Beschreibung
Zusammenfassung:	The proposed method of accelerated aging tests of articles consists in determining the temperatures in tests and the lengths of the test stages, at which the accelerated tests are equivalent to the normal tests of the article, heating the article to a specified maximal temperature by stepwise changing the temperature with an increment of 5 ... 15 ?C. holding the article at intermediate temperatures for (0,25 à 0,35)?, where ? is the design service life of the article, holding the article at a maximal temperature for (0,65 à 0,75)?, than cooling the article to a normal temperature by stepwise changing the temperature with an decrement of 5 ... 15 ?C.
