IEC 60938-2-2:1999 pdf download – Fixed inductors for electromagneticinterference suppression – Part 2-2: Blank detail specification – lnductors for which safety tests are required (only).
This blank detail specification forms the basis for a uniform procedure for a common mark. It implements the approval schedule for safety tests only in IEC 60938-2, requires a declaration of design for parameters relevant to safety tests and prescribes conformance tests to be conducted on every lot prior to its release and re-qualification tests depending on changes of the design.
In comparison with IEC 60938-2-1 which provides safety tests and performance tests, this specification is restricted to safety tests only.
The use of IEC 60938-2-1 may be more appropriate for components manufactured in mass production, whereas this specitication may be necessary in those cases where approval and requalification tests contribute considerably to the costs of the product.
A blank detail specification is a supplementary document to the sectional specification and contains requirements for style and layout and minimum content of detail specifications. In the preparation of detail specifications the content of 1 .4 of the sectional specification shall be taken into account.
The numbers between square brackets on the first page of the detail specification correspond to the following information which shall be inserted in the position indicated.
Identification of the detail specification and of the inductor
The first page of the detail specification should have the layout recommended on the next page of this blank detail specification.
(0) Manufacturer’s name.
(OAJ Manufacturer’s style designation.
(1) The “International Electrotechnical Commission” or the National Standards Organisation under whose authority the detail specification is 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 number of the IEC or national generic specification.
(4) The IEC number of the blank detail specification.
IdentIfication of the Inductor
(5) A short description of the inductor or range of inductors.
(6) Information on typical construction (when applicable).
1.5 Marking
The marking of the inductor shall be in accordance with the requirements of 1 .6 of IEC 60938-2.
The details of the marking of the component and package shall be given in full in the detail specification.
1.6 Ordering Information
Orders for inductors covered by this specification shall contain, in clear or in coded form, the following minimum information:
a) type designation;
b) rated inductance;
c) tolerance on rated inductance;
d) rated voltage;
e) rated current;
t) number and issue reference of the detail specification and style reference.
1.7 Additional information (not for inspection purposes)
1.8 Additional or increased seventies or requirements to those specified in the generic or sectional specification
NOTE — Additions or increased requirements should be specified only when essential.
