Martindale Abrasion Tester For Testing Lab

Martindale Abrasion Tester - For Testing Lab 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. One of the standard equipment used for this determination is the Martindale Abrasion Tester. 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. civil lab equipments manufacturers
