GB/T 13824-2015 in English

《GB/T 13824-2015旋转与往复式机器的机械振动 对振动烈度测量仪的要求》由TC53（全国机械振动、冲击与状态监测标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准规定了在机器壳体上,特别是特定机器趋势监测所做重复测量的不确定度不超过规定值时,振动烈度测量仪应满足的要求。
本标准适用于直接显示或记录其测量单位已定义为振动速度均方根(r.m.s.)的仪器。
注1:附录 A 中给出了检查真有效值显示的方法,保留这一方法主要是针对不基于现代模数转换和均方根数值计算的仪器,但该方法同时也适用基于此的仪器。
注2:在所规定的测量频率范围内,这些仪器也可以用于测量精度相近的其他场合,例如结构、隧道、桥梁等振动速
度的测量,也可以包括相位测量选项。

Scope

This standard specifies the requirements that the vibration severity measuring instrument should meet when the uncertainty of repeated measurements made on the machine shell, especially the trend monitoring of a specific machine, does not exceed the specified value. This standard applies to instruments that directly display or record the unit of measurement for which vibration velocity has been defined as the root mean square (rms). Note 1: The method for checking the true RMS display is given in Appendix A. This method is reserved mainly for instruments that are not based on modern analog-to-digital conversion and root-mean-square numerical calculations, but this method is also applicable to instruments based on this. Note 2: Within the specified measurement frequency range, these instruments can also be used in other occasions with similar measurement accuracy, such as the measurement of vibration velocity of structures, tunnels, bridges, etc., and can also include phase measurement options.
