Plywood QC Inspection Checklist : Part 11 Simple way test the load-bearing performance
Tilt the plywood 45 degrees, then stand on the board and jump to test whether the structure of the board is reasonable, load-bearing performance and so on. If it is a plywood of furniture grade, a person of 50 to 60 kilograms usually jumps on the board for a few times. If there is no clicking sound coming from the inside of the board, the structure of the board can be simply judged to be very good. If there is a click sound inside the board, it indicates that the structure of the board or the materials used are not qualified. If it’s a film faced plywood or construction grade plywood, it takes 60 to 80 kilograms of people to jump on the board, usually tilting the board 40 degrees.
