Bamboo structures — Engineered bamboo products — Test methods for determination of mechanical properties using small size specimens 竹结构工程竹制品用小尺寸试样测定机械性能的试验方法
发布日期: 2023-12-12
本文件规定了使用小尺寸试样的试验方法,适用于测定工程竹制品的以下机械性能:平行于纤维的拉伸强度;平行于纤维的拉伸模量;平行于纤维的抗压强度;垂直于纤维的拉伸强度;垂直于纤维的拉伸模量;垂直于纤维的抗压强度;垂直于纤维的压缩模量;平行于纤维的剪切强度和平行于纤维的剪切模量。 笔记?本文件提供了ISO 23478的替代测试方法。 本文件规定了3.1和3.2中定义的当前生产产品的测试程序,以评估材料特性。本文件中规定的方法适用于小尺寸试样。确定群体机械性能的特征值、设计值或允许值所需的方法超出了本文档的范围。不符合竹材或胶合层压竹材定义的材料超出了本规范的范围。

This document specifies test methods, using small size specimens, suitable for determining the following mechanical properties of engineered bamboo products: tensile strength parallel-to-fibre; tensile modulus parallel-to-fibre; compressive strength parallel-to-fibre; tensile strength perpendicular-to-fibre; tensile modulus perpendicular-to-fibre; compressive strength perpendicular-to-fibre; compressive modulus perpendicular-to-fibre; shear strength parallel-to-fibre and shear modulus parallel-to-fibre.

NOTEThis document provides an alternative test method to ISO 23478.

This document specifies test procedures for currently manufactured products as defined in 3.1 and 3.2 to evaluate material properties. The methods specified in this document are applicable to small size test specimens. The methods required to determine characteristic values, design values, or allowable values of the mechanical properties for a population are out of the scope of this document. Materials that do not conform to the definitions of bamboo scrimber or glued-laminated bamboo are beyond the scope of this specification.
