Overview

EN 60068-2-67:1996, titled Environmental Testing - Part 2: Tests - Test Cy: Damp Heat, Steady State, Accelerated Test Primarily Intended for Components, is an essential standard developed by the CLC (European Committee for Electrotechnical Standardization). This standard establishes a testing procedure designed to evaluate the resistance of small electrotechnical components-especially non-hermetically sealed parts-to the harmful effects of damp heat under accelerated conditions. It facilitates reliable assessment of component durability within controlled laboratory environments.

The primary goal of EN 60068-2-67 is to simulate long-term exposure to humid environments to identify potential weaknesses in components, enhancing the reliability and safety of electrotechnical products. Note that this standard focuses on internal degradation from damp heat and does not address external factors like corrosion or mechanical deformation.

Key Topics

• Purpose and Scope
  The method targets small, non-hermetically sealed electrotechnical components subjected to steady-state damp heat. It aims to replicate an accelerated aging process to assess how damp environments affect component integrity over time.

• Test Procedure
  The test involves exposing the component to a controlled environment with constant relative humidity and elevated temperature to promote accelerated moisture penetration and thermal stress.

• Test Parameters

  • Steady-state conditions of damp heat
  • Controlled temperature and humidity settings
  • Defined duration to simulate long-term aging

• Limitations
  This standard does not cover corrosion, deformation, or other external environmental impacts. It is strictly meant for assessing internal moisture resistance over an accelerated timeframe.

• Safety and Compliance
  EN 60068-2-67 is recognized as a fundamental safety publication per IEC Guide 104, ensuring the standardized and rigorous evaluation of electrotechnical components' environmental resilience.

Applications

The EN 60068-2-67 damp heat accelerated test is widely used in industries requiring high reliability of small electrotechnical parts exposed to humid conditions:

• Component Manufacturers
  To validate product designs against moisture-induced failures before market release.

• Quality Assurance Laboratories
  For routine testing to ensure product consistency and adherence to environmental endurance specifications.

• Research and Development
  To study the influence of damp heat on novel materials and technologies within electronic components.

• Product Certification
  Assists in demonstrating compliance with environmental endurance standards for certifications and regulatory purposes.

• Electronics in Harsh Environments
  Industries like automotive, aerospace, and telecommunications use this testing method to guarantee the operational stability of devices under moisture-prone conditions.

Related Standards

• EN 60068 Series
  Other parts of the EN 60068 standard cover various environmental tests such as temperature cycling, vibration, and corrosion, providing comprehensive guidance for environmental qualification of electrotechnical products.

• IEC Guide 104
  Provides directives on safety publications, under which EN 60068-2-67 holds fundamental status.

• ISO/IEC 17025
  Credentials for laboratories performing environmental testing, ensuring quality and reliability in test execution.

• Corrosion Testing Standards
  Although EN 60068-2-67 excludes corrosion testing, related standards like ISO 9227 provide complementary procedures for corrosion assessment.

---

By adhering to EN 60068-2-67:1996, manufacturers and testers can robustly evaluate the moisture resistance of sensitive electrotechnical components. This standard plays a crucial role in enhancing product durability, ensuring safety, and supporting compliance within the electrical and electronics industry.
