2 Technical data
2.1 Units and symbols
Units, graphical symbols and letter symbols should, whenever possible, be taken from the following
publications:
– EN 60027-1;
– IEC 60050;
– IEC 60617;
– ISO 80000-1.
When further items are required they shall be derived in accordance with the principles of the publications
listed above.
2.2 Terms and definitions
For the purposes of this document, the following terms and definitions apply, in alphabetical order of the
English terms:
NOTE The sequential numbering of terms and definations is not suitable for referencing.
2.2.1
category dissipation
fraction of the rated dissipation exactly defined in the detail specification, applicable at the upper category
temperature, taking account of the derating curve prescribed in the detail specification
NOTE 1 For resistors the category dissipation is zero, where the upper category temperature is the maximum element
temperature.
NOTE 2 Related terminology: rated dissipation, upper category temperature, derating curve.
2.2.2
category temperature range
range of ambient temperatures for which the resistor has been designed to operate continuously; this is
given by the lower and upper category temperature
NOTE Related terminology: lower category temperature, upper category temperature.
2.2.3
critical resistance
resistance value at which the rated voltage is equal to the limiting element voltage
NOTE 1 At an ambient temperature of 70 °C, the maximum voltage which may be applied across the terminations of a
resistor is either the calculated rated voltage, if the resistance is less than the critical resistance, or the limiting element
voltage, if the resistance is equal to or greater than the critical resistance. At temperatures other than 70 °C, it is
important that account be taken of the derating curve and of the limiting element voltage in the calculation of any voltage
to be applied.
NOTE 2 Related terminology: Rated voltage, limiting element voltage.
2.2.4
derating curve
curve which shows the maximum allowable dissipation at ambient temperatures between the upper
and lower category temperature
NOTE 1 In the range between lower category temperature and rated temperature it shows the rated dissipation, and
between rated temperature and maximum element temperature it shows a linear slope down to zero dissipation at the
maximum element temperature. The slope depends on the thermal properties of the resistor, i.e. its capability to abduct
the dissipation to the environment.
NOTE 2 Related terminology: rated dissipation, rated temperature, maximum element temperature.

2.2.5
failure rate level
accumulated number of non-conforming units under specified operating conditions and specified
accumulation time, evaluated for a given confidence level
NOTE Related terminology: non-conformance, non-conforming unit.
2.2.6
grade
term indicating additional general characteristics concerning the intended application, for example,
long-life applications
NOTE 1 The term "grade" may be used only in combination with one or more words (for example, long-life grade) and
not with a single letter or number.
NOTE 2 Related terminology: stability class.
2.2.7
heat-sink resistor
resistor type designed for mounting on a separate heat-sink
NOTE Related terminology: rated dissipation

insulated resistor
resistor which fulfils the voltage proof and insul
