Zeitraffung, Beschleunigung und Kombination von Umweltprüfungen

An improtant aim of the environmental qualification of a technical product is the assessment of its long-term behaviour. To get a shelf-life-prognosis there are different strategies depending on how the ageing behaviour is governed by episodical or continuous environmental loads. On the base of cause effect-relations there are eventually ways to compensate the duration by the intensity of an environmental load. Time dilation or accelerated ageing are only possible if the appropriate cause-effect-relation is known. Time laws as Fick's law request an ingenious modelling of dynamic load changes. Another smart time dilation depends on improved measurement methods concerning the material behaviour. Principles of Test Tailoring are also valid for the question of the rank order of tests depending on the life-cycle of a technical product or on the expected failures
