Lecture: THE INI-EVA RANKING: THE TRUTH ABOUT RESILIENT LAYERS
Author(s): Verbandt Filip
Summary:
Many types of resilient layers are available on the market. They are made of plastic foam; rubber; mineral wool; felt; metal; coconut; cork … and they are all characterized by one single parameter. This parameter is determined in a certified laboratory. The time consuming and expensive tests according to the certified ISO 10140 standard make it difficult and almost impossible to organize meaningful round robin tests. The resilient layers can be combined with many other layers such as leveling layers, floor heating layers, different thicknesses of screeds and finishing top layers. This results in an enormous number of test results and confuses architects, contractors and the consumer. This paper describes a new method based on the ISO 16251 that allows a comparison in an objective, fast and reliable way different resilient layers under different circumstances. A very good agreement is found between the new and certified test. The development, method, setup, testing and accuracy analysis were performed over a period of three years. The robustness of the technique will be demonstrated in the paper. This led to a new classification system for the impact noise insulation of resilient layers when using the new measuring procedure. We call it for the moment, the EVA quality impact noise insulation ranking (INI-EVA ranking) and give the in our laboratory tested resilient layer products an INI performance EVA label. A dozen of manufactures have tested more than 50 different products of under screeds and underlays for laminate floors with the new method. They have also successfully used the technique for the development of new products.
