Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Example specimen measurement devices include a clamp; a single actuator configured to control the clamp to position a specimen with a clamping force; a measurement probe configured to contact the clamped specimen with a probing force; and a single position sensor configured to measure a dimension of the clamped specimen based on detecting a position of the measurement probe.

Abstract: Systems and methods are provided for handsets for testing devices with fluid ingress mitigation.

Abstract: The present disclosure provides an electro-mechanical fuse-type configuration built into the probe that contacts the specimen during materials testing. The design includes an internal pre-loaded compression spring and an electrical contact switch. The coil spring preloaded to the desired safety load results in the probe assembly directly passing the load from the probe tip to the load cell for loads under the point where the spring additionally compresses. Upon deflection of the spring in excess of safety preload, the spring internally compresses within the probe coupling rather than the probe tip continuing to displace into the specimen, thereby switching the state of the electrical contact switch and stopping operation of the materials testing device. In a further configuration, excessive travel of the load cell coupling is detected, and, in response, operation of the materials testing device is stopped.
