Testing vehicles’ electrical and electronic equipment
Testing wiring harnesses, connectors, push connections (crimps) and other components
The range of tests of wires and wiring harnesses
- measurement of the active resistance of conductors
- studies on the influence of environmental factors on wiring insulation (ageing tests)
- measurements of the electrical parameters of wiring insulation (electrical resistance and durability)
- tests of mechanical parameters (impact, stretching, winding)
- tests of resistance to chemical agents
- other tests, within our technical capabilities.

The range of tests of connectors and crimp connections
- measurement of voltage drops with determination of resistance: connections, crimp connections, connector material
- measurement of the temperature increase at a joint as a function of current load
- studies on the influence of environmental factors on joint parameters (e.g. high temperature, salt spray, vibrations, thermal shocks)
- cyclic tests
- tests of electrical durability and measurement of connectors’ insulation resistance
- tightness testing of hermetic joints and sealed cable connections
- other tests, within our technical capabilities.

Testing sensors and transducers
BOSMAL performs various types of electronic and electrotechnical tests of sensors and transducers. These include:
- measurements of electrical parameters and characteristics,
- testing of resistance to environmental conditions.
Measurements of electrical parameters and characteristics of sensors and transducers
BOSMAL performs measurements of electrical parameters and sensor characteristics:
- ABS,
- shaft position,
- oxygen content in the exhaust (lambda sensor),
- relative pressure of exhaust gases,
- LPG gas level,
- temperature (mirrors, air-conditioning system and others),
- distance ((for parking and collision avoidance),
- position of the angle of heel of the vehicle,
- others in terms of technical capabilities.

Exterior and interior vehicle lighting systems
Systems of external and internal lighting of vehicles are subjected to tests such as:
- durability and functional tests (including vibration tests – including vibration tests of electronic systems embedded in lighting fixtures).
- tests of resistance to environmental conditions (e.g. tests of resistance to dust and water),
- optical tests,
- material tests.
