本标准适用于电子设备用所有类型电阻性电位器,包括螺杆驱动型、预调型、多圈电位器等。 本标准规定了电子元器件质量评定体系和鉴定批准用分规范和详细规范中所采用的标准术语、检验程序和试验方法。 本标准规定试验方法主要按广泛使用的带控制轴的单圈旋转式电位器缩写的。对于其他型式的 电位器: --旋转角可能是多圈的; --所指的控制轴应也适用于其他驱动机构的; --旋转角应理解为表示驱动机构的机械行程的。
本标准适用于电子设备用线绕和非线绕的螺杆驱动和旋转预调电位器。这类电位器主要用在很少需要调节的电路中作微调用。
空白详细规范 空白详细规范是分规范的一种补充性文件,并包括了详细规范的格式、编排和少内容的要求。不遵守这些要求的详细规范不应认为是符合电子元器件质量评定体系要求的规范,也不能按本规范进行编写。
本规范适用于WIW141型螺杆驱动预调电位器,它是按照GB/T 15300-1994《电子设备用电位器 第二部分:空白详细规范 螺杆驱动和旋转预调电位器 评审水平E》(idt IEC60393-2-1-1989)制定的,符合GB/T 15298-1994《电子设备用电位器 第一部分:总规范》(idt IEC 60393-1-1989)和GB/7 15299-1994《电子设备用电位器 第二部分:分规范 螺杆驱动和旋转预调电位器》(idt IEC 60393-2-1-1989)的要求。
Contains requirements for style and layout and minimum content of detail specifications. Specifies requirements for dimensions, ratings, characteristics, marking and ordering informations. Describes the inspection requirements including sampling, periodicity, severities and requirements.
This part of IEC 60393 applies to lead-screw actuated and rotary preset potentiometers, wirewound and non-wirewound for use in electronic equipment. These potentiometers are primarily intended for use in circuits for trimming purposes which require infrequent adjustments. This part of IEC 60393 prescribes preferred ratings and characteristics and selects from IEC 60393-1 the appropriate quality assessment procedures, tests and measuring methods. It provides general performance requirements for this type of potentiometer. This standard gives the minimum performance requirements and test severities.
