1.3.6.1 General
The ratings and characteristics shall be in accordance with the relevant clauses of this
specification together with the following.
1.3.6.2 Nominal total resistance range
See IEC 60393-1:2008, 2.3.2.
When products approved according to the detail specification have different ranges, the following statement should be added:
The range of values available in each style is given in the register of approvals, available for example on the website http://www.iecg.org/.
The qualified products list QPL style is given in the register of approvals, available, for example. on the website as stated above.
1.3.6.3 Particular characteristics
Additional characteristics may be listed, when they are considered necessary to specify adequately the component for design and application purposes.
1.3.6.4 Soldering
The detail specification shall prescribe the test methods, severity and requirements applicable for the solderability and the resistance to soldering heat tests.
1.3.7 Marking
The detail specification shall specify the content of the marking on the surface mount preset potentiometer and on the package. Deviation from 1 .4 shall be specifically stated.
Surface mount preset potentiometers are generally not marked on the body. If some marking can be applied, the surface mount preset potentiometer shall be clearly marked with the nominal total resistance and many of the remaining items in IEC 60393-1:2008, 2.4.
All items shall be marked on the package.
1.3.8 Ordering information
The detail specification shall indicate that the Following information, in clear or in coded form. is required when ordering:
a) nominal total resistance and tolerance on nominal total resistanc:
b) number and issue reference of the detail specification and style reference.IEC 60393-6 pdf download.
