Photography — Synchronizers, ignition circuits and connectors for cameras and photoflash units — Electrical characteristics and test methods

Requirements for synchronizer and ignition circuit are concerned with polarities of terminals, voltage across and current through terminals, for ignition circuit with operation, for synchronizer with dynamic characteristics and leakage current, and for cables with resistance, capacitance, and insulation resistance. Test methods relate to ignition circuit operation, synchronizer dynamic characteristics, and synchronizer leakage current.
