A test method for determining impact effects and abrasion effects of particles such as rain, hail, dust, ice, sand, and micrometeoroids at speeds above Mach, i.e., higher than the speed of sound. The test method includes the steps of placement of balls in capsules, firing the capsules with a rifle firing system, hitting of the fired capsules and/or the balls to a target inside a firing range, recording the impact effects during a firing with a recording system, determining a durability and a lifetime of a test sample of test samples by calculating a number of the balls hitting the target and a number of shots providing an effect.
