What duration is specified for each vertical impact in the shock test?

The specified duration for each vertical impact in the shock test is 16-20 milliseconds. This range is set to simulate real-world conditions in which equipment on a vessel might experience sudden shocks or impacts, such as from waves or rough handling.

A duration in this range ensures that the test mimics the energy and forces that equipment could encounter while operating in a marine environment. The selected duration is crucial for accurately assessing the resilience and reliability of electrical installations and components under stress, helping to ensure they can withstand these conditions without failure.

Understanding this parameter helps manufacturers and technicians design and select electrical components that maintain functionality and safety in challenging marine applications.
