The present study analyses the moisture performance of nine wood species and wood-based materials determined in various laboratory and field trials to identify the method with the highest predictive power and determine the correlation between respective measurements. The moisture performance of wood and wood-based products has been recognised (besides inherent wood resistance) as the second most important parameter contributing to wood service life in above ground applications. Therefore, it is of great commercial importance to understand this phenomenon. In-service moisture monitoring trials can be unacceptably long, but on the other hand, they provide more realistic test conditions than laboratory tests. However, experiments in laboratory conditions enable a high level of reproducibility and are much faster than in-service tests. In order to assess the correlation between various tests, Pearson product moment correlation coefficients were calculated to determine the level of the strength of the linear relationship between the in-service and laboratory trials. Within this paper, it was attempted to identify laboratory methods suitable for quantification of moisture content during outdoor exposure.

在实验室和野外试验中确定的木材的湿气性能研究

本研究分析了在各种实验室和田间试验中确定的9种木材和木材基材料的湿气性能，以确定具有最高预测能力的方法并确定各个测量值之间的相关性。木材和木质产品的湿气性能（固有的木材抗性）已被公认为是提高地面应用中木材使用寿命的第二重要参数。因此，了解这种现象具有重要的商业意义。使用中的水分监测试验时间可能会长得令人无法接受，但另一方面，它们提供的试验条件要比实验室试验更为实际。但是，在实验室条件下进行的实验可实现较高的可重复性，并且比在用测试快得多。为了评估各种测试之间的相关性，计算了Pearson产品力矩相关系数，以确定在役和实验室试验之间线性关系的强度水平。在本文中，试图确定适合量化室外暴露期间水分含量的实验室方法。
