FALLING SAND TEST FOR FAUCET SURFACE TREATMENT

Why some faucets finish will be fading off while some can be last for 10 years? The most important reason is that most of factories don't have the falling sand test. But our products have the professional sand dropping test standard as Kohler. The falling sand test is used to evaluate the abrasion resistance of the faucet’s coating. It mainly simulate the coating exposed to the outdoor wind and sand for a long time. The principle of this test is to let a certain size of gravel through a fixed internal diameter of the pipe from a specified height on the test plate until worn to expose the substrate. The sand consumed is then weighed and the test results expressed as standard sand per unit of coating thickness. Therefore, a good faucet must have withstood the test of strict sand falling test, and showed amazing abrasion resistance, then appears in front of you.
