The TTM (with units kg/m) is the sum of the total mass of introduced abrader
(TT[M.sub.in]) and the total mass of the sediment derived from the bed, or floor of the tunnel (TT[M.sub.bed]).

DIN abrasion tests frictional wear of a vulcanized elastomer, and therefore good performance of a material on the DIN abrader
may not be a good predictor for impact wear resistance of the compound.

With this precision speed control and encoder feedback, the DIN abrader
is said to deliver consistent results, insuring quality production, allowing supplier comparison and verifying advertised claims.

Figure 12 shows the abrasion resistance of all the compounds measured by the Pico abrader
, which provides a cutting abrasion resistance.

, " BFGoodrich, 1988.
Adams, a research archaeologist, details the analysis of ground stone tools like mortars and pestles, manos and metates, abraders
, polishers, and hammerstones, and artifacts shaped by abrasion or pecking, such as axes, pipes, figurines, ornaments, and architectural pieces, as well as other artifacts like stones used in cooking and heating, structural stones, and ecofacts.
Material from Aganoa and To'aga indicated that a variety of tools--including abraders
, fishhooks and scrapers--were made from shell.
These whetstones differ from more common abraders
(n = 529), which are made of much coarser-grained sandstone and have four to six grinding facets (Harp, 1964:Plate 20:2).

, pieces of a very abrasive red sandstone, that were ground square on one edge.
