|CS-8||Extremely Mild||Labels||Do not exceed 500g load; reface with S-11 disc|
|CS-10F||Very Mild - Mild||Safety glazing, transparent plastics||Do not exceed 500g load; reface with ST-11 refacing stone|
|CS-10||Mild - Medium||Organic coatings, plastics, textiles, leather||Reface with S-11 disc|
|CS-10W||Mild - Medium||Textiles||No colorant, eliminates color transfer from the wheel to the specimen; reface with S-11 disc|
|CS-17||Medium - Harsh||Anodized aluminum, powder coatings, ceramics, plastics and enamels||Reface with S-11 disc|
|NOTE: Shelf life is dependent on proper storage conditions: temperature = 23 °C ±2 °C, relative humidity = 50% ±5%. Calibrase wheels should be refaced with S-11 disc, except for CS-10F. Do not use AFTER expiration date. Custom formulations available.|

|CS-5||Wool Felt (dense)||Textile fabrics (when the service wear requires one fibrous material to rub against another)||Do not exceed 500g load|
|S-33||Sandpaper Strips||Vitreous and porcelain enamels, paints, metallic coatings, furniture surfaces||Use with CS-0 wheels; 12.7 x 160 mm strips include adhesive; P320A FEPA aluminum oxide (avg. particle 46.2µm) closed coat on "A" weight paper (70 - 100 g/m2)|
|S-42||Sandpaper Strips||High pressure decorative laminates, wood flooring, plastics, furniture surfaces, paints and varnishes||Use with CS-0 wheels; 12.7 x 160 mm strips include pressure sensitive; 180 ANSI-CAMI aluminum oxide (avg. particle 78µm) open coat on "A" weight paper (70 - 100 g/m2)|
|NOTE: Sandpaper should be stored and conditioned in a controlled environment: temperature = 23 °C ±2 °C, relative humidity = 50% ±5%|
Depending on the abradant type and test specimen, the wheel surface may change (i.e. become clogged) due to the transfer of material from the test specimen to the abrading wheel, and must be cleaned at frequent intervals. How long a set of Genuine Taber Wheels will last is dependent on the load, surface texture and frictional characteristics of the material being tested and frequency of refacing.
Most published test methods provide sufficient details on which abrasive wheels to use. If you are following a particular standard, please refer to it for the appropriate wheel. If your application is not covered by an established procedure, deciding which abrading wheel is best determined with preliminary testing on the actual material. The ideal selection criterion is to reproduce, as nearly possible, the wear which the material will be subjected to in actual use. It is important to keep in mind that wear is a complex phenomenon that may not be exactly replicated through an accelerated abrasion test, and the abrasive wheels represent a limited subset of actual contact conditions that material surfaces will be subjected to while in service.
Load references are per arm. By itself, the abraser arm provides a standard load of 250 grams on the wheel. Using the auxiliary weights, standard wheel loads of 500 or 1000 grams can be obtained. Please note, the markings on the auxiliary weights are NOT reflective of the actual mass of the additional weight. The auxiliary weights are marked with the TOTAL load that will be exerted on the wheel and equals the combined mass of the abraser arm and auxiliary weights. The weight marked 500 gram is actually 250 grams and the weight marked 1000 gram is actually 750 grams.
