Blank detail specification
A blank detail specification is a supplementary document to a detail specification and contains requirements for the format, arrangement and minimum content of a detail specification. A detail specification that does not comply with these requirements is not considered to be a standard that meets the requirements of the electronic component quality assessment system. The content of clause 1.4 of the detail specification should be considered when formulating the detail specification. The following corresponding information should be filled in the position marked with a number in brackets on the first page: Identification of the detail specification:
[1] Organization authorized to draft this detail specification: IEC or national standards body. [2] IEC or national standard detail specification number, date of publication and any further information as required by the national system. [3] IEC or national standard general specification number and year number. [4] IEC or national standard blank detail specification number. Identification of capacitors:
[5] Brief description of capacitor type.
C6] Brief description of typical construction.
NOTE: When the capacitor is not designed for use in printed circuit boards, this should be clearly stated at this point in the detail specification. [7] Outline drawing with the main dimensions important for interchangeability and/or reference to national or international outline drawings. Alternatively, such drawings may be given in an annex to the detail specification. (8). Application or application group and/or assessment level involved. Note: One or more assessment levels used in the detailed specification shall be selected from clause 3.5.4 of the sub-specification. This means that as long as the division of the test groups remains unchanged, several assessment levels can share one detailed specification. [9] Reference data of the most important characteristics to facilitate comparison between various types of capacitors. Approved by the Ministry of Electronics Industry of the People's Republic of China on October 30, 1987 and implemented on February 1, 1989
