A rotary rheometer has two measurement parts which delimit a measurement gap and can be moved relative to one another in a predetermined movement direction by an adjustment device. At least one switching unit is provided, which responds to changes in a force flow in a force circuit of the rotary rheometer delimited by the measurement parts and has switching contacts for the activation of an adjustment device, which stops the adjustment device when a predetermined limit force value is exceeded for the force flow in the positive or negative direction, optionally without relative movement of the measurement parts, or with the measurement parts remaining in the same position.

Safety systems and material testing systems including safety systems are disclosed. An example material testing system includes: at least one actuator configured to control one or more operator-accessible components of the material testing system; an actuator disabling circuit configured to disable the at least one actuator; and one or more processors configured to: control the at least one actuator based on a material testing process; monitor a plurality of inputs associated with operation of the material testing system; determine, based on the plurality of inputs and the material testing process, a state of the material testing system from a plurality of predetermined states, the predetermined states comprising one or more unrestricted states and one or more restricted states; and control the actuator disabling circuit based on the determined state.

An apparatus for testing paving samples includes a base that includes a paving sample tray about the cabinet and configured for translation relative to the cabinet. A roller is configured for imparting compressive forces to a sample carried by the sample tray. An arm is configured for moving the roller from a stowed position to an in-use position where the roller contacts the sample. A cylinder assembly having a piston therein supplies pressure forces to the arm to move the arm from the stowed position to the in-use position, wherein a depth of travel of the arm is limited by the sample. As the sample is compressed, the depth of travel increases. A measurement device is in communication with the cylinder for determining an amount of travel of the arm to thus determine an amount of compression of the sample.

A hardness tester includes an indenter, an arm and a driver which loads a test force onto the indenter and press the indenter against a sample, a spring displacement amount sensor detecting a value for the test force loaded onto the indenter, and a controller. In a state where a predetermined test force (total test force) is loaded onto the indenter by the driver, when the value of the test force detected by the spring displacement amount sensor exceeds a predefined allowable margin relative to the predetermined test force, the controller executes predetermined processes, including an interrupt process interrupting the test currently being executed and a notification process notifying a user that the value of the test force exceeded the allowable margin during execution of the test.

Techniques are described for configuring a materials test system to perform materials tests on sample material(s). Such a materials test system may include a test controller and materials test device(s), which are connected to the test controller. In an embodiment, the materials test system receives input selecting a test controller type for the test controller of the materials test system and input for configuring a materials test device. Without the materials test system being connected with the test controller and the materials test device, generating configuration data based on the inputs. The generated configuration data may be loaded into the test controller, thereby configuring the materials test system.

A rotary shock testing machine including: a base; a shaft rotatable relative to the base; a test disc for holding one or more specimens to be tested, the test disc being rotatable with the shaft; an actuator for applying a rotation to the shaft and test disc; and a brake for applying a braking force to the test disc to subject the one or more specimens to a rotary shock.

A rotary shock-testing machine including: a base; a first shaft rotatable relative to the base, the first shaft being driven to rotate; a first wheel rotatable with the first shaft; a second shaft rotatable relative to the base; a second wheel rotatable with a first portion of the second shaft; and a test disc for holding one or more specimens to be tested, the test disc being rotatable with a second portion of the second shaft; wherein the first and second wheels are aligned with each other such that the second wheel is driven by the first wheel when a material is introduced into a gap between a surface of the first wheel and a corresponding surface of the second wheel.

A system for pipeline testing uses an electronics control module to monitor remote sensor data and compare the remote sensor data to control parameter input data that includes data indicating acceptable testing parameter ranges. In response to the comparison of the real time sensor data and the control parameter input data, the electronics control module generates various control signals used to control an automated fluid control system to regulate the pressure in the pipeline being tested and, if necessary, instigate an emergency shutdown of the test and to release all pressure from the section of pipe being tested. All test data is recorded, stored, and made available as needed/desired.

Described is a method of controlling a material testing system that includes controlling an actuator to transfer a first force acting in a first direction to a test material. The method further includes receiving, via one or more sensors, continuous data indicating one or more physical quantities associated with the test material. Based upon the continuous data, it may be determined that a change in one or more physical quantities has occurred. Based upon a change in one or more physical quantities it may be determined that an end point of a material test has been reached. The method further includes controlling an actuator to stop transfer of the first force and further to controlling the actuate to transfer a second force which acts to counteract the effects of the first force and prevent unwanted motion of one or more portions of the material testing system.
