Abrasion and wear testing machine BYK Gardner USA

Coated and uncoated surfaces need to be tested for resistance to abrasion caused by a brush, sponge, or other means. Examples for testing include interior paints, wall coverings, carpets, floor tiles, polishes, bath tubs, shower stalls, and furniture.

Abrasion instruments producing repeated small-scale patterns of damage caused by attrition or erosion under controlled conditions simulate best everyday use or wear patterns. The rubbing method may also be used to test efficiencies of detergents or cleansers or to test the durability of an abrading or cleaning device such as a scouring pad.

The BYK-Gardner Abrasion Tester helps evaluate washability and abrasion resistance of a material. The tester reciprocates an abrasive force linearly over the sample.
- Reciprocating linear motion at 37.0 ±1 cycles per minute with a constant speed over a 10 inch travel
- Utilizes a brush, sponge, or abrasive paper to simulate real life situations that must meet several standards
- Completely enclosed electrical and mechanical components - for dry or wet testing
- Preset count-down counter with automatic shut-off and standard cycle counter provided for versatile testing
- Heavy-duty drive system allows for easy maintenance and a long-life
- Meets ASTM D 2486

The drive mechanism consists of a gearhead motor driving the motor drive pulley gear. The rotary motion of this gear drives a smaller gear, the chain drive pulley, using a timing belt. The smaller gear drives a set of sprockets and continuous loop mechanism. The cable pair ends are attached to the virtual center of the chain, transforming the rotary motion of the chain into the reciprocating linear motion.
