9、 Page 1 Blank Detail Specification For In-line Switches A blank detail specification is a supplementary document to the Sectional Specification and contains requirements for style, layout and minimum content of detail specifications. Detail Specifications not complying with these requirements shall
10、not be considered as being in accordance with the certification system nor shall they be so described. In the preparation of detail specifications, the content of Subclause 2.6 of the Sectional Specification shall be taken into account. A detail specification shall cover a particular type of in-line
11、 switch construction and may include several styles for that type. It is preferable that all styles of a particular type of in-line switch construction be contained in a single detail specification wherever possible. Different construction types shall not be contained in the same detail specificatio
12、n. The detail specification shall state directly, or by reference to other documents, all information necessary to completely describe all interchangeability parameters for that type of in-line switch, including any styles, and to ensure conformance thereof with all requirements for quality assessme
