The Testing Times

Tinius Olsen’s HT19 split collet chucks grip is designed for applications involving smaller turned dumbbell test specimens. The HT19 has a number of options to accommodate various size dumbbells with each split collet chuck set matched to a particular dimension of specimen. The HT19 grip a maximum capacity of 20kN and should not be used with a loadcell smaller than 50N capacity. Key parameters include diameter of turned gauge length, diameter of larger turned end section and the radius of the shoulder joining the end section and the gauge length. Tinius Olsen has higher capacity options for more traditional size specimens, so to learn what options are available for your application, please contact us.

PT190 is a 90 ° peel unit comprising of one HT50 ultra-light vice grip ( as standard) and a "horizontal Test bed". It is specifically designed for peel testing of the bond between copper and Printed Circuit Boards (PCB’s) as well as other laminate/layer bonded specimens, but can be used in a host of other peeling type applications. The PT190 is typically installed on a Tinius Olsen H5KS , or similar low capacity tensile tester and has a maximum capacity is 1.5kN (300lbf) with a minimum load cell of 50N. Prepared samples (150x50mm max.) are held on the test bed using a clamp with one end of the specimen inserted into the top clamp. The test bed incorporates a moving sled, mounted on precision bearings, which is directly attached to the moving crosshead of the test frame. As the crosshead moves up, the bad is pulled horizontally, so maintaining a peel angle of 90 ° throughout the duration of the test. To learn more about our grips and applications, please contact...

Tinius Olsen specifically developed the HT58 lightweight pneumatic grip for easy and repeatable thread/yarn testing. Designed for use with 10N load and calibrated for use between 10-1000 grams, the HT58 is used on the Tinius Olsen H5KS tensile tester. With a gripping pressure of 150N (15kgf), the HT58 eliminates the slip and its unique gripping face design prevents premature specimen breaks in the jaws. Its design allows quick and easy loading, for continuous commercial testing and accurate setting for repeatable gauge length choice.
