With climates becoming ever more extreme, environmental testing in the harshest of conditions is critical to a product’s success says Raymarine. Changes in climate extremes and their impacts


Vibration test


on the natural physical environment means that technology needs to be more durable than ever. The ability of a product to withstand the environment within which it has to operate, is critical to its success and the reason Raymarine goes beyond industry standards to test its marine products.


Raymarine’s testing centre in the UK is at the forefront of the industry. The facility provides a comprehensive range of accredited marine environmental testing, from hard drops, prolonged vibration, extreme temperatures, wireless emissions, relentless rain and spray, full submersion, and the simulation of months at sea inside a salt mist chamber.

Vibration is the hidden enemy for both electronics and mechanical structures. Constant shaking across a range of frequencies can create loose connections, fatigue wires, damage solder joints and result in equipment failure.


Vibration testing at Raymarine’s environmental test centre goes well beyond standard tests. In the shaker room, vertical and horizontal shakers perform swept sine and dwell tests, subjecting items to a vibration sine tone across a broad frequency range. Where a resonance is found during the sweep, testers dwell on that frequency for two hours, then check for fatigue damage. The standard test is 5Hz-100Hz, but Raymarine pushes that to 600Hz, as well as performing shock and random vibration tests simulating and surpassing real-life vibration data from customers’ boats.
