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。 本文件不涉及与其使用相关的安全问题。本标准的使用者有责任建立适当的安全和健康实践。

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. This document does not address the safety issues associated with its use. It is responsibility of the users of this standard to establish appropriate safety and health practices.
