11、01:1992 BSI 10-1999 1 Section 1. Blank detail specification Introduction A blank detail specification is a supplementary document to the sectional specification and contains requirements for style, lay-out and minimum content of detail specifications. Detail specifications not complying with these r

12、equirements shall not be considered as being in accordance with the IECQ System nor shall they so be described. The complete requirements for the switches described herein shall correspond to this detail specification and the current issues of IEC1020-1 and IEC1020-2. In the preparation of detail sp

13、ecifications, the content of1.5 of IEC1020-2 shall be taken into account. Pages2 through6 provide the framework for a detail specification which is completed by inserting the necessary information. The numbers between brackets on the first page correspond to the following information which shall be

14、inserted in the position indicated. contact resistance; electrical endurance; electrical ratings; voltage proof. Values shall be stated in1.2 for the following characteristics when the following conditions exist (mandatory if applicable): low air pressure when an altitude rating is declared; logic l

15、evel endurance when a logic level rating is declared; low level endurance when a low level rating is declared; end stops when end stops are declared; type of panel seal when a panel seal is declared; robustness of actuator; robustness of terminations; solderability when the terminals are declared to

16、 be solderable; resistance to soldering heat when the terminals are declared to be solderable. Identification of the detail specification 1 The International Electrotechnical Commission or the national standards organization under whose authority the detail specification is drafted. 2 The IEC or nat

17、ional standards number of the detail specification, date of issue and any further information required by the national system. 3 The number and issue of the IEC or national generic specification. 4 The number and issue of the IEC blank detail specification. Identification of the switch 5 A short des

18、cription of the type of rotary switch which shall include as a minimum the information needed for listing on the qualified products list. 6 A circuit diagram or short description of the electrical circuit(s). 7 Dimensions important for interchangeability. When space permits, the drawing may also inc

19、lude detailed dimensions. The drawing shall comply with1.5.1 of IEC1020-2. 8 Information on the typical construction (when applicable). 9 Assessment level. Ratings and characteristics 10 Basic characteristics of the switch. The appropriate information for the tests in IEC1020-1 andIEC1020-2 shall be
