GB/T 10715-2021Belt drives - V-ribbed belts, joined V-belts and V-belts including wide section belts and hexagonal belts - Electrical conductivity of antistatic belts: Characteristics and methods of test (English PDF)

1 Scope

This standard specifies the maximum resistance and

Its test method.

This standard is only applicable to new belts intended to be used in occasions where there is a risk of explosion or fire. The test is set up to ensure that the belt has enough

To discharge the electric charge generated during operation.

In the product control test, it is determined by the national standard or the agreement of relevant parties whether to test each strip of a batch of belts or

A certain percentage of a batch of belts is selected for testing.

Note. For the product acceptance test, the belt manufacturer should determine which electrode and conductive coating material need to be used.
