EN 60068-2-67:1996/A1:2019

Environmental testing - Part 2-67: Tests - Test Cy: Damp heat, steady state, accelerated test primarily intended for components

Provides a standard test procedure for the purpose of evaluating the resistance of small electrotechnical products, primarily non-hermetically sealed components, to the deteriorative effect of damp heat. Is not intended to evaluate external effects such as corrosion and deformation.

Overview

EN 60068-2-67:1996/A1:2019 (equivalent to IEC 60068-2-67:1995/A1:2019) is a European amendment that specifies a damp heat, steady-state, accelerated test (Test Cy) primarily intended for electronic components. It forms part of the IEC 60068 environmental testing series and provides procedures to expose components to controlled humidity and temperature conditions to evaluate their resistance to moisture-related degradation and accelerated ageing.

Key topics and technical requirements

• Test purpose: Accelerated, steady-state damp heat exposure to reveal moisture-induced failures, corrosion, or loss of electrical/insulation properties in components.
• Test scope: Focused on discrete components and small assemblies (preferred application), with defined chamber and specimen handling procedures.
• Humidifying water specification (amendment A1):
  • Use distilled or deionised water for humidification.
  • Water resistivity: 2 000 Ω·m to 500 Ω·m, corresponding to a conductivity of 5 µS/cm to 20 µS/cm at +23 °C.
  • Clean all internal parts of the chamber before placing humidifying water (guidance in Clause B.3).
  • Notes: conductivity < 5 µS/cm can harm humidifier systems; conductivity > 20 µS/cm may cause limescale or mineral deposits on humidifier parts or specimens.
• Chamber and cleanliness: Emphasises cleaning of humidifier/storage tank and internal chamber parts to avoid contamination and ensure repeatable results.
• Parameters and profiles: The standard defines controlled combinations of temperature, relative humidity and exposure duration for accelerated steady-state testing (see full standard for specific profiles and acceptance criteria).

Applications

• Qualification and reliability screening of electronic components (semiconductors, capacitors, connectors, sensors).
• Accelerated ageing and humidity resistance testing during design validation, incoming inspection, and supplier qualification.
• Assessing susceptibility to corrosion, delamination, insulation breakdown, and moisture ingress under controlled accelerated conditions.
• Use in automotive, aerospace, industrial electronics, telecommunications, and consumer electronics product development and reliability labs.

Who should use this standard

• Test engineers and reliability specialists
• Environmental test laboratories and third‑party certification bodies
• Component manufacturers, QA and R&D teams
• Regulatory and standards compliance personnel

Related standards

• IEC/EN 60068 series (environmental testing methods) - consult the IEC 60068 catalogue for related damp heat and cyclic humidity tests.
