Blank detail specification
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 use of IEC 60939-2-2 may be more appropriate for components where approval and requalification tests contribute considerably to the cost of the product, whereas the employment of this specification may be necessary for components manufactured in mass production. This specification offers the assessment levels D and DZ (Zero defect).
Identification of the detail specification and of the component
The first page of the detail specification should have the layout recommended on the next page of this blank detail specification. The numbers between square brackets correspond to the following information which shall be inserted at the position indicated:
 The name of the National Standards Organization under whose authority the detail specification is published and, if applicable, the organization from which the detail specification is available.
 The IECQ symbol and the number allotted to the detail specification by the IECQ General Secretariat.
 The number and issue number of the IECQ generic or sectional specification as relevant; also national reference if different.
 If different from the IECQ number, the national number of the detail specification, date of issue and any further information required by the national system, together with any amendment numbers.
 A brief description of the component or range of components.
 Information on typical construction (when applicable).
For  and  the text to be given in the detail specification should be suitable for an entry in the IECQ Register of Approvals.
 Outline drawing with main dimensions which are of importance for interchangeability and/or reference to the appropriate national or international documents for outlines. Alternatively the drawing may be given in an annex to the detail specification, but  should always contain an illustration of the general outer appearance of the component.
 The level(s) of quality assessment covered by the detail specification, as appropriate.
 Reference data giving information on the most important properties of the component which allow comparison between the various component types intended for the same or similar applications.
