Floor residual depression test machine Also known as floor residual indentation test machine, the test machine is a method that determines the residual depression of the elastic floor. After load, it is produced on elastic or thin -piece floor coating. The difference between the initial thickness and the thickness measured after the loading, in the specified loading capacityThe distance between the two parallel boards is used with the lower shop material.The sample is subject to static static, and the thickness before the force is measured and the thickness after the recovery period. fT5Textile Testing Instruments, Testing Equipment Manufacturer
