标准范围

本文件规定了通过在干燥和潮湿条件下切割胶合线来评估制造厂内胶合层压木材表面和边缘粘合效果的方法。不打算将其用于首选循环分层或块体剪切的初始型式试验。其原理是，如果满足最小木材破坏百分比，则粘结强度超过垂直于底层基材的颗粒拉伸强度，因此粘结不是限制集成材组件完整性的薄弱因素。

This document specifies methods of evaluating the effectiveness of glued laminated timber face and edge bonds within a manufacturing plant by cleaving of the glue line in both dry and wet conditions. It is not intended that it be used for initial type testing where cyclic delamination or block shear is preferred. It is based on the principle that, provided minimum wood failure percentages are met, then the bond strength exceeds the perpendicular to the grain tension strength of the under-lying substrate and therefore the bond is not the weak element limiting the integrity of a glulam assembly.
