11、1 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 requirements shall not be considered as being in accordance
12、 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 IEC1020-6. In the preparation of detail specifications, the content of 1.5 of IEC1020-6 shall be tak
13、en into account. Pages 2 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 inserted in the position indicated. Ratings and characte
14、ristics 10Basic characteristics of the switch. The appropriate information for the tests in IEC1020-1 and1020-6 shall be provided in 1.2. Values shall be stated for the following ratings and characteristics which are mandatory: electrical endurance; electrical ratings; functional operation; operatin
15、g characteristics; robustness of actuator; 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 level endurance when a logic level rating is declared; l
16、ow level endurance when a low level rating is declared; type of seal when a panel seal or an enclosure seal is declared; resistance to soldering heat when the terminals are declared to be solderable; robustness of mounting bushing; robustness of mounting screws; robustness of terminations; solderabi
17、lity when the terminals are declared to be solderable; temperature rise when the switch is a heat-dissipating specimen. Identification of the detail specification 1 The International Electrotechnical Commission or the national standards organization under whose authority the detail specification is
18、drafted. 2 The IEC or national 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
19、 the switch 5 A short description of the type of sensitive 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.
