IEC 60393-6-2015 pdf download.Potentiometers for use in electronic equipment – Part 6: Sectional specification – Surface mount preset potentiometers.
This part of IEC 60393 applies to surface mount preset potentiometers for use in electronic equipment.
This part of IEC 60393 prescribes preferred ratings and characteristics and selects from
IEC 60393-1 , the appropriate quality assessment procedures, tests and measuring methods, and it gives general performance requirements for this type of potentiometers.
This standard gives the minimum performance requirements and test severities.

1.3 Information to be given in a detail specification
1.3.1 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 a subclause of the detail specification and indicated in the test schedules, for example by an asterisk.
The information given in 1 .3.2 and 1 .3.4 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.
1.3.2 Outline drawing and dimensions
The detail specification shall incorporate an illustration of the surface mount preset potentiometer as aid to easy recognition and for comparison of the surface mount potentiometer with others.
Dimensions and their associated tolerances, which affect interchangeability and mounting, shall be given in the detail specification. All dimensions shall be stated in millimetres.
Normally the numerical values shall be given for the length, width and thickness of the body.
Where space is insufficient to show the detail dimensions required for inspection purposes, such dimensions shall appear on the drawing forming an annex to the detail specification.
Recommended land patterns shall be given in the detail specification.
When the outline drawing is other than described above, the detail specification shall state such dimensional information as will adequately describe the surface mount potentiometer.IEC 60393-6 pdf download.
