Environmental Testing IEC 60529 2 30 2005

IEC 60068-2-30 is the definitive standard for evaluating how components and equipment withstand high humidity combined with cyclic temperature changes. This test simulates the “breathing effect” where temperature fluctuations cause air pressure changes inside a device, pumping moisture in and leading to condensation. It is critical for ensuring product reliability in tropical or uncontrolled outdoor environments.

• Identifies Insulation Failures: Detects electrical leakage caused by moisture absorption.
• Evaluates Physical Degradation: Checks for swelling of plastics, corrosion of metals, and gasket failures.
• Verifies Seal Integrity: Ensures seals remain effective under thermal stress and condensation.
