The examination of thickness(t) is measured in the four corners of the flooring, and the midpoint

of the long side of the flooring (20mm away from the flooring side) by micrometer, the precision is 0.1mm

3.1.2.4 Examination of squareness (q)

For measuring the squareness (q), one side of L-square abuts against the long side of the flooring, and the maximum distance from the other side of the L-square to the terminal of the flooring is measured

by clearance gauge, the accuracy is up to 0.01mm
