This document specifies a test method to determine the top layer delamination of multilayer parquet elements according to EN 13489 with different structures, dimensions and adhesives for internal use as flooring, at the time of the first delivery of the product. The document specifies 2 pre-treatments (PT1 and PT2) of the test specimens. The test methods described in this document allow to determine the minimum top layer bonding quality, also for the use application on floor heating, and for the identification of bonding failure. NOTE 1 For this application, the pre-treatments have proven to be suitable. This document does not apply to the bonding quality of plywood if it is in use in the multilayer parquet construction. NOTE 2 This standard doesn t allow to estimate the compatibility of use in wet conditions.
