在日本的8个地点进行了为期7年的室外暴露试验，调查了建筑用刨花板的退化情况。对两种不同防水性能的刨花板进行了试验，研究了其断裂模量、内粘结强度、抗侧钉性能等力学性能的劣化情况。为了消除木板劣化的区域差异，并使暴露在不同气候条件下的木板劣化因素标准化，我们引入了风化强度（WI），该强度由月降水量乘以月平均温度定义。通过相关分析考察了该因素的显著性。研究了与木材耐久性相关的三个常规气候指标，分析了它们对刨花板劣化WI的意义。结果表明，我们对风化强度的定义是最准确的，并且通过对世界上几个不同地点的回归分析，计算出了使初始抗弯强度降低一半的暴露期。
The deterioration of particleboards for construction use was investigated by outdoor exposure tests at eight sites in Japan over 7 years. Two types of particleboard with different water resistances were tested and the deterioration of mechanical properties such as modulus of rupture, internal bond strength and lateral nail resistance was investigated. In order to eliminate regional differences in the board deterioration and also to standardize a deterioration factor for the board exposed to varying climate conditions, we introduced the weathering intensity (WI) defined by monthly precipitation multiplied by monthly average temperature. The significance of this factor was investigated by correlation analysis. Three conventional climate indexes relevant to the durability of wood were also investigated to analyze their significance to WI for particleboard deterioration. It was found that our definition of weathering intensity was the most accurate and the exposure period that reduces initial bending strength by half was calculated by the use of regression analysis for several different sites worldwide.
