What is IEC 60068-2-78?

IEC 60068-2-78 is an international standard that specifies Test Cab: Damp heat, steady state, which determines the ability of components, equipment, and other articles to withstand the effects of warm humid atmosphere.

What humidity and temperature conditions are tested?

IEC 60068-2-78 covers damp heat testing with relative humidity typically at 93% ±3% and temperatures ranging from +40°C to +60°C, with specific conditions defined based on the intended application.

How does this apply to motorcycle keys?

IEC 60068-2-78 applies to motorcycle keys by ensuring electronic components, transponders, and key fobs can operate reliably in high humidity environments and tropical conditions.

What are the test procedures?

The test involves placing specimens in a controlled humidity chamber at specified temperature and humidity levels for defined durations, followed by conditioning and functional testing to verify performance after damp heat exposure.
