Développement de normes à partir de tests du matériel et de contrôle de qualité menés sur les matériaux à changement de phase.

Development of standards from materials testing and quality control of PCM.

Auteurs : MEHLING H., EBERT H. P., SCHOSSIG P.

Résumé

During recent years, more and more commercial applications of PCM can be seen on the market. For any kind of product development, the relevant material properties have to be known with sufficient accuracy. During the production process, tests have to be done to ensure that the PCM, or the product that contains PCM, has a constant quality. For PCM, no special standards have been available until now. Even worse, common standards for calorimetry can lead to large errors when applied to PCM. To solve this problem, the "RALGütegemeinschaft PCM e.V." was founded in 2005 by several companies to have a quality label for PCM that by setting standards assures quality. The ZAE Bayern and the Fraunhofer Institute FhG-ISE were then contracted to develop standards for materials testing and quality control. The focus points were the testing of PCM-materials and PCM-composite materials with respect to the stored heat as a function of temperature, the reproducibility of the phase change and the thermal conductivity. The main problems in materials testing and the resulting guidelines regarding the "stored heat as a function of temperature" are presented here. The quality label was granted in spring 2006.
