标准范围
在不同温度下,特别是在0°C以下,测定扭转刚度的通用方法规范。在任意固定的荷载施加时间后,使用规定的试验装置,观察扭矩和偏转角度。该程序在单一温度下使用,或在为待测材料规定的范围内,在选定的温度间隔内使用。扭转刚度表示为每个温度下的表观扭转弹性模量。
Specification of a general method for the determination of the stiffness in torsion at various temperatures, particularly below 0 °C. An observation of torque and angle of deflection is made after an arbitrarily fixed time of load application, using the specified testing apparatus. This procedure is employed at a single temperature or at selected temperature intervals over a range specified for the material to be tested. The stiffness in torsion is expressed as the apparent torsional modulus of elasticity for each temperatur.
