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

12、 not complying with these requirements 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 IEC1020-3. In t

13、he preparation of detail specifications, the content of1.5 of IEC1020-3, 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

14、 information which shall be inserted in the position indicated. 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 national standards number of the d
