Akron abrader

Champ et al. [47] devised a simple abrasion experiment by measuring the abrasion loss caused by a razor blade scraping under load across a mbber surface. For this an Akron abrader sample wheel was used. They used soft unfilled noncrystallizing mbber compounds based on different polymers. Under these conditions strong abrasion pattern develop. 

Abrasion under limited slip used to be, and to some extent still is, measured either with the standard Akron abrader or the Lamboum abrader. In case of the Akron abrader the sample runs under a slip angle at a constant load against the abrasive surface of an alumina grind stone. Speed and load are fixed the side force is not measured.

Akron and the improved Lamboume are distinctive for the ability to vary slip angle in a simple manner and the Schiefer for giving uniform multidirectional abrasion. Probably the most versatile commonly used apparatus is the Taber because of the very wide range of abradants readily available and its ability to operate with lubricants. The LAT 100 is in a class of its own as regards sophistication and features. 

All of the abraders developed for rubber testing, the Akron, DuPont, Dunlop etc, were primarily aimed at testing tyre compounds. Noboru Tokita at al83 have discussed tyre wear testing and point out that it is virtually impossible to simulate the total wear pattern and to determine tread life from laboratory abrasion testers, but many people have tried. The LAT 100 approach using multi conditions would seem to stand the best chance.
