1.4 Information to be given in a detail specification
1.4.1 General
Detail specifications shall be derived from the 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.
The information given in 1 .4.2 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.
1.4.2 Outline drawings and dimensions
There shall be an illustration of the capacitors as an aid to easy recognition and for comparison of the capacitors 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.
The numerical values of the body shall be given as follows:
— general case: width, length and height;
— for cylindrical body: diameter and length.
The numerical values of the terminals shall be given as follows:
— for leaded terminals: diameter, length and spacing.
When the configuration is other than described above, the detail specification shall state such dimensional information as will adequately describe the capacitor.
1.4.3 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 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.
1.4.4 Rating and characteristics
1.4.4.1 General
The ratings and characteristics shall be given in accordance with the relevant subclauses of this sectional specification, including the items specified in 1 .4.4.2 to 1 .4.4.4.
1.4.4.2 Nominal capacitance range
See 2.2.1.
When products approved to the detail specification have different nominal capacitance ranges, the following statement should be added:
“The nominal capacitance range available in each voltage range is given in the register of approvals, available for example on the website www.iecq.org”.
1.4.4.3 Particular characteristics
Additional characteristics may be listed when they are considered necessary to specify adequately the component for design and application purposes.
1.4.4.4 SolderIng
The detail specification shall specify the test methods, seventies and requirements applicable for the solderability and the resistance to soldering heat tests.
1.4.5 Marking
The detail specification shall specify the content of the marking on the capacitor and on the packaging. Any deviations from 1 .6 shall be stated in the detail specification.
1.5 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60384-1:2016 and
the following apply.

1.5.1
capacitance
<electrolytic capacitor> capacitance of an equivalent circuit having capacitance and resistance in series measured with alternating current approximately sinusoidal waveform at a specified frequency
1.6 Marking
1.6.1 General
See IEC 60384-1 :2016, 2.4, with 1 .6.2, 1.6.3 and 1.6.4 of this document.
1.6.2 Information for marking
Information given in the marking is normally selected from the following list; the relative importance of each item is indicated by its position in the list:
a) polarity of the terminations;
b) nominal capacitance;
c) rated voltage (d.c. voltage may be indicated by the symbol: ____.(IEC 60417-5031-2002-10) or );
d) year and month (or, year and week) of manufacture;
e) manufacturer’s name and/or trade mark;
f) tolerance on nominal capacitance;
g) category temperature;
h) manufacturer’s type designation;
i) reference to the detail specification.IEC 60384-26 pdf download.
