Vishay BCcomponents
High Ohmic/High Voltage Resistors
TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with the
schedule
of
“IEC publication
LCT/UCT/56 (rated temperature range: Lower Category
Temperature, Upper Category Temperature; damp heat,
long term, 56 days). The testing also covers the
requirements specified by EIA and EIAJ.
60115-1”,
category
The tests are carried out in accordance with IEC publication
60068-2, “Recommended basic climatic and mechanical
robustness testing procedure for electronic components”
and under standard atmospheric conditions according to
“IEC 60068-1”, subclause 5.3.
In the Test Procedures and Requirements table the tests and
requirements are listed with reference to the relevant
clauses of “IEC publications 60115-1 and 60068-2”; a short
description of the test procedure is also given. In some
instances deviations from the IEC recommendations were
necessary for our method of specifying.
All soldering tests are performed with mildly activated flux.
