Evaluation criteria:
The test is considered passed when,
- the control unit shows definite signs of visible damage and theunit would be designated as being defective
- there are no obvious defects visible to the control unit or itscomponents, and the functions are fully assured.
4. Type of protection
Test without attachment of dummy harness connector underconsideration of the permissible installation positions inaccordance with the offer drawing.
To be tested for new connection systems.
Standard: DIN 40 050 sh. 9 (May 93).

Ventilation via pressure compensation element
Degree of protection: IP 54 K
Test using revolving pipe
Test duration: 10 min.Mains pressure: 400 kPa
Water temperature: room temperature
5. Notes on connectors
The connections developed by RB are tested and approved by thedevelopment departments responsible. In addition, evaluations ofthe connection systems are conducted within the scope of equipmentand system testing.
For connectors from outside sources (connector is prescribed by thecustomer --> no RB-connector), the approval testing must be
conducted by the supplier of theconnectors and documented within the scope of evidential testing(Test Reports). In addition, these connectors are subjected to areduced evaluation (e.g. abrasion, contact, sealing....) withinthe scope of equipment testing.
As a matter of principle, the connector must comply with thecontrol unit specification.
