本文件规定了一种通过高温振动脉冲激励测定耐火材料矩形截面钢筋和圆形截面试样动态杨氏模量的方法。动态杨氏模量由试样在弯曲振动模式下的共振频率确定。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document specifies a method for determining the dynamic Young's modulus of rectangular cross-section bars and circular cross-section specimens of refractories by impulse excitation of vibration at elevated temperature. The dynamic Young's modulus is determined using the resonant frequency of the specimen in its flexural mode of vibration.All current amendments available at time of purchase are included with the purchase of this document.
