    • A process and system for obtaining a thickness swell measurement of a wood composite material sample. The process includes placing a measurement pattern on an edge of a wood composite material sample, the measurement pattern including layers having a thickness; measuring the thickness of at least one of the layers of the measurement pattern prior to exposing the wood composite material sample to a thickness swell-inducing condition; exposing the wood composite material sample to a thickness swell-inducing condition; and re-measuring the thickness of the at least one layer after exposing the wood composite material sample to a thickness swell-inducing condition to thereby obtain a thickness swell measurement for the wood composite material sample. Representative wood composite materials include medium density fiberboard (MDF), oriented strandboard (OSB) and particle board.
    • 用于获得木材复合材料样品的厚度膨胀测量的方法和系统。 该方法包括将测量图案放置在木材复合材料样品的边缘上,测量图案包括具有厚度的层; 在将木材复合材料样品暴露于厚度膨胀诱导条件之前,测量测量图案的至少一层的厚度; 将木材复合材料样品暴露于厚度膨胀诱导条件; 并在将木材复合材料样品暴露于厚度膨胀诱导条件之后重新测量至少一层的厚度,从而获得木材复合材料样品的厚度溶胀测量值。 代表性的木材复合材料包括中密度纤维板(MDF),定向刨花板(OSB)和刨花板。
