Descripción
The result of probing 228 pieces of 1000 x 50 x 22 mm of particle and medium density fibre boards are presented in order to establish a density estimation model based on the use of non-destructive and portable methods such as the Screw Withdrawal Resistance Meter, Pilodyn, ultrasound and stress wave vibration. For each class of board (particle or fibre board), we tested two types, standard board and humidity resistant board. In general terms, for each board class and type, the real density variation coefficients are much lower than these obtained in the non-destructive tests, so that regression models do not allow us to establish a suitable estimation, presenting very low determination coefficients. If the results are grouped according to whether boards are particle or medium density, for the second type we obtain a normal distribution, making it possible to establish statistical models linking actual board density and the results of non-destructive testing, with good correlation and determination coefficients. The best estimation tool in this case is ultrasonic wave velocity, which has a determination coefficient of almost 80%.
