7 Information to be given in a detail specification
7.1 General
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.
The information given in 7.2 may, for convenience, be presented in tabular form.
The information in 7.2 to 7.5 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.
7.2 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.
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.
7.3 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 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.
7.4 Rating and characteristics
7.4.1 General
The ratings and characteristics shall be in accordance with the relevant clauses of this specification, together with 7.4.2 and 7.4.3.
7.4.2 Particular characteristics
Additional characteristics may be listed, when they are considered necessary to specify adequately the component for design and application purposes.
7.4.3 Soldering
The detail specification shall prescribe the test methods, seventies, and requirements
applicable for the solcierability and the resistance to solder heat test.
7.5 Marking
The detail specification shall specify the content of the marking on the capacitor and on the
package. Deviations from Clause 6 of this sectional specification shall be specifically stated.
8 Quality assessment procedures
8.1 Primary stage of manufacture
The primary stage of manufacture is the winding of the capacitor element or the equivalent operation.
8.2 Structurally similar components
Capacitors considered as being structurally similar are capacitors produced with similar processes and materials, though they may be of different case sizes and values.
8.3 Certified records of released lots
The information required in IEC 60384-1:2016, Q.1.5, shall be made available when prescribed in the detail specification and when requested by a purchaser. After the endurance test, the required parameters are the capacitance change, tangent of loss angle and insulation resistance.
8.4 Qualification approval procedures
8.4.1 General
The procedures for qualification approval testing i.s are given in IEC 60384-1 :20 16, Clause Q.2.
The schedule to be used for qualification approval testing on the basis of lot-by-lot and periodic
tests is given in 8.5. The procedure using a fixed sample size schedule is given in 8.4.2.
8.4.2 Qualification approval on the basis of the fixed sample size procedures
8.4.2.1 Sampling
The fixed sample size procedure is described in IEC 60384-1:2016, Q.2.4. The sample shall be representative of the range of capacitors for which approval is sought. This may be the whole or the part of the range given in the detail specification.IEC 60384-2 pdf download.
