What is "Vibration severity measurement instrument on the requirements 10816-3: 2009" ?

This standard is widely used for analysis of rotational machinery.
The current ISO standard 10816-3: 009 describes the absolute value judgment by velocity rms.

Objective machinery is classified into two major groups.

Group 1Large machinery : Output: 300 kW to 50 MW, Shaft hight: >315 mm

Group 2Medium machinery : Output: 15 kW to 300 kW, Shaft hight: 160 mm to 315 mm
