A test system includes subsystems for application to a test sample of a range of conditions that might be encountered in an actual application. Conditions may include the presence of particular fluid environments, temperatures, pressures, and mechanical loads including tensile and bending loads. The system is particularly suited for elongated samples such as tubular products used in oil and gas applications, though a range of samples may be tested.

A method of inspecting a secondary bond of a laminated part includes positioning the laminated part within a sealed chamber. The method also includes reducing a pressure within the sealed chamber to below a pressure outside the sealed chamber when the laminated part is positioned within the sealed chamber. The method further includes, when the pressure within the sealed chamber is reduced to below the pressure outside the sealed chamber, measuring a gradient of change of a surface profile of the laminated part. The method additionally includes determining a condition of the secondary bond based on the gradient of change of the surface profile of the laminated part.

A system for ultra-high temperature in-situ fretting fatigue experiment, includes a heat preservation cover defining a, a heating device arranged in the mounting space, a first test sample, a second test sample, and a clamping device arranged in the mounting space. The first test sample and the second test sample are arranged at an upper end of the heating device along a horizontal direction. A mortise is formed at an end of the first test sample facing towards the second test sample. A tenon mating with the mortise is formed at an end of the second test sample facing towards the first test sample. The clamping device is configured to be clamped at two ends of the mated first test sample and second test sample and to apply a periodically reciprocating loading along a length direction of the first test sample and the second test sample.

Disclosed is a testing apparatus and a testing method using the same, the apparatus having soil in a vacuum chamber includes: a buffer chamber having an entrance/exit opening through which an object to be inspected is inserted, and a first door for opening and closing the entrance/exit opening; a testing chamber divided at one side of the buffer chamber so as to be separated therefrom, and having a connection passage communicating with the buffer chamber; a shutter unit for opening and closing the connection passage; a soil storage part disposed inside the testing chamber, and accommodating soil for testing the object to be inspected; and a vacuum generation means for suctioning air inside the buffer chamber and the testing chamber so as to create a vacuum state.

The invention pertains to performing bonding strength testing between a test material and a container. A sample preparation device to make a test sample was disclosed. This device included a container with an insert on each end. The inserts have a portion that protrudes into the container. When test material is added to the sample preparation device, a groove was formed in test sample. These grooves reduce the amount of boundary effects that are present during testing.

A system and method for performing bond strength testing was also disclosed. In this system, a test sample was formed using the sample preparation device. This is placed upon a support and a half-spherical force applier is placed on top of the test sample. A press is used to apply force to the force applier and indirectly to the test sample.

A solid pharmaceutical dosage form testing apparatus and a method are presented. The solid pharmaceutical dosage form testing apparatus includes a striker component, an impact platform, a sensor data acquisition system, and a solid dosage form placement mechanism. The solid dosage form placement mechanism has first and second push components that are movable toward each other to position a solid dosage form at an impact site. The method includes performing an impact strike test on a first plurality of solid dosage forms, and measuring a plurality of peak impact force values. The method may include performing a drop test on a second plurality of solid dosage forms, and measuring a plurality of physical defect rates. The method may include determining a model that describes a relationship between peak impact force values and physical defect rates, and determining, based on the model, a predicted physical defect rate.

An apparatus for thermal ablation testing is provided. The apparatus comprises: a chamber; an optically transparent window in the chamber; a sample holder inside the chamber; a test sample in the sample holder; a number of bare-wire thermocouples connected to the test sample, wherein the thermocouples generate temperature data in the form of voltage; a mass balance inside the chamber, wherein the mass balance is configured to hold the sample holder and dynamically detect changes in mass of the test sample; an external radiant heat source configured to heat the test sample through the window; and a pyrometer directed at the test sample.
