BS ISO 10816-3:2009+A1:2017

This part of ISO10816 gives criteria for assessing vibration levels when measurements are made in situ. The criteria specified apply to machine sets having a power above 15kW and operating speeds between 120r/min and 15000r/min. The machine sets covered by this part of ISO10816 include: steam turbines and generators with outputs less than or equal to 40MW; steam turbines and generators with outputs greater than 40MW and speeds other than 1500r/min, 1800r/min, 3 000r/min or 3600r/min (although generators seldom fall into this category); rotary compressors; industrial gas turbines with outputs less than or equal to 3MW; electrical motors of any type; blowers or fans. NOTE However, the vibration criteria presented in this part of ISO10816 are generally only applicable to fans with power ratings greater than 300kW or fans which are not flexibly supported. As and when circumstances permit, recommendations for other types of fans, including those with lightweight sheet metal construction, will be prepared. Until such time, classifications can be agreed between the manufacturer and the customer, using results of previous operational experience, see also ISO14694 . The following are excluded from this part of ISO10816 : steam turbines and/or generators with outputs greater than 40MW and speeds of 1500r/min, 1800r/min, 3000r/min or 3600r/min (see ISO20816-2 ); gas turbine sets with outputs greater than 3MW (see ISO10816-4 and ISO20816-2 ); machine sets in hydraulic power generating and pumping plants (see ISO10816-5 ); machines coupled to reciprocating machines (see ISO10816-6 ); rotodynamic pumps including integrated electric motors, i.e. where the impeller is mounted directly on the motor shaft or is rigidly attached to it (see ISO10816-7 ); rotary positive displacement compressors (e. g. screw compressors); reciprocating compressors (see ISO10816-8 ); reciprocating pumps; submerged motor-pumps; wind turbines. The criteria of this part of ISO10816 apply to in situ broad-band vibration measurements taken on the bearings, bearing pedestals, or housing of machines under steady-state operating conditions within the nominal operating speed range. They relate to both acceptance testing and operational monitoring. The evaluation criteria of this part of ISO10816 are designed to apply to both continuous and non-continuous monitoring situations. This part of ISO10816 encompasses machines which may have gears or rolling element bearings, but does not address the diagnostic evaluation of the condition of those gears or bearings. The criteria are applicable only for the vibration produced by the machine set itself and not for vibration which is transmitted to the machine set from external sources.
