Thermal
ageing test
(DO
9.21-4360)
This standard describes a bending test on
thermally aged specimens. The test conduits
are stored in a controlled-climate
oven at the specified test temperature. After
removal from the oven, they are cooled
to room temperature. Loading is achieved
by winding the specimen around a test
mandrel with a defined diameter. The various
products are classified based on the
mandrel diameter which can be achieved.
