1. Check and ensure that the Taber abrasion testing machine and all necessary accessories, including vacuum cleaner, specimen, weights, abrading wheels, wrench, brush, etc., are in place.
  2. According to the specimen, please choose the right abrasive wheels, attach them to the pivoted arms, and tighten the knurled nuts to ensure that both are secured. Please note that there are resilient abrading wheels and vitrified abrading wheels. To achieve consistency of the test, the resilient wheels have to be refaced using a resurfacing disc(S-11) or sandpaper before every test and at intervals. For more details, refer to the specification in the standard cited. The vitrified abrading wheels don’t need this process.
  3. Weigh the specimen before being rubbed, and screw off bolts and take down the clamp ring from the specimen holder, then place the test specimen on the turntable in place (circular backing cardboard or a solid board equivalent to it is necessary to be padded beneath the specimen If the test piece is soft fabric), then screw up the bolts to fix the specimen.
  4. Lower the two grinding heads slowly and carefully until the wheels rest on the specimen, then check whether it needs to add loading weight based on different standards (weights of 250 g, 500 g & 750 g are available).
  5. Put down the ledge with vacuum pickup nozzles, adjust the position and vertical height above the surface of the test pieces according to the specification, and connect the vacuum machine to the Taber abrader, start the vacuum, and adjust the pressure to an appropriate value.
  6. Set the number of specimen revolutions and abrading speed, press the test button to start the machine.
  7. The machine will stop automatically once reaching the set number of cycles. You can brush the test piece and weigh it again to calculate the test result based on the specific method in the standard.

Please note: The above is a generic instruction for your reference. More test procedures in detail must follow the specific Taber abrasion test standards referenced.
