GB/T 13436-2008 in English

《GB/T 13436-2008扭转振动测量仪器技术要求》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。
本标准自实施之日起代替GB/T 13436-1992。本标准规定了内燃机轴系的扭转振动测量仪器的分类、技术要求以及包装、标志和贮存等。本标准适用于测量内燃机轴系扭转振动的角振幅、频率、轴段扭矩或应力等物理量的仪器。测量其他类型轴系扭转振动的仪器亦可参照使用。本标准是对GB/T 13436-1992《扭转振动仪器技术要求》的修订。
本标准与GB/T 13436-1992比较，主要技术变化如下：
―――对扭振仪的分类做了重新规定，将激光扭振仪并入模拟式电测扭振仪，增加了数字式电测扭振仪和扭振应力测量仪；
―――增加了对数字式电测扭振仪和扭振应力测量仪的技术要求；
―――删减了附录Ｂ扭振仪幅频特性。

Scope

This standard specifies the classification, technical requirements, packaging, marking and storage of torsional vibration measuring instruments for internal combustion engine shafting (hereinafter referred to as torsional vibration instruments). This standard applies to instruments for measuring physical quantities such as angular amplitude, frequency, shaft torque or stress of internal combustion engine shafting torsional vibration. Instruments for measuring torsional vibration of other types of shafting can also be used as a reference.
