The treatment variable, TTM (kg/m), varied by increasing the tunnel run time while maintaining a constant rate of introduced abrader.
An example of angle abrader test results is shown in figure 3, which is a plot of wheel weight as a function of time.
He said that F 2357, "Test Method for Determining the Abrasion Resistance of Inks and Coatings on Membrane Switches Using the Normal Tool 'RCA' Abrader," from Committee F01 on Electronics, describes the apparatus and covers its use.
Abrasion by saltating sand grains was determined by weight loss/weight of abrader.
In the upper level of layer 3 were an elongated abrader (Figure 15 b), another part of a separate abrader (Figure 16 c), two basalt cores (Figures 18 l-m), a polished flake (Figure 18 c) and worked stones (Figures 16 a and 17 b,d,e).
The substrate is the steel panel recommended for the Taber abrader.
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.
Three non-ceramic artefacts, an abrader made in volcanic tuff, a piece of worked ironstone and a chert flake were found.
Uncured specimens for the drum abrader, flexometer and Zwick rebound tests were prepared by cutting disks from flat sheets and plying up sufficient layers to fill the cavities in multi-cavity molds for curing.
They include pearlshell fishhooks and manufacturing debris, basalt debitage, a coral abrader, a nearly complete cowrie (Cypraea) shell vegetable peeler, a drilled sea mammal tooth, and cut bone.
