* The following suggestions are provided as a starting point for using the Taber Rotary Abraser to evaluate different materials. With the exception of the CS-5, the abrading wheels should be refaced prior to each test (based on the manufacturers recommendations) and a consistent vacuum nozzle height should be used (measured off the specimen surface). Other factors to consider include specimen conditioning, environmental conditions, vacuum suction level, specimen cleaning, and test cycles.

Paper and Cardboard � Abrasion Resistance

Specimen: 4 inches diameter or square with ¼ inch center hole for sufficiently rigid materials; for flexible materials, 4 inches round or square with ¼ inch center hole mounted on S-36 or S-36-1 Mounting Card
Wheels and Load: CS-10 Calibrase with 250 gram or 500 gram load
Evaluation: Visual changes (i.e. loss of luster; changes of surface; etc.); weight loss method
Remark: Duration of the test is a predetermined number of cycles (i.e. 100, 300, 500 or whatever number is needed to reach the degree of wear to be regarded as the end point of the test). The loss in milligrams is calculated on a 1000 cycle basis which gives a Taber numerical wear index directly comparable with that of similar materials tested under the same conditions.

Paper � Erasure Tests

Specimen: 4 inches diameter or square with ¼ inch center hole, mounted on S-36 or S-36-1 Mounting Card
Wheels and Load: CS-10 Calibrase with 250 gram or 500 gram load.
Evaluation: Visual end point determined by partial erasure of ink marks from wear path surface
Remarks: The properties to be determined are: 1) ease of erasure, 2) amount of damage to surface from abrasion, 3) ability of specimen to accept rewriting after erasure, 4) number of times the specimen will accept erasure and rewriting. The specimen is prepared by writing or drawing circular lines on the surface to be tested using a permanent ink. The ink should be thoroughly dried on the conditioned paper before testing.

Paperboard � Scuffing Test

Specimen: 4 inch diameter or square
Wheels and Load: H-10, H-18 or H-22 Calibrade with 500 or 1000 gram load.
Evaluation: Visual end point determined by comparison of the degree of scuffing with that of a standard sample tested under identical conditions
Alternate Wheels and Load: CS-5 with 250 or 500 gram load.
Evaluation: Visual change in gloss

Labels

Specimen: Affix to glass or metal specimen plates
Wheels and Load: CS-10 Calibrase with 250 gram or 500 gram load
Evaluation: Visual changes (i.e. loss of luster; changes of surface; etc.); weight loss method
Remark: Duration of the test is a predetermined number of cycles (i.e. 300, 500 or whatever number is needed to reach the degree of wear to be regarded as the end point of the test). The loss in milligrams is calculated on a 1000 cycle basis which gives a Taber numerical wear index directly comparable with that of similar materials tested under the same conditions.

Wood

Specimen: 4 inches square with ¼ inch center hole for materials to ¼ inch thick, 3/8 inch center hole for materials ¼ to ½ inch thick
Wheels and Load: H-18 or H-22 Calibrade with 500 gram or 1000 gram load
Evaluation: Weight loss or depth of wear method
Remark: For specimens ¼ to ½ inch thick, use S-21 Extension Nut

General Notes

• To generate useful data, specimens must flat.
• To prevent wrinkling, flexible samples can be mounted to the S-36 or S-36-1 Mounting Card.
• The effect of moisture on the wear factor of wood, such as decking, can be determined by soaking the wood in water for a specified length of time and testing in that condition, using the rimmed specimen holder (E140-75). To subject specimens to a wet abrasion test, the Textile Holder, Tensioning Type for Wet or Dry Testing (E140-18) can be used. This holder is designed to give an initial stretch to woven fabrics so that they may be tested while moist with minimum tendency to wrinkle.
