Connectors for electronic equipment. Tests and measurements - Fire hazard tests. Test 20a. Flammability, needle-flame1 Scope and object This part of IEC 60512, 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
