Built on a combination of the RCA Abrader design, and the Finger Pressing design of the Pneumatic Finger Tester, this Wet Abrader adds the ability to apply a liquid to a special NTI Abrasive Media. This abrasive media is then pressed and rubbed against the specimen using a silicone finger probe. The test probe conforms to ASTM 1578 and ASTM 1597 Fig. 1.
This abrader can test the abrasion resistance of inks and coatings on a variety of items including membrane switches, silicone keypads, computer keys, buttons, or any item that is repeatedly pressed or in contact with the human finger in a wet or dry state. This abrasion wear tester can also help support the test standard ASTM 1597 “Determining the Actuation Force and Contact Force of a Membrane Switch”.
The Norman Tool Wet Abrader Tester is warranted against failure due to materials and/or workmanship for a period of six (6) months from date of delivery.
