According to PMA DO 9.21-4360 test procedures


This standard describes a procedure designed to evaluate the thermal stability of a conduit and its resistance to thermal ageing.

The conduit is exposed to a temperature significantly above the maximum recommended continuous operating temperature for 168 hours, 160°C (PA6) or 150°C (PA12).

The Flexibility at Low Temperature procedure DO 9.21-4380 is performed both before and after the thermal ageing procedure. The results are compared to detect any change in material characteristics.
