    Abstract - (Show below) - (Hide below)

    Defines terms and methods of test for positive step-function temperature coefficient thermistors, insulated and non-insulated types, typically made from ferro-electric semi-conductor materials. Addresses standard terms, inspection procedures and methods of test used in detail specifications for Qualification Approval and Quality Assessment Systems for electronic components.
