5 Structure
Avibrator's structuredependsonthe type ofdrive (electric,pneumatic,hydraulic),parameters (frequencyand
centrifugal force) and the method of fixing tothe vibrating object. Examples of differentvibratorstructuresare
showninAnnex A.
6 Performance requirements
6.1 Frequency
Vibrators shall be classified according to their frequency, in accordance with Table 2,when subjected to the
loadtestaccordingto8.2.Thevibrator'sfrequencyshall complywith thedata as declared byits manufaoturer.

Designation Frequency
NF Below70Hz
HF 70Hzandabove
6.2 Centrifugalforce
A vibrator's prime movershall be sufficientto drive the device,without losing speed, such that the declared
centrifugal force ismaintainedcontinuouslyunderthe maximum loadofintendeduse.
6.3 Rating time
The rating time of a vibrator shall be continuous. For electric external vibrators, an intermittent duty (rating
class) specifiedaccordingto IEC60034-1:2004, 3.2and4.2, and agreedbetweenthe supplierand purchaser
ispermissible. Thedesignationofthesevibratorsshall correspondto IEC60745-1:2003,7.2.
6.4 Currentandpowerconsumption
The current and power consumption of the electric vibrators, when subjected to a load according to 8.2,
shouldcomplywithdata declaredbythe manufacturer.
6.5 Safety requirements
6.5.1 General
External vibrators shall be designedand theircomponentsselected,applied,mountedand adjustedtoprovide
safe operation. Inthe eventof afailure, the safety ofpersonnelshall be the prime consideration and damage
toequipmentandenvironmentminimized.Possible modesoffailureand intendedoperations and use shall be
considered.
It is recommended that technical principles and specifications according to ISO 12100-2 for the design of
vibratorsinrespectoftheir safety,be followedand used.

The vibrators shall be provided with means for connecting a protective conductor or an earth conductor. A
performance ofthese means shallcomply withtherequirements ofIEC60034-1:2004. 10.1.
6.5.2.6 Insulation resistance
The insulation resistance measured at 500V d.c. between the power circuit conductors and the protective
bondingcircuitshallnot belessthat 1MO.inaccordance with IEC60204-1:2000,19.3.
6.5.2.7 Withstandvoltagetest
The electric external vibrator shall withstand a test voltaye applied for a period of at least 1s between the
conductorsofallcircuits andtheprotective bondi.ngcircuit.Thetestvoltage shall
