BS ISO 13586:2018规定了在规定条件下确定裂纹张开模式（模式I）下塑料断裂韧性的原则。定义了裂纹试样的两种试验方法，即三点弯曲试验和紧凑试样拉伸试验，以适应不同类型的可用设备或不同类型的材料。交叉引用:ISO 604ISO 7500-1ISO 527-1ISO 9513ISO 2818ASTM D5045-14ASTM E399-12ISO 291购买本文件时提供的所有现行修订版均包含在购买本文件中。

BS ISO 13586:2018 specifies the principles for determining the fracture toughness of plastics in the crack-opening mode (mode I) under defined conditions. Two test methods with cracked specimens are defined, namely three-point-bending tests and compact-specimen tensile tests in order to suit different types of equipment available or different types of material.Cross References:ISO 604ISO 7500-1ISO 527-1ISO 9513ISO 2818ASTM D5045 - 14ASTM E399 - 12ISO 291All current amendments available at time of purchase are included with the purchase of this document.
