Environmental testing - Part 3-4: Supporting documentation and guidance - Damp heat tests
Provides the necessary information to assist in preparing relevant specifications, such as standards for components or equipment, in order to select appropriate tests and test severities for specific products and, in some cases, specific types of application. The object of damp heat tests is to determine the ability of products to withstand the stresses occurring in a high relative humidity environment, with or without condensation, and with special regard to variations of electrical and mechanical characteristics. Damp heat tests may also be utilized to check the resistance of a specimen to some forms of corrosion attack.

Rassemble les informations nécessaires aux rédacteurs qui, lors de l'établissement d'une spécification particulière telles que des normes pour les composants ou les matériels, choisissent les essais appropriés et leurs sévérités pour un produit particulier et, dans certain cas, pour des types d'application donnés. Le but de ces essais de chaleur humide est de déterminer l'aptitude des produits à supporter les contraintes d'un environnement à forte humidité relative, avec ou sans condensation, et plus particulièrement de déterminer les variations de leurs caractéristiques électriques et mécaniques. Les essais de chaleur humide peuvent aussi être appliqués en vue de vérifier la résistance d'un spécimen à certaines formes d'attaque par corrosion.

Overview
EN 60068-3-4:2002 (Environmental testing - Part 3-4: Supporting documentation and guidance - Damp heat tests) is a CLC/CENELEC adoption of IEC 60068-3-4:2001. This informative guidance document supports the selection and specification of damp heat tests for electrotechnical products and components. Its purpose is to help standards writers, specifiers and test engineers choose appropriate test types and severities to assess performance in high relative humidity environments, with or without condensation.
Key topics
- Purpose of damp heat tests: guidance on using damp heat to determine product resistance to high humidity, condensation and related stresses.
- Selection of tests and severities: how to determine which test procedure and severity level are relevant for specific products or application types.
- Electrical and mechanical characteristic variation: emphasis on monitoring changes in electrical and mechanical performance during/after damp heat exposure.
- Corrosion considerations: use of damp heat tests to check susceptibility to some forms of corrosion attack.
- Supporting documentation: recommended information to include in specifications and test plans; annex A provided as informative guidance.
- Harmonization with other IEC/EN test methods: positions Part 3-4 as complementary to the IEC 60068 family of methods (Part 1 & Part 2 series).
Practical applications
- Use EN 60068-3-4 when preparing product or component specifications that require environmental qualification for humidity exposure.
- Apply the guidance to define realistic test programs for electronics, electrotechnical equipment and assemblies destined for humid or condensing environments.
- Aid procurement, quality and compliance teams in specifying humidity test types and severities for supplier testing and acceptance criteria.
- Support environmental test laboratories in interpreting product- or application-specific test selection and reporting expectations.
Who should use this standard
- Standards developers and technical committees writing component or equipment standards.
- Test engineers and environmental laboratories designing damp heat test campaigns.
- Product design and reliability engineers validating humidity resistance.
- Quality assurance, certification bodies and procurement specialists who require clear humidity-test specifications.
Related standards
Relevant members of the IEC/EN 60068 family referenced alongside EN 60068-3-4 include:
