BS EN 17104:2021 pdf free download – Thermoplastics rigid protective wallcovering panels for internal use in buildings – Performance characteristics.
The performance of this characteristic of the thermoplastics rigid protective wailcovering panel shall be expressed as an indication of the 23 °C value of thermal resistance R, in m2•K/W.
The performance shall be expressed as an indication of the value (in m2K/W) rounded to the nearest upper 0,01 m2.K/W.
EXAMPLE Value 0,025 m2•K/W expressed as 0,03 m2.K/W.
5 Testing, assessment and sampling methods
5.1 Reaction to fire
The reaction to fire performance of the thermoplastics rigid protective wailcovering panel shall be determined in accordance with the test method(s), given in the standard(s), referred in EN 13501-1:2018, for the claimed class of the reaction to fire performance.
The test specimens of the thermoplastics rigid protective walicovering panel shall be tested, where relevant, considering the substrate according to EN 13238:2010, Table 1.
5.2 Emissions of volatile organic compounds (VOC) with exception of formaldehyde
The emission of volatile organic compounds (VOC) from thermoplastics rigid protective wallcovering panel shall be determined according to EN 16516:2017+A1:2020, GC-MS method.
5.3 Emission of formaldehyde
The emission of formaldehyde from thermoplastics rigid protective walicovering panel shall be determined according to either EN 165 16:20 17+A1:2020, HPLC method, or EN 7 17-1:2004.
NOTE Method according to EN 165 16:2017+A1:2020 is considered as the referenced method.
5.4 Migration of heavy metals
For performance of migration of any of the heavy metals from thermoplastic rigid protective walicovering panel, as listed in Table 2, the following values (both in mg/kg), shall be determined:
a) an analytical value, A, obtained in the test performed in accordance with EN 12 149:1997, Clause 4 (Test A), and
NOTE For the antimony, if the level cannot be determined because of the low detection capacity, the analytical value, A, may be taken as zero.
5.5 Impact resistance
The impact resistance performance of thermoplastics rigid protective wailcovering panel shall be determined according to EN ISO 6603-1:2000, Method A, with the test conditions shall be as follow:
— striker diameter: (20 ± 0,2) mm;
— surface area of test specimens: (60 ± 2) mm2
— number of specimens: at least 30 test specimens shall be used (10 test specimens for pretesting to determine the starting energy);
— conditions for conditioning of test specimens and testing: (23 ± 2) °C and (50 ± 5) % RH.
The impact resistance performance shall be dealt with by the 50 % impact-failure energy (E50), the energy that causes no more than half of the test specimens to fail, as defined hereafter.
Failure occurs, when a crack or a break appears on the test specimen (see examples given in Figure 2). White discolorations are not considered as cracks.
5.6 Sound absorption
Performance of the sound absorption of thermoplastics rigid protective wailcovering panel shall be measured in accordance with EN ISO 354:2003 and reported as the single value of the sound absorption coefficient, a. according to EN ISO 11654:1997.
5.7 Thermal resistance
The performance of thermal resistance, R, of the thermoplastics rigid protective walicovering panel shall he determined on one of the following ways.
