than one point on a curve to make any estimate of when an equipment or component is going to fail, and you have to establish exactly what your failure criteria is, as well. 73 Peter G3RZP _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
