标准摘要
Applies to directly heated positive temperature coefficient thermistors, insulated or non-insulated, having a resistance temperature characteristic which approximates to a step-function. Typically they are made of ferro-electric semi-conductive materials. Specifies the conditions for approval, acceptance and continuous quality control. Defines the terminology for the thermistors covered by this standard, and defines the methods of test.
