Laboratory tests on the RENOVA system.
In order to define the mechanical stresses on the RENOVA and
RENOVA ULTRA systems (hereinafter “the RENOVA systems”,
Wavin Italia SpA has conducted a series of laboratory tests.
In the absence of a specific standard for radiant screeds,
the tests were conducted with reference to the Technical
Construction Standards of the Ministerial Decree of 17th
January 2018.
The mechanical characteristics of the high-resistance,
reduced fluid screed were obtained through the determination
of the flexural and compression strength, determined on
regularly formed and cured specimens in compliance with the
UNI EN 13892-2 standard, the obligatory reference for this
category of products.

Concentrated Load Tests. The purpose of the test is to
simulate the reaction of the RENOVA Systems to stresses
deriving from the action of concentrated loads, such as furniture
or furnishings.
The concentrated load tests were carried out on 100x100 cm
panels with a punch of suitable dimensions according to the
Ministerial Decree of 17 January 2018 for concentrated vertical
loads.
Note: the Ministerial Decree of 17 January 2018 sets test values
for the entire floor. The values reported are relative to tests
performed for the sole layer corresponding to the RENOVA
Systems, as if it were the whole floor instead of just a section of it.
Uniformly Distributed Load Tests. The purpose of the test is to
simulate the application of the RENOVA Systems on rigid sub-
floors, such as a concrete floor "protected" by a floor covering,
such as a ceramic covering.
The uniformly distributed load tests were carried out on
100x100 cm panels placed on a contrast surface (rigid support)
according to the Ministerial Decree of 17 January 2018 for
uniformly distributed vertical loads.
