德国PTL灼热丝测试仪,符合标准IEC60695-2-10:2000、IEC60695-2-13：2000（灼热丝/专线基本试验方法，灼热丝试验装置和通过试验程序）、IEC829， DIN695和VDE0471等.
它是将规定材质和形状的电热丝用大电流加热至试验温度(550℃-960℃)1min 后，以规定压力（1.0N）垂直灼烫试品30s,视试品和铺垫物是否起燃或持燃时间来测定电工电子设备成品的着火危险;测定固体绝缘材料及其它固体可燃材料的起燃性，起燃温度（GWIT）、可燃性和可燃性指数（GWFI）
PTL Glow Wire Test Apparatus
The test procedure is used to examine the fire resisting properties of products if, during the application or in the case of a fault, heated or glowing parts could be considered as a short-time ignition source. Loose connections or bad contacts cause
punctually high temperatures on electrical articles, their components and their parts. Attention should also be paid to the fire risk in connection with textile seat coverings, table-cloths, or curtains, e.g. after coming into contact with a lighted cigarette.
For this reason, prototypes of all articles which could be a source of danger if they con-tact with ignition sources should be subjected to the Glow-wire Test.
