Abrasion Testing Machine Dealers in Virar

STECH ENGINEERS DIN Abrasion tester (Abraser / Abrader), which is the original product developed in Germany and sold worldwide, is designed to conform to the ASTM D5963 and IS0 4649 standards (ISO 4649 has replaced the DIN 53516 standard). This top quality and highly popular abrasion tester will allow you to measure the abrasion resistance of rubbers (vulcanized thermo set rubbers and thermoplastic elastomers) that are subject to abrasive/frictional wear in their actual service, such as tires, conveyor drive belts, and shoe soles. Since wear is always a result of abrasion, different test methods have been developed for the simulation of long term wear.     The method conforming to ASTM D5963 / ISO 4649 has proven to be the best way of simulating long term wear. This method enables comparative tests for the control of the uniformity of a specific material. The achieved test results provide important parameters in respect to the wear of elastomers in practical use. The abrasion resistance is measured by moving a test piece across the surface of an abrasive sheet mounted to a revolving drum, and is expressed as volume loss in cubic millimeters or abrasion resistance index in percent. For volume loss, a smaller number indicates better abrasion resistance, while for the abrasion resistance index, a smaller number denotes poorer abrasion resistance. The DIN Abrasion tester can also be used for comparative measurements on other materials such as plastics, chalk or painted surfaces.   Accessories for DIN Abrasion Tester   Abrasive Sheet : An abrasive sheet will abrade approximately 210 ... 250 mg from the mass of a comparison sample. This abrasion should be reduced to approximately 210 ... 220 mg by abrading a steel sample across the entire width of the delivered drum once or twice. The sheet can be used as long as the abrasive loss of a comparison rubber sample is less than 180 mg. It has to be replaced then.       Rubber Comparison Sample Sheet : The rubber comparison sample sheet serves for the determination of the degree of abrasiveness in compliance with ISO 4649 (Formerly DIN 53516). It is produced of a special mixed rubber. Each plate has a dimension of approximately 186 mm x 186 mm and enables the production of about 100 comparison samples of a thickness of 8 mm.       Circular Cutting Unit : The circular cutting unit is used for the cutting of rubber samples with a diameter of 16 mm. The holder for the cutter is a morse taper No. 2 and can be fitted to a suitable drilling machine.       Replacement Cutter Spare cutter : For the circular cutting unit. Increasing the sample pressure by 10 N An additional weight of 10 N allows an increase of the pressure in steps by 12,5 / 15 / 17,5 and 20 N.       Drum Cleaning Unit : The drum cleaning unit consists of a set of brushes with holder, which is mounted on the rear of the sample holder and removes the dust from the abrasive sheet. A vacuum cleaner hose with a diameter of 40 mm can be connected to the brush holder.       Replacement Brushes : For the drum cleaning unit       Precision Balance : The precision balance with digital display, for the weighing of the sample, consists of a metal housing with a glass-protected weighing space. Weighing tray Ø 80 mm Weighing range: 0 ... 110 g Display step: 0,1 mg Reproducibility: ± 0,15 mg Linearity: ± 0,2 mg Mains connection: selectable 110/220 V, 50/60 Hz Dust Cover       Dust cover : Consists of a transparent plastic cover.
