No grease or similar compound shall be used in or on the test item. After the sample is purged of air, the 50 Hz voltage shall
23、be slowly increase until the detector operated at a sensitivity of five picocoulombs level or less. The latter Voltage value is being the Corona level of the connector under test. A Corona detector may be use instead of the test set up describes in Figure 1. 6 Requirements Corona level shall be less
