1.16.2 Test procedure

A capacitor of shall be charged by a suitable DC voltage source of in contact mode and in air mode. Then it shall be discharged through the gas analytical system (or its separate units) by connecting one terminal to the system’s ground chassis and the other through a resistance to the system’s surfaces that are normally accessible to the user. At least ten successive discharges shall be applied with a time interval between discharges of at least . A gas analytical system (or its separate units) not equipped with a grounding terminal (for which earthing is not provided) shall be placed on a grounded plane surface that projects beyond the gas analytical system (or its separate units) by at least on all sides. The associated grounded connection to the capacitor shall be as short as possible.
