TESTS AND REQUIREMENTS

All executed tests are carried out in accordance with the

following specifications:

EN 60115-1, generic specification

EN 60115-8, sectional specification

EN 140401-802, detail specification

IEC 60068-2-xx, test methods

The parameters stated in the Test Procedures and

Requirements table are based on the required tests

and permitted limits of EN 140401-802. The table presents

only the most important tests, for the full test schedule refer

to the documents listed above. However, some additional

tests and a number of improvements against those

minimum requirements have been included.

The testing also covers most of the requirements specified

by EIA/IS-703 and JIS-C-5201-1.

The tests are carried out under standard atmospheric

conditions in accordance with IEC 60068-1, 4.3, whereupon

the following values are applied:

Temperature: 15 °C to 35 °C

Relative humidity: 25 % to 75 %

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

A climatic category LCT / UCT / 56 is applied, defined by the

lower category temperature (LCT), the upper category

temperature (UCT), and the duration of exposure in the

damp heat, steady state test (56 days). The components

are mounted for testing on boards in accordance with

EN 60115-8, 2.4.2 unless otherwise specified.
