Abrasion Tester, Martindale

Globe Enterprises offers Martindale Abrasion Tester. Determination of resistance of any fabric to abrasion is usually carried out by abrading the fabric under specified conditions against a standard abradant. Although plane abrasion of fabric surface does not cover all aspects of strains that are important in determining service life, there are occasions when such a test gives useful information. The Martindale abrasion tester is one of the standard equipments used for this determination. This apparatus gives a controlled amount of abrasion between fabric surfaces at comparatively low pressures in continuously changing direction. Circular specimens of fabric are abraded under known pressures under a motion, which is the resultant of two simple harmonic motions at right angle to each other. The resistance to abrasion is estimated by visual appearance or by finding the loss in mass of the specimens. The force on the test specimens can be altered by adding or removing dead weights from the specimen holders. A five digit electronic pre-set counter counts the number of rotation of outer pegs and stops the motor automatically after a pre-set numbers of rotations. Templates for marking the test specimens and abradant, disc weights to keep them flat during fixing, and mounting jig for test specimens are provided as standard accessories. The various components are mounted on a sturdy fabricated steel base and are finished in shore blue metallic painting and bright chrome or zinc plating to give them a corrosion resistant finish.
