PD CEN/TR 17292 is a Technical report that pecifies repeatability standard deviation and reproducibility standard deviation for results obtained from test methods carried out according to the 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 do not apply to leather and textile surfaces.
PD CEN/TR 17292 on precision data for aforementioned standards is useful for:
In the context of PD CEN/TR 17292, precision is defined as the closeness of agreement between independent test results obtained under stipulated conditions.
The accuracy is provided by repeatability standard deviation and reproducibility standard deviation. On the basis of an inter-laboratory study for test methods involved, in which from one to three operators of participating’s tested the samples prepared to cover the current range of surfaces, the repeatability and reproducibility standard deviations and limits were calculated.
PD CEN/TR 17292 covers repeatability standard deviation and reproducibility standard deviation including parameters such as abrasion, scratching, cold liquids, dry heat and wet heat.
Thus, PD CEN/TR 17292 is your companion-guide to ensure accurate test results of the aforementioned standards.
