本標準適用于電子設備用所有類型電阻性電位器,包括螺桿驅動型、預調型、多圈電位器等。 本標準規(guī)定了電子元器件質量評定體系和鑒定批準用分規(guī)范和詳細規(guī)范中所采用的標準術語、檢驗程序和試驗方法。 本標準規(guī)定試驗方法主要按廣泛使用的帶控制軸的單圈旋轉式電位器縮寫的。對于其他型式的 電位器: --旋轉角可能是多圈的; --所指的控制軸應也適用于其他驅動機構的; --旋轉角應理解為表示驅動機構的機械行程的。
本標準適用于電子設備用線繞和非線繞的螺桿驅動和旋轉預調電位器。這類電位器主要用在很少需要調節(jié)的電路中作微調用。
空白詳細規(guī)范 空白詳細規(guī)范是分規(guī)范的一種補充性文件,并包括了詳細規(guī)范的格式、編排和少內容的要求。不遵守這些要求的詳細規(guī)范不應認為是符合電子元器件質量評定體系要求的規(guī)范,也不能按本規(guī)范進行編寫。
本規(guī)范適用于WIW141型螺桿驅動預調電位器,它是按照GB/T 15300-1994《電子設備用電位器 第二部分:空白詳細規(guī)范 螺桿驅動和旋轉預調電位器 評審水平E》(idt IEC60393-2-1-1989)制定的,符合GB/T 15298-1994《電子設備用電位器 第一部分:總規(guī)范》(idt IEC 60393-1-1989)和GB/7 15299-1994《電子設備用電位器 第二部分:分規(guī)范 螺桿驅動和旋轉預調電位器》(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.
