GB/T 7154.1-2003 in English

《GB/T 7154.1-2003直热式阶跃型正温度系数热敏电阻器 第1-1部分:限流用空白详细规范 评定水平EZ》由TC165（全国电子设备用阻容元件标准化技术委员会）归口，主管部门为工业和信息化部（电子）。
本标准是对GB/T 7154-1987＜直热式阶跃型正温度系数热敏电阻器第1-1部分：限流用空白详细规范评定水平E＞的修订，本标准与GB/T 7154-1987主要区别是补充了与作国限流使用时直热式阶跃型正温度系数热敏电阻器的有关性能参数和试验严酷度的要求，删除了原标准中不适用的性能参数要求并将质量评定水平由E改为EZ。

Scope

Blank Detail Specification Blank Detail Specification is a supplementary document to the General Specification, which includes requirements for the format, arrangement and at least the content of the Detail Specification. A detailed specification that does not comply with these requirements shall not be considered to be an IEC specification, nor shall it be called an IEC specification. The numbers in brackets on the first page indicate that the following corresponding content should be filled in the specified position: Identification of detailed specifications (1) The International Electrotechnical Commission or the national standardization organization authorized to draft this detailed specification. (2) The IEC or national standard number of the detailed specification, the date of issue, and other content required by the national system. (3) General specification number and version number of IEC or national standard. (4) Blank detail specification number of IEC or national standard. Identification of thermistor (5) A brief description of this type of thermistor. (6) Information on typical structures (where applicable). (7) Outline drawings marked with major dimensions that have an important impact on interchangeability and/or citing national or international documents on appearance. Alternatively, such outline drawings may also be given in the appendix to the detail specification. (8) Application or related application classification and/or assessment level. (9) Reference data of the most important characteristics for comparison between various types of thermistors.
