3 Terms and Definitions
For the purposes of this part of GB/T 12703, the following terms and definitions apply.
3.1
electric charge
charge carried by the sample after rubbing with the standard cloth for a certain period of time
4 Principle
A friction device is used to simulate the circumstance that the sample carries electric charge due to friction, and then the sample is put into a Faraday cylinder for measurement of the electric charge.
5 Apparatus
