Floor Misunderstanding 1: Using a key to measure the floor's wear resistance

More than one salesperson, when demonstrating the high quality of their brand's floor panel finish, chose to use a key to scratch back and forth on the surface of the panel, and then pointed out to the reporter that there were no marks on the floor. Additionally, the salesperson used a marker to write on the surface of the floor and easily wiped it off with a cloth to prove that the panel has good stain resistance.
Expert analysis: There are clear requirements in national standards for the wear resistance and stain resistance of the board surface. Experts say that the demonstration made by the salesperson is actually the minimum performance that the surface of the board should have, and cannot explain the problem. Because in actual testing, the testing methods and conditions are much more stringent.
