本文件规定了使用此类基本元素对结构应用中的圆形或柱形竹子进行视觉和机械分类的分级程序。视觉排序基于工件的可观察特征。机械分类基于已知与定义等级的特征值相关的特性的无损测量。 本文件中的分级程序可用于质量验收制度，尽管本文件未定义或说明验收标准。 本文件仅适用于在干燥状态下分级的竹子。

This document specifies grading procedures for visually and mechanically sorting round, or pole, bamboo for structural applications using such fundamental elements. Visual sorting is based on observable characteristics of the piece(s). Mechanical sorting is based on non-destructive measurement of properties known to correlate to characteristic values defining a grade. The grading procedures in this document can be used in a quality acceptance regime, although this document does not define or address acceptance criteria. This document is applicable only for bamboo that is graded in the seasoned state.
