The Testing Times

The Compression of a spring can be quite a hard thing to measure, the spring has a tendency to want to exert it's applied force horizontally to the platens (in other words, fly off under the nearest table...) This isn't really a problem, just a nuisance and in some applications a desirable feature of springs... To stop the test sample from flying off these compression platens have a free running guide that retracts into the top body. This holds onto the spring, whilst having a known affect on the test.

All of the testing grips and attachments listed here have a specific use. For example the Insulation Grip is designed to be used with insulation materials, but it can equally work just as well with any fibrous material. We often review or re-use previous designs because we know that they work and have been proved to be successful in the field. The staff here have an encyclopedic knowledge of over 2,000 Bespoke products and custom test fixtures we've produced over the years, and are continuing to produce on a daily basis. Basically, if you need to test something, and you require help call Tinius Olsen ...

To improve usability we have extended the range of insulation grips to include a screw based closing mechanism. This gives the ability to close the grip like a vice and so you are relying on the mechanical advantage provided by the screw rather than by the lever, this can offer more control of the sample alignment and help prevent a jaw break... There are interchangable teeth, depending on requirements.
