6.8 Choice of styles . The styles of resistors to be used in equipment should be so chosen that, when
mounted in the equipment, they will not be required to operate at a temperature in excess of their rating.
This should be applicable under the most severe combination of conditions with the equipment operating
as follows:
a. In the maximum specified ambient temperature.
b. Under conditions pr oducing maximum temperature rise in each resistor.
c. For a sufficient length of time to produce maximum temperature rise, or for the maximum specified
time.
d. With all enclosures in place.
e. With natural ventilation only (this should permit the us e of any special ventilating provisions
included as a standard part of the equipment).
f. At high altitude.
6.9 Soldering. When operated at full load, the maximum temperature may be 350C. The solder used
for connecting leads to the terminals should be chosen accordingly.
6.10 High frequency. Resistors should not be used in circuits where their ac performance is of critical
importance in the operation of such circuits.
6.11 Adjustments. Lugs should always be loosened completely before moving and should not be
except while the voltage is off, in order to protect the operator from dangerous voltages. When adjusted
to the position desired, the adjustable terminal should be tightened sufficiently to assure good electrical
contact.
6.12 Subject term (key word) listing.
Bracket assemblies
High frequency
Hotspot surface temperature
6.13 Changes from previous issue. Marginal notations are not used in this revision to identify changes
with respect to the previous issue due to the extensiveness of the changes.
