The Testing Times

When using Tinius Olsen higher capacity hydraulic wedge grips there is a quick way to implement lower capacity specimen grips while leaving the hydraulic grips in situ on the materials testing machine – The simple solution is an adapter model QS4860 which is held in the hydraulic wedge grips top and bottom from which smaller grips can be mounted; QS4860 120kN Hydraulic Grip Adapter to facilitate mounting of lower capacity grips. ( 50kN Max) below the hydraulic grips. Compatible with M16 (F) threaded interface ¾” male

Compression Lap Shear tests on small parts require a simple but exacting solution to successfully hold the component or material under test, especially if the parts are perhaps glass bonded to a substrate.   At Tinius Olsen we have such a solution, a compression grip system that allows the specimen to be held accommodating the need for adjustable off centre loading depending on the thickness of the test specimen in its shear configuration. Critically the solution maintains perfect alignment throughout the test so no extraneous side forces are exerted ensuring the shear strength attained is precise and accurate. Pictured adjustable compression shear grips capable of accommodating test specimens up to 25mm wide. 0.5mm to 3mm thickness Compatible with Tinius Olsen ST series of Tension/Compression materials testing machines Force capacity 0.001N up to 500N

Our new model 25ST is a 25kN (2500kgf, 5000lbf) tension compression materials testing machine, but more than that, this new series of machines have been designed as building blocks on which to build up truly universal materials testing systems, this means   the machine is a technology block within a competent system which may include a range of extensometers (strain measurement devices), temperature chambers or tanks filled with liquid in which a material can be tested, other test environment measurement and recording devices be it for movement, force, temperature, alignment and various levels of automation in support of efficient test throughput. In support of this building block concept these machines have a clear working area, no switches, buttons etc limiting location and implementation of accessories and devices, multiple T slots on the machine upright columns from which to anchor accessories, multiple high speed I/O ports for device connection, wireless user interface capab
