A loading frame for fiber reinforced polymer (FRP)-concrete bond tests includes a standing guide tower, a base section, and a loading beam. The standing guide tower is perpendicularly mounted to the base section. A testing load is applied to the loading beam when performing a series of FRP-concrete bond tests. A sliding end of the loading beam is positioned into a channel within the standing guide tower allowing the loading beam to be positioned at a preferred height. The engagement between the loading beam and the standing guide tower reduces secondary forces. The loading frame is mobile and may also be used with existing testing devices and systems used to perform the series of FRP-concrete bond tests.

The invention relates to a force measuring arrangement (3) in particular for applying a test parameter to a specimen and/or for measuring a resistance force applied by the specimen, having at least one force absorption element (25), a first fastening device and a force transmission element (27), wherein the force absorption element (25) can be fastened to a force measuring device in a movable manner by means of the first fastening device, wherein the force absorption element (25) is designed to measure a relative force acting between two force absorption regions, namely a first force absorption region and a second force absorption region (51), wherein the first fastening device is able to be connected to the force absorption element (25) in a force-transmitting manner via the first force absorption region, wherein the second force absorption region (51) is able to be connected to the force transmission element (27) in a force-transmitting manner by means of a second fastening device, wherein the force transmission element (27) is designed to apply a test parameter to a specimen. The force measuring arrangement is notable in that the second fastening device has a magnet (37) that is designed to retain the force transmission element (27) at least in a state connected to the second force absorption region (51) in a force-transmitting manner.

A system for testing adhesive is disclosed, comprising a pull testing machine and a rigid spine. The rigid spine has a face extending along a longitudinal axis between a first and second projection, and one of the projections is moveable relative to the other. The face is configured to support a substrate, with a flexible media adhered to the substrate. The rigid spine also has a coupler configured to connect the spine to the pull testing machine.

An electromagnetic multiaxial fatigue testing machine includes a test piece fixing platform and an electromagnet loading mechanism arranged on a frame, wherein the electromagnet loading mechanism includes a first loading device for bend loading, and a second loading device for axial and torsional loading. The first loading device includes a first permanent magnet and a first electromagnet with a direction of a magnetic force generated therebetween is orthogonal to an axial direction of a test piece; the second loading device includes a second permanent magnet and a second electromagnet mounted on a swinging pair with a direction of a magnetic force generated therebetween is parallel to the axial direction of the test piece.

A lift table includes a first adjuster having a base with a bore and a collet that is threaded into the bore of the base, the first adjuster being configured to selectively secure the lift table to the load frame, and a plate that sits atop the collet, the plate being configured to hold a fixture that is attached to the load frame. Rotation of the collet in a first direction relative to the base raises the plate and rotation of the collet in a second direction relative to the base lowers the plate.
