BS ISO 10817-1:1999

What is ISO 10817-1 - Rotating shaft vibration measuring systems about?

Since shaft vibration imposes additional load on bearings and coupling components, it is measured and monitored.

ISO 10817-1 gives details of how to obtain reproducible measurement results in order to enable the monitoring and evaluation of shaft vibrations according to the ISO 7919 series. As such, it is concerned primarily with the measurement of shaft vibrations for large machines (e.g., steam turbine generator sets, gas turbines, industrial turbosets, hydraulic machines).

ISO 10817-1 is applicable to radial vibration measuring systems on shafts, both for absolute and relative measurements. ISO 10817-1 covers the sensing device (i.e. transducer), signal conditioning, attachment methods and calibration procedures.

Who is ISO 10817-1 - Rotating shaft vibration measuring systems for?

ISO 10817-1 on Rotating shaft vibration measuring systems is useful for:

• Manufacturers and suppliers of engine / motor components 

Manufacturers and suppliers of large machines such as:

• Steam turbine generator sets
• Gas turbines
• Industrial turbosets
• Hydraulic machines

Users of large machines such as gas turbines, hydraulic machines etc. including:

• The aerospace industry
• The shipping industry
• The oil and gas industry
• Railways
• Electric power stations
• Product design teams / innovation teams
• Production / mechanical engineers
• Maintenance teams
• Quality control personnel

Why should you use ISO 10817-1 - Rotating shaft vibration measuring systems?

Powerful large machines such as turbines turn mechanical energy into electrical energy. Ships, trains, and airplanes are propelled by gas turbine engines; and the rotating shaft needs to function with minimal vibration to be effective in such machines.

A measuring system to evaluate the radial vibration of a rotating shaft can be thought of as consisting of several distinct subsystems. ISO 10817-1 illustrates the interrelationship of these subsystems via diagrams. ISO 10817-1 discusses sensing systems, measurement uncertainties, and environmental conditions while measuring the rotating shaft vibration.

ISO 10817-1 guides you with the calibration of the measuring systems. Measurement uncertainty limits for various conditions as well as temperature classes have been presented in tables for your reference.

Using ISO 10817-1 guidelines, you can calibrate measuring systems, and assess their accuracy so that you can get reproducible and accurate results when measuring the rotating shaft vibration on engines or motors. This contributes towards smooth functioning of these engines, mitigating risks to life and property.
