lEC 60068 -1, Appendix A, defines a method of specifying the climatic category by three groups of
numbers delimited by slash characters.
Example:
– 55 C
+ 85 C
56 days
1st group of numbers:
Absolute value of the lower category temperature T
2nd group of numbers:
Upper category temperature T
3rd group of numbers:
Number of days denoting the test duration for
10
The sizes of surface-mount components
The code differs depending on the standard which it is based on.
The American EIA standards require the length and width to be stated in hundredths of an inch, in
European standards and in the IEC draft standards, these dimensions are encoded in tenths of a
millimeter. The following table sumarizes the sizes:
