• Data

  Model	Abrasive Action	Examples of Material Tested	Notes
  Calibrase® Abrading Wheels
  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.
  Calibrade® Abrading Wheels
  H-38	Mild	Woven and non-woven fabrics	Do not exceed 500g load; reface with multi-point diamond tool
  H-10	Mild - Medium	Steel and ferrous alloys (including the effect of hardening and tempering treatments)	Reface with single-point diamond tool
  H-18	Medium - Coarse	Rubber (non-tacky), woven textile fabrics, coated fabrics, flexible plastic sheet	Reface with single-point diamond tool
  H-22	Harsh	Rubber, linoleum, leather, automobile floor coverings, concrete	Reface with single-point diamond tool
  NOTE: Calibrade wheels should be refaced with Wheel Refacer and single point diamond tool, except for H-38. Calibrade wheels do not have an expiration period. Custom formulations available.
  Specialty Wheels and Abradants
  CS-0/S-32	Rubber (non-abrasive)	Dental pastes, cleaning powders	Do not use after expiration date; clean with isopropyl alcohol
  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-24	Aluminum (non-abrasive)	Resilient materials, coated abrasives	Clean with isopropyl alcohol
  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%

Correction Equation

In order to enable manufacturers and test laboratories to determine the abrasion resistance and a statement of conformity, the convenors of the EPLF Technical Working Group and CEN/TC 134/WG 9 recommend following the recommendation of Taber Industries under the current circumstances and correcting the determined test results by means of correction factor K.

The correction factor K shall be determined as follows: K = (Determined zinc abrasion rate according to ISO 24338 section 6.4 in mg / 100 mg) The zinc abrasion rate shall be determined at a height of (7.5 ± 0.5) mm above the test specimen holder (ISO 24338, Fig. 3, Key 4) by placing the zinc plate on a rigid and flat surface. This ensures that correction factors similar to those of real laminate flooring are achieved, as proven by studies. It is recommended to determine the zinc abrasion value of at least three pairs of sandpaper strips and to average the result. The correction factor K shall be multiplied by the test result.
