Environmental testing - Part 2-78: Tests - Test Cab: Damp heat, steady state

Environmental testing - Part 2-78: Tests - Test Cab: Damp heat, steady state

Provides a test method for determining the suitability of electrotechnical products, components or equipment for transportation, storage and use under conditions of high humidity. The test is primarily intended to permit the observation of the effect of high humidity at constant temperature without condensation on the specimen over a prescribed period. This test provides a number of preferred severities of high temperature, high humidity and test duration. The test can be applied to both heat-dissipating and non-heat dissipating specimens. The test is applicable to small equipment or components as well as large equipment having complex interconnections with test equipment external to the chamber, requiring a set-up time which prevents the use of preheating and the maintenance of specified conditions during the installation period.

Essais d'environnement - Partie 2-78: Essais - Essai Cab: Chaleur humide, essai continu

Fournit une méthode d'essai pour déterminer l'aptitude des produits électrotechniques, composants ou matériels, prévus pour être transportés, stockés et utilisés dans des conditions de forte humidité. Cet essai est principalement destiné à permettre l'observation sur une période prescrite des effets d'une forte humidité, à température constante, sans condensation sur le spécimen. Cet essai indique un certain nombre de sévérités préférentielles pour des températures élevées, une forte humidité et pour la durée d'essai. Cet essai peut s'appliquer à la fois à des spécimens dissipateurs d'énergie ou non dissipateurs d'énergie. Cet essai s'applique aussi bien à des petits matériels ou composants qu'à des matériels volumineux ayant des liaisons complexes avec des matériels d'essai situés à l'extérieur de l'étuve, et nécessitant des temps de mise en service qui empêchent d'avoir recours à un préchauffage et de maintenir les conditions climatiques spécifiées pendant la durée de l'installation.

Environmental testing - Part 2-80: Tests - Test Fi: Vibration - Mixed mode
SIST EN 60068-2-80:2005

Intended for general application for testing specimens when simulation is required of vibration excitation of a complex and mixed nature. The purpose of the test is to demonstrate the adequacy of the specimen to resist the specified mixed mode excitation without unacceptable degradation of its functional and/or structural performance. It is particularly useful for tailoring mixed mode environments where measured data are available for the real life environment. The test also helps reveal the accumulated effects of stress induced by random vibration, mixed with sine and/or random, and the resulting mechanical weakness and degradation in specified performances, and to use this information, in conjunction with the relevant specification, to assess the acceptability of specimens. In some cases, this standard may also be used to demonstrate the mechanical robustness of specimens. This standard is applicable to specimens which may be subjected to vibration of a random and/or a combination of random and deterministic nature resulting from transportation or real life environments, for example in aircraft, space vehicles and for items in their transportation container when the latter may be considered as part of the specimen itself. Although primarily intended for electrotechnical specimens, this standard is not restricted to such specimens and may be used in other fields where desired.

Environmental testing - Part 3-8: Supporting documentation and guidance - Selecting amongst vibration tests
SIST EN 60068-3-8:2004

Provides guidance for selecting amongst the EN 60068-2 stationary vibration test methods Fc sinusoidal, Fh random and F(x) Mixed mode vibration. The different steady-state test methods and their aims are briefly described in Clause 4. Transient test methods are not included. For vibration testing, the environmental conditions, especially the dynamic conditions for the specimen, should be known. This standard helps to collect information about the environmental conditions (Clause 5), to estimate or measure the dynamic conditions (Clause 6) and gives examples to enable decisions to be made on the most applicable environmental vibration test method. Starting from the condition, the method of selecting the appropriate test is given. Since real life vibration conditions are dominated by vibration of a random nature, random testing should be the commonly used method, see Table 1, Clause 7. The methods included hereafter may be used to examine the vibration response of a specimen under test before, during and after vibration testing. The selection for the appropriate excitation method is described in Clause 8 and tabulated in Table 2. In this standard specification, writers will find information concerning vibration test methods and guidance for their selection. For guidance on test parameters, or severities of one of the test methods, reference should be made to the normative references. Has the status of a basic safety publication in accordance with IEC Guide 104.

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.
