Aging and temperature dependency of acoustic PVC floor covering under French certification NF UPEC.A+

摘要

France like some European countries takes into account intrinsic acoustic performance of floor coverings to reach building regulation requirements in terms of impact noise level. In this context PVC floor covering market developed in France yielding to the performance certification of these products under the label UPECA+ about ten years ago. The concerned industrials gathered within the SFEC (Syndicat Francais des Enducteurs Calandreurs) anxious to answer market questionings about the time durability of their performances launched a wide study on the subject in collaboration with the CSTB and the support of the DGUHC (housing ministry). Six products have been followed during five years both in laboratory (natural aging without particular promptings) and in-situ (two lived-in housings). Intermediate observations of in-situ measurements campaigns led us to complete these investigations by a study on temperature base floor impact on acoustic performances. The main results are the time stability of acoustic performances of certified products as well as their strong dependency on surface base floor temperature.
