标准摘要
[中文适用范围]： 本文件规定了一种通过高温下振动脉冲激励测定矩形截面棒材和圆形截面耐火材料试样动态杨氏模量的方法。 动态杨氏模量是利用样品在弯曲振动模式下的共振频率来确定的。 本文件不解决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。 [外文原描述]： 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.
