BS ISO 17281:2018规定了通过线弹性断裂力学（LEMF）方法确定裂纹张开模式（模式I）下塑料断裂韧性的原则和指南，荷载点位移率高达1 m/s。它补充了ISO 13586，以便将其适用范围扩展到略高于后一文件范围的荷载率。交叉引用:ISO 13586:2018ISO 291ISO 2818购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS ISO 17281:2018 specifies the principles and provides guidelines for determining the fracture toughness of plastics in the crack-opening mode (Mode I) by a linear elastic fracture mechanics (LEMF) approach, at load-point displacement rates of up to 1 m/s. It supplements ISO 13586 so as to extend its applicability to loading rates somewhat higher than is the case in the scope of the latter document.Cross References:ISO 13586:2018ISO 291ISO 2818All current amendments available at time of purchase are included with the purchase of this document.
