Texture Analysis in Action: Friction Testing

Stable Micro Systems offers two options for Friction Testing attachments.

The HORIZONTAL FRICTION SYSTEM (A/HFS) comprises a support leg and levelling feet which are fixed to the Texture Analyser, so that the assembly can be laid in a horizontal position. 

A platform is fitted to the base on which a friction sled, which is attached to the loadcell, is constrained to slide over the sample.

Additional load may be provided by adding weights positioned centrally on the sled. This arrangement offers the advantage of measuring sliding friction in both directions and also during cycling. Typical applications include films, creams and packaging.

The COEFFICIENT OF SLIDING FRICTION RIG (A/FR) is used to determine the static and dynamic coefficient of friction for plastic film and packaging materials. 

It meets the requirements of ASTM D 1894-90. It can be used to determine the friction characteristics of material sliding over itself as a reference material or other substances under specified test conditions.
 
The reference material is fixed firmly
to the base and the test material to the sled.
This sled is 63.5 x 63.5mm and weighs
200 +/- 5g. The sled is pulled across the reference material at a constant speed and the force measured. 

The coefficient of friction is determined from these results.

We can design and manufacture probes or fixtures for the TA.XTplus texture analyser that are bespoke to your sample and its specific measurement.

Once your measurement is performed, our expertise in its graphical interpretation is unparalleled. Not only can we develop the most suitable and accurate method for the testing of your sample, but we can also prepare analysis procedures that obtain the desired parameters from your curve and drop them into a spreadsheet or report designed around your requirements.

For more information on how to measure texture, please visit the Texture Analysis Properties section on our website.

The TA.XTplus texture analyser is part of a family of texture analysis instruments and equipment from Stable Micro Systems. An extensive portfolio of specialist attachments is available to measure and analyse the textural properties of a huge range of food products. Our technical experts can also custom design instrument fixtures according to individual specifications.
