1 Scope
This International Standard specifies the maximum and minimum electrical resistance
of antistatic endless and open ended synchronous belts. This International Standard
provides guidelines to allow testing of synchronous belts to prove their static conductive
(dissipative) properties as well as a corresponding production control test method.
The application of this International Standard is limited to new belts intended to
be used in an explosive atmosphere or in situations where there is a fire risk. The
test is intended to ensure that the belt is sufficiently conductive to dissipate charges
of electricity which may form on it in service.
In the case of a production control test, the decision is left to national standards
or agreement between interested parties as to whether the test shall be carried out
on each belt in a batch or on only a percentage of belts in a batch.
For each proof test, the belt manufacturer shall determine which type of electrode
and conductive coating material shall be used.
