39、 EIA-364-1000A Page B-2 B.9 Temperature life B.9.1 To evaluate the susceptibility of the connector or socket to the damaging effects caused by stress relaxation of the contacts, while allowing for other thermally activated material transformations, such as base metal diffusion to the contact interfa

40、ce and surface treatment degradation at the contact interface, to occur NOTE It is extremely difficult to define a single temperature life test that is efficient and accounts for every thermally activated material transformation. In fact, little data is available pertaining to some of these processe

41、s (i.e., the behavior of surface treatments over a significant range of exposure durations and temperatures). That being the case, the test durations and temperatures of table 8 were selected after consideration of the stress relaxation behavior of brass and phosphor bronze. The reasoning for this s

42、election is as follows. B.9.1.1 There is substantial data on the amount of stress relaxation in these copper alloys over a significant range of exposure durations and temperatures. B.9.1.2 The amount of stress relaxation in beryllium-copper at equivalent exposure durations and temperatures is neglig

43、ible. B.9.2 Each set of test conditions (duration and temperature) yields about the same amount of stress relaxation as that found in brass or phosphor bronze after the corresponding field exposure. B.10 Temperature life (preconditioning) B.10.1 To accelerate thermally activated material transformat

44、ions, thereby assuring that the contacts subjected to subsequent testing are representative of an aged condition NOTE Similar to the temperature life test, (see B.9), it is very difficult to define a single temperature life (preconditioning) test that efficiently accounts for every thermally activat

45、ed material transformation. Once again, and for the same reasons, the test durations and temperatures of table 9 were selected after consideration of the stress relaxation behavior of brass and phosphor bronze. B.10.2 Each set of test conditions (duration and temperature) results in 85% of the stres

46、s relaxation found in brass or phosphor bronze after the corresponding field exposure.
