当详细规范要求时，IEC 60512-20-3:2010用于测试技术委员会48范围内的连接器。当详细规范中有规定时，也可用于类似装置。本标准的目的是详细说明一种标准试验方法，以确定连接器在特定条件下暴露于电热丝试验时的易燃性。为了通过模拟技术评估单个电子元件的火灾危险或燃烧，电热丝试验短期模拟了热源或火源（例如发光元件或过载部件）可能产生的热应力。

IEC 60512-20-3:2010 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 test method to determine the flammability of a connector when exposed to a glow-wire test under specified conditions. The glow-wire test simulates thermal stresses which may be produced by such sources of heat or ignition as, for example, glowing elements or overloaded components, for short periods, in order to assess by a simulation technique the fire hazard or burning of a single electronic component.
