Dimensional stability

The test is performed in accordance with the Draft European Standard EN-1910. The test consists in the reproduction of damp environments (20 º C and 85% RH) in a conditioned chamber with the dimensions of a standard room. These environments are maintained for long periods at the end of which the deformation of the slats (bends, warps, swelling) are measured.

Resistance to abrasion

This test evaluates the performance of the flooring against dynamic effects such as those produced, for example, by falling objects from a certain height. The test consists of dropping a 500 g steel ball from various heights. What is sought with this test is the maximum drop height, before permanent damage to the varnish is produced, as well as the dimensions of the imprints produced by the impact.

 

Resistance to household products

The test is performed according to the procedure described in the UNE EN 438.2 standard, section 15. In this test, the wood flooring makes contact with various substances commonly used in the home (food products, detergents, acids, etc.) The contact time varies according to the nature of the product, from 24 hours to 10 min. The attack, the changes in gloss and the abnormal colorations of the test specimen are evaluated.

Hardness

The resistance that a material has against the penetration of another. There are various systems to evaluate the hardness of the wood: Brinnell, Janka and Monin. The data shown below for timber developed by IMA are derived from the Monin hardness test. This test is that which is required by the Spanish standard, UNE 56-534. The method consists of applying a load of 100 kg per cm of sample width on the test specimen using a steel cylinder, and transversely with regards to the fibre. The hardness is the inverse of the depth of the imprint left by the cylinder on the test specimen, detergent, acid, etc.) The contact time varies according to the nature of the product, from 24 hours to 10 min. The attack, the changes in gloss and the abnormal colorations of the test specimen are evaluated.

 

Resistance of the varnish to light

The test is performed by applying the method described in the EN 438.2 standard, section 16. In this test, the varnish is subjected to an accelerated aging cycle, which entails exposure to a xenon arc lamp in an atmosphere of relative humidity and specific temperature. The colour change of the test piece is then evaluated.

Thermal Conductivity

Thermal conductivity is the heat energy transferred per unit time and per unit surface area of the sample when a specific temperature difference between the face and counter-face is established. The lower the conductivity, the greater the thermal insulation and therefore the greater the energy cost savings. The thermal conductivity is measured by applying the method described in the UNE 92-201 standard 92-201 in an atmosphere of relative humidity and specific temperature. The colour change of the test piece is then evaluated.

 

Resistance to impact

This test evaluates the performance of the flooring against dynamic effects such as those produced, for example, by falling objects from a certain height. The test consists of dropping a 500 g steel ball from various heights. What is sought with this test is the maximum drop height, before permanent damage to the varnish is produced, as well as the dimensions of the imprints produced by the impact.

Scratch performance

Scratch resistance is evaluated by applying the method described in the UNE EN 438.2 standard, section 14. This resistance is evaluated by the minimum force applied to a diamond tip with a pre-defined geometry to produce an imprint on the varnish which is visible to the naked eye.

 

Formaldehyde emissions

Formaldehyde is a component of wood adhesives that is considered toxic at certain levels of emission. The majority of developed countries have increasingly limiting health regulations regarding the content of formaldehyde in industrial processed wood. The result obtained regarding the content of formaldehyde in the IMA laminate flooring is described in the UNE EN 120 standard, which is class E1 (less than 8 mg per 100 g of product mass).

Impact noise insulation

It is the reduction of the standardised impact noise level that a coating material installed on a slab or floor allows in the underlying premises. Other types of wood flooring, such as wood flooring on battens or mosaic wood flooring on mortar are unable to meet the specification of the basic building standard NBE CA-88 of 80 dBA over the majority of the various combinations of the most common floor slabs used in construction. IMA laminate flooring installed on 3 mm polyethylene foam provides an impact noise reduction of 18 dBA.
