IEC 60512-20-1:2010 when required by the detail specification, is used for testing connectors within the scope of technical committee 48. It may also be used for similar devices when specified in a detail specification. The object of this standard is to detail a standard method to determine the flammability of a connector when exposed to a needle-flame under specified conditions. The needle-flame test is intended to simulate the effect of small flames which may result from fault conditions within the equipment, i.e. the intensity of the ignition source used is of a similar order to that of an accidentally overheated or burning single electronic component.
