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.

The strength measuring apparatus includes: a strength measuring instrument measuring the strength of the mold on the basis of a reaction force received from the mold; a moving unit moving the strength measuring instrument; a distance sensor measuring a distance to an object on the conveyance line; and a control unit controlling the moving unit, wherein the control unit determines a measurement position of the strength measuring instrument in a horizontal direction perpendicular to a conveyance direction of the conveyance line on the basis of the distance detected by the distance sensor and controls the moving unit to move the strength measuring instrument to a position above the measurement position.

A method and a system for analyzing a physical characteristic of a film sample are described herein. The system includes a material holder system configured to hold the film sample; and a tear analysis device configured to tear the film sample and measure a characteristic of the tear. The movable system is configured to move the film sample in the material holder system to the tear analysis device.

A mold coating agent test device includes a frame positioning portion and a connection positioning portion. The frame positioning portion positions a frame portion of a metal mold such that the frame portion of the metal mold is positioned at a predetermined position when the metal mold is placed on a metal block. The connection positioning portion positions a connecting portion such that the connecting portion that is a portion provided in the frame portion and to which a drive unit that applies a force is connected is positioned at a predetermined position when the metal mold is placed on the metal block.

A material testing machine, including a machine body, a first fixing element, a second fixing element and a detection assembly; the first and the second fixing elements are mounted to the machine body, the first fixing element is configured to mount a first testing element, and the second fixing element is configured to mount a second testing element; in a first state, the first and the second testing elements are in sliding contact; in a second state, the first fixing element drives the first testing element to collide with the second testing element; the detection assembly is configured to detect a target parameter, and in the first state, the target parameter includes a friction force and/or, a friction sound between the first and the second testing elements; and in the second state, the target parameter includes a collision force received by the first or the second testing element.

A support jig for use with a testing machine applying loads, the support jig includes a frame and a pair of spaced apart supports joined to the frame to provide an alignment axis. Each support is configured to releasably hold a test specimen holder on the alignment axis in a fixed spatial relationship with ends of the test specimen holders mountable to the test machine facing in opposite directions. A test specimen support is located between the holders holds the test specimen on the alignment axis so that the holders can be attached to the test specimen. The support jig allows the holders to be easily and correctly attached to the test specimen so as to maintain alignment of the holders and the test specimen on the alignment axis. The support jig also maintains the fixed spatial relationship of the holders and test specimen while the holders are mounted to the test machine.

A system and method for performing a tear test are described herein. The system may include a fixed clamping station configured to hold a first portion of a film specimen and a movable clamp coupled to an actuator, the movable clamp may be configured to hold a second portion of the film specimen. The movable clamp may be configured to move in a direction away from the fixed clamping station to tear the film specimen. The system may include a slitter blade configured to cut the film specimen at a location between the fixed clamping station and the movable clamp. The system may include a load cell coupled to one of the fixed clamping station and the movable clamp. The load cell may be configured to measure a force associated with tearing of the film specimen. The actuator may be configured to manipulate the movable clamp along a trajectory.

Hardness testers having a pivoting body and capable of providing power to accessories on the pivoting body are disclosed. An example hardness testing device includes: a rotating carriage configured to: hold at least one of an indenter or an objective and at least one accessory; and rotate to selectively place the at least one indenter or objective or the at least one accessory in an operative position to operate the at least one indenter or objective or the at least one accessory; a carriage mount configured to support the rotating carriage; and an electrical contact block mounted stationary with respect to the carriage mount, the electrical contact block comprising a plurality of electrical contacts configured to make electrical contact with a counterpart electrical contact block of the at least one accessory coupled to the rotating carriage when the at least one accessory is positioned in the operative position.

A fixing jig is provided, including a supporting base, a fixing plate, and a fixing component. The supporting base includes a first upper surface. The fixing plate is disposed on the supporting base. A side of the fixing plate is pivotally connected to the supporting base and includes a second upper surface, a bottom surface, and via a hole. The fixing component presses the fixing plate on the second upper surface. The fixing jig can fix an object pending testing and allows one flexible electric circuit board of the object pending testing to be exposed outside of the fixing jig, so that when performing a pull force test, this can allow an angle between two flexible electric circuit boards to be 90 degrees, thereby improving accuracy of an experimental result.
