Abstract:
1. A method of testing a bond or fatigue strength of a seal lip on a metal substrate, comprising: providing a seal assembly having a metal substrate with an elastomeric seal lip bonded thereto; operably fixing the seal assembly to a support plate and orienting a seal lip axis along which the seal lip extends to extend along a predetermined axis; clamping the seal lip between pair of clamping fingers without causing damage to the seal lip; pulling the seal lip with a force imparted by the clamping fingers along the predetermined axis until the seal lip either separates from the metal substrate or tears; providing each of the clamping fingers with a recessed clamping surface adjacent to a free end of the clamping fingers and a raised surface extending outwardly and away from the recessed clamping surface; and clamping the seal lip between the recessed clamping surfaces and bringing the raised surfaces into abutment with one another.
