Determination of the resistance to low‑stress scratching abrasion by the dry‑sand rubber‑wheel test according to ASTM G65 (Standard Test Method for Measuring Abrasion Using the Dry Sand/Rubber Wheel Apparatus): a flat, rectangular test specimen is pressed against the rim of a rotating rubber wheel with a defined normal force, and a controlled flow of the dry, angular silica sand is introduced into the contact zone. The mass loss after a specified number of the wheel revolutions is measured, and the volume loss in the cubic millimetres is calculated. This high‑strength wear‑resistant material testing service provides the primary comparative ranking of the steels, the cast‑irons, the hard‑facings and the coatings for the dry, the sandy environments such as the mining, the agricultural and the earth‑moving applications.
Wet‑sand rubber‑wheel abrasion test according to ASTM G105 (Standard Test Method for Conducting Wet Sand/Rubber Wheel Abrasion Tests): a slurry of the standardised quartz sand and the water is dripped into the contact zone, reproducing the three‑body, the low‑stress abrasion that occurs in the slurry pumps, the dredge pipelines and the wet‑screening applications. The mass and the volume loss are reported, and the results are compared with the dry‑sand data to determine the sensitivity of the material to the presence of the water and the corrosion‑enhanced wear.

The erosion‑rate in the cubic millimetres per gram of the erodent is reported, and the erosion‑rate‑versus‑impact‑angle curve is constructed, identifying the ductile or the brittle erosion mechanism of the material.
Slurry‑jet and the liquid‑solid erosion testing according to the internal validated protocol: the high‑pressure pump forces a slurry of the water and the standardised sand or the customer‑supplied mineral through a nozzle, and the jet impinges on the test specimen at a controlled angle and velocity, simulating the erosion of the slurry‑pump liners, the pipe bends and the hydrocyclone walls.
Influence of the abrasive‑particle size, the hardness and the shape on the wear‑rate: the abrasion or the erosion test is repeated with the several abrasive‑types and the size‑fractions, and the wear‑rate map is constructed, providing the data that the materials‑engineer uses to select the optimum wear‑protection material for the specific mineral‑processing or the bulk‑material‑handling application.
