EN 661 Flexible Floor Coverings - Standard Test Method for Determining the Permeability of Water

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 661 testing. This European standard specifies a method for determining the horizontal propagation velocity of water in a flexible floor covering adhered to a non-absorbent base.

The condition of the subfloor at the time of application always affects the thickness of the resilient flooring layers. It is necessary to make sure that concrete subfloors are completely cleaned and smooth. Subfloors with roughness, dirt or dented areas will over time adversely affect the appearance of the pavement.

A thinner coating should be preferred, as concrete provides plenty of stability and support. If the veneer is installed over wooden subfloors, an extra layer of wood with a minimum thickness of 6 mm should be added. The wood floor also needs to be clean of dust or debris. If the subfloor is ceramic, porcelain or tile, a thicker coating is recommended.

Flexible sheet flooring is an engineered combination of polymer materials produced in different widths and a continuous length. These coatings are well suited for many types of residential and commercial applications, from light to heavy traffic areas. Flexible tile products have expanded significantly in recent years. These coatings are produced in a wide variety of sizes and thicknesses. The base structure varies from product to product, but the sole is primarily a limestone composite material that is formed by heat and pressure into solid layers of varying thickness and takes the desired shape.

In the production of resilient flooring, all raw materials (polyvinyl chloride resins, plasticizers, pigments, stabilizers and installation media) are checked to ensure they meet minimum production quality standards. It is necessary to ensure that all components are chemically and physically sufficient and of the desired thickness to obtain a quality product.
