1、 Continuous spark ignition: maximum permissible no load voltage: 10 kV （peak）; maximum permissible current: 0,7 mA （peak）. If the no load voltage exceeds 10 kV: the discharge shall not exceed: 45 4As; with a maximum permissible current: Pulse repetition ignition: a maximum admissible discharge of 45

2、 4As per pulse and a maximum pulse duration of 0,1 ms measured from the beginning of the pulse until decreasing to 10 % of the peak value; maximum pulse repetition frequency: 25 Hz.NOTE 1 Detailed information is given in IEC 479-1 and IEC 479-2.NOTE 2 For normal and abnormal operation: the limits al
