Abstract: A method for testing a performance of a plurality of sealing members includes providing a testing fixture including at least two blocks in a contacting relationship with a plurality of fixtures. Each of the plurality of fixtures defines a groove portion for receiving a sealing member. The method further includes connecting each of the plurality of fixtures with a fluid manifold. The method also includes controlling a temperature of each of the at least two blocks and the groove portion using a thermal device. Each of the at least two blocks and the groove portions are at temperatures different from each other. The method also includes passing a fluid through each of the plurality of fixtures so as to flow through a channel provided adjacent to and surrounding the groove portion. The method further includes monitoring a response of the sealing members to determine at least one performance parameter.
