ENVIRONMENTAL REQUIREMENT
Following values are list of conditions where connector will be used. Connector manufacturer does not have to test connector according these conditions. However this information must be taken into account in connector design.
These requirements come from system requirements and will be replaced by a connector test specification in a second release of this document. 5.1 Environment specification for operation Climatic conditions:
-Temperature range -45…+85°C. -Relative humidity range
5…100% (ETS 300 019-1-4:1992, class 4.1). 0,26…29g/m3. 0,5°C/min.
70…106 kPa (ETS 300019-1-1:1991).
-Absolute humidity range
-Rate of temperature change -Air pressure range
Mechanical conditions:
Sinusoidal vibration: - Displacement
3,5mm peak between 5…9 Hz
- Acceleration 2m/s2 (~0.2g) - Frequency range 62…500 Hz - Sweeps
