IEC 62368-1 Clause 5.4.3 CTI PTI Tracking Flammability Test Chamber PLC Control
IEC 62368-1 Clause 5.4.3 CTI PTI Tracking Flammability Test Chamber PLC Control
Product Information:
The Tracking Flammability Test Chamber is designed and manufactured according to the standard requirements of IEC 62368-1:2018 clause 5.4.3, IEC 60335-1 clause 29.2, Annex N, IEC 60112, etc.
It is used for determination of the relative resistance to tracking performance that solid electrical insulating material under the action of an electric field, when the surface exposed to water containing impurities.
The working principle of the leakage tracking test (tracking index testing) is that the conducting liquid (0.1%NH 4 CL) of required volume in the required height (35mm) and required time (30s) drops with the voltage between the platinum electrodes (2mm × 5mm) on the surface of solid insulating material. Thus, the users evaluate the tracking resistance performance of solid insulating material surface under the combined influence of electric field and humid or contaminate medium. In a word, this device is used to measure the compare tracking index (CT1) and electrical resistance index (PT1).
