Described is a testing system for performing specimen testing, such as residual seal force (RSF) testing and/or compression friction (CF) measurement testing. The testing system comprising a column supported by a base structure, a load cell supported by said column, a specimen plate configured to receive a plurality of specimens, a motor, and controller. The load cell is configured to move along the column toward and away from the base structure via a crosshead coupled to an actuator. The plurality of specimens comprising a first specimen and a second specimen. The controller is configured to control the motor to adjust a position of said specimen plate.

System, method, and apparatus for automating specimen testing

Described is a test head for a residual seal force (RSF) testing system. The test head includes a housing, an anvil, and a ball roller assembly. The housing defines a first cavity and the anvil is positioned at least partially within the first cavity. The ball roller assembly is configured to provide a point of contact between the housing and the anvil during a RSF test. The test head may further comprise a retaining ring configured to maintain the anvil at least partially within the first cavity.

Described is a compression apparatus for a testing system having a load cell. The disclosed compression apparatus ensures proper seating relative to the load cell to yield accurate compression friction (CF) measurements. The disclosed compression apparatus includes a compression rod and at least one mechanical fastener. The compression rod has a first portion at a distal end and a second portion that defines a threaded bore at a proximal end. The first portion is configured to contact a specimen and the second portion is configured to couple to the load cell. The mechanical fastener is configured to mate with the threaded bore.
