TESTS PROCEDURES AND REQUIREMENTS

All tests are carried out in accordance with the following

specifications:

• IEC 60115-1, generic specification (includes tests)

The test and requirements table contains only the most

important tests. For the full test schedule refer to the

documents listed above.

The tests are carried out with reference to IEC 60115-1, in

accordance with IEC 60068-2-xx test method and under

standard atmospheric conditions in accordance with

IEC 60068-1, 5.3.

A climatic category 55 / 155 / 56 is applied, defined by the

lower category temperature (LCT = -55 °C), the upper

category temperature (UCT = 155 °C), and the duration

of exposure in the damp heat, steady state test (56 days).

VR25, VR37, VR68

Vishay BCcomponents

Unless otherwise specified the following values apply:

• Temperature: 15 °C to 35 °C

• Relative humidity: 45 % to 75 %

• Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).

For performing some of the tests, the components are

mounted on a test board in accordance with IEC 60115-1,

4.31.

In test procedures and requirements table, only the tests

and requirements are listed with reference to the relevant

clauses of IEC 60115-1 and IEC 60068-2-xx test methods.

A short description of the test procedure is also given.
