TESTS AND REQUIREMENTS

Essentially all tests are carried out in accordance with the

following specifications:

EN 60115-1, generic specification

EN 140400, sectional specification

EN 140401-801, detail specification

The testing also covers most of the requirements specified

by EIA/IS-703 and JIS-C-5202.

The tests are carried out in accordance with IEC 60068 (1)

and under standard atmospheric conditions according to

IEC 60068-1 (1)

, 5.3. Climatic category LCT/UCT/56 (rated

temperature range: Lower category temperature, upper

category temperature; damp heat, long term, 56 days) is

valid (LCT = - 55 °C/UCT = 125 °C).

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)

The requirements stated in the “Test Procedures and

Requirements” table are based on the required tests and

permitted limits of EN 140401-801 where applicable.
