    Utilizando el test de impacto, ASTM D1037-99, se compara la resistencia de diversas composiciones de fabricación de parquet multicapa de Eucalyptus globulus y Quercus robur, con distintos espesores de capa noble y utilizando para cada uno de ellos tres tipos diferentes de soporte base con el propósito de evaluar la aptitud de Eucalyptus globulus como parte destacada (capa noble) en la elaboración de un parquet multicapa.

    El resultado del ensayo de impacto resultó ser estadísticamente independiente de la especie utilizada (eucalipto o roble) como capa noble, habiéndose analizado con niveles de significación superiores al 95%, siendo, sin embargo, dependiente del tipo de elemento de soporte utilizado y del espesor de la capa noble.

    Un modelo lineal, que utiliza la densidad media en los 4 primeros milímetros de profundidad de cada pieza, permitió explicar hasta un 82% de la variación  del diámetro de huella en el ensayo de impacto, lo que permite utilizar con suficiente garantía esta densidad como predictor del diámetro de huella del ensayo de impacto.

    The resistance of several Eucalyptus globulus and Quercus robur engineered wood flooring compositions has been tested using the impact test, according to the ASTM D1037-99 standard. The test samples were made up  of different top layer, top layer thicknesses and different inner lays. The result not showing significant differences between the two wood species.

    The impact test result was statistically independent of the species tested (eucalyptus or oak) as top layer, being analyzed with significance levels above 95%; however, statistically significant results were obtained for support material and top layer thickness.

    A linear model, using the average density on the first 4 mm depth, explained 82% of the impact results obtained by the tests, that allow to use, with sufficient guarantee, this average density as a good predictor of the results (diameter of impress mark) of the impact test.
