Texture Analysis in Action: Friction Testing

Horizontal Friction System fitted to the TA.XTplus Texture AnalyserStable 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.

Coefficient of Sliding Friction Rig fitted to the TA.XTplus Texture Analyser 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.
