Technical report regarding precision data for standards EN 12720, EN 12721, EN 12722, EN 15185 and EN 15186

This document specifies repeatability standard deviation and reproducibility standard deviation for results obtained from tests methods carried out according to following standards:
-   EN 12720:2009+A1:2013, Furniture - Assessment of surface resistance to cold liquids,
-   EN 12721:2009+A1:2013, Furniture - Assessment of surface resistance to wet heat,
-   EN 12722:2009+A1:2013, Furniture - Assessment of surface resistance to dry heat,
-   EN 15185:2011, Furniture - Assessment of the surface resistance to abrasion,
-   EN 15186:2012, Furniture - Assessment of the surface resistance to scratching,
in order to provide the accuracy of results.
The above standards deal with all rigid furniture surfaces regardless of materials and they not apply to leather and textile surfaces.

Technischer Bericht über Präzisionsdaten der Normen EN 12720, EN 12721, EN 12722, EN 15185 und EN 15186

Rapport technique sur les données de fidélité concernant les normes EN 12720, EN 12721, EN 12722, EN 15185 et EN 15186

Le présent document spécifie des écarts-types de répétabilité et des écarts-types de reproductibilité concernant les résultats obtenus par l’application de méthodes d’essai selon les normes suivantes :
- EN 12720:2009+A1:2013, Ameublement - Évaluation de la résistance de la surface aux liquides froids,
- EN 12721:2009+A1:2013, Ameublement - Évaluation de la résistance de la surface à la chaleur humide,

- EN 15186:2012, Ameublement - Évaluation de la résistance de la surface à la rayure,
afin d’être en mesure de fournir l’exactitude de ces résultats.
Les normes susmentionnées s’appliquent à toutes les surfaces rigides des meubles, indépendamment des matériaux, et ne s’appliquent pas aux surfaces en cuir et textiles.

Tehnično poročilo o natančnosti rezultatov, dobljenih v skladu s standardi EN 12720, EN 12721, EN 12722, EN 15185 in EN 15186

Ta dokument določa standardni odklon ponovljivosti in standardni odklon obnovljivosti za rezultate, dobljene pri preskusnih metodah, izvedenih v skladu z naslednjimi standardi:
– EN 12720:2009+A1:2013, Pohištvo – ocenjevanje odpornosti površine proti hladnim tekočinam,
– EN 12721:2009+A1:2013, Pohištvo – ocenjevanje odpornosti površine proti vlažni toploti,
– EN 12722:2009+A1:2013, Pohištvo – ocenjevanje odpornosti površine proti suhi toploti,
– EN 15185:2011, Pohištvo – ocenjevanje odpornosti površine proti obrabi,
– EN 15186:2012, Pohištvo – ocenjevanje odpornosti površine proti razenju,
za zagotavljanje natančnosti rezultatov.
Zgornji standardi obravnavajo vse trdne pohištvene površine ne glede na materiale, vendar se ne uporabljajo za usnjene in tekstilne površine.
