IEC 60393-5-2015 pdf download.Potentiometers for use in electronic equipment – Part 5: Sectional specification – Single-turn rotary low-power wirewound and non-wirewound potentiometers.
This part of IEC 60393 applies to single-turn rotary low-power wirewound and non-wirewound potentiometers, with a rated dissipation less than to 1 0 W. These potentiometers are primarily intended for use in electronic equipment.
This part of IEC 60393 prescribes preferred ratings and characteristics and selects from
IEC 60393-1 , appropriate quality assessment procedures, tests and measuring methods. It provides general performance requirements for this type of potentiometer.
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 .3.3 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 potentiometer being specified. Where space is insufficient to show the detail dimensions required for inspection purposes, such dimensions shall appear on a drawing forming an annex to the detail specification, as shown in Figure 1 .
The drawing shall give the following details:
– the dimensions of the shaft and bush. These may be given either on the outline drawing or by reference to IEC 6091 5;
– any locating devices;
– the total mechanical travel;
– the effective electrical travel;
– the angle of ineffective mechanical travel;
– the switch angle (if applicable);
– the dimensions of the switch, if fitted, and the location of terminations;
– the dimensions which shall be measured in accordance with IEC 60393-1 :2008, 4.4.2;
– any other dimensional information which will adequately describe the potentiometer.
All dimensions shall preferably be stated in millimetres, however, when the original dimensions are given in inches, the converted metric dimensions in millimetres shall be added.
When the potentiometer is not designed for use on printed boards, this shall be clearly indicated in the detail specification.IEC 60393-5 pdf download.
