1.4 Information to be given in a detail specification
Detail specifications shall be derived from the relevant blank detail specification.
Detail specifications shall not specify requirements inferior to those of the generic, sectional or blank detail specification. When more severe requirements are included, they shall be listed in 1 .9 of the detail specification and indicated in the test schedules, for example, by an asterisk.
NOTE The information given in 1 .4.1 may, for convenience, be presented in tabular form.
The following information shall be given in each detail specification and the values quoted shall preferably be selected from those given in the appropriate clause of this sectional specification.
1.4.1 Outline drawing and dimensions
There shall be an illustration of the capacitor as an aid to easy recognition and for comparison of the capacitor with others. Dimensions and their associated tolerances, which affect interchangeability and mounting, shall be given in the detail specification. All dimensions shall preferably be stated in millimetres; however, when the original dimensions are given in inches, the converted metric dimensions in millimetres shall be added.
Normally, the numerical values shall be given for the length of the body, the width and height of the body and the wire spacing, or for cylindrical types, the body diameter, and the length and diameter of the terminations. When necessary, for example, when a number of items (capacitance values/voltage ranges) are covered by a detail specification, the dimensions and their associated tolerances shall be placed in a table below the drawing.
When the configuration is other than described above, the detail specification shall state such dimensional information as will adequately describe the capacitor. When the capacitor is not designed for use on printed boards, this shall be clearly stated in the detail specification. 1 .
4.2 Mounting The detail specification shall specify the method of mounting to be applied for normal use and for the application of the vibration and the bump or shock tests. The capacitors shall be mounted by their normal means. The design of the capacitor may be such that special mounting fixtures are required in its use. In this case, the detail specification shall describe the mounting fixtures and they shall be used in the application of the vibration and bump or shock tests.
1.4.3 Ratings and characteristics
The ratings and characteristics shall be in accordance with the relevant clauses of this specification, together with the following.
1.4.3.1 Rated capacitance range
See 2.2.1 .
NOTE When products approved to the detail specification have different ranges, the following statement should be added: “The range of values available in each voltage range is given in IECQ 001 005”.
1.4.3.2 Particular characteristics
Additional characteristics may be listed when they are considered necessary to specify adequately the component for design and application purposes.
