The test refers to complete parts assembled as in a vehicle. Oven ageing with air circulation according to SS - ISO 188:2011 (3-10 times/hour). Ageing conditions: 80 ± 2° C for 1 000 h (components mounted vertically) or 2 000 h (components mounted horizontally) in a heating chamber, equivalent to 3 years in Arizona climate.Remark: If the chosen materials have sufficient temperature stability (as evaluated by VCC Materials Centre), ageing can be performed at 10 °C higher temperature using half the above stated test durations.
