What is IEC 60068-2-2?

IEC 60068-2-2 is an international standard that specifies Test B: Dry heat, which determines the ability of components, equipment, and other articles to be used, transported, or stored at high temperatures in dry conditions.

What temperature ranges are tested?

IEC 60068-2-2 covers dry heat test temperatures typically ranging from +16°C to +200°C, with specific temperature levels defined based on the intended application and environmental conditions.

How does this apply to motorcycle keys?

IEC 60068-2-2 applies to motorcycle keys by ensuring electronic components, transponders, and key fobs can operate reliably in hot weather conditions and high temperature environments such as engine compartments.

What are the test procedures?

The test involves placing specimens in a dry heat chamber at specified temperatures for defined durations, followed by conditioning and functional testing to verify performance after heat exposure.
