The obtained corrected analytical value of migration. C, of any of the heavy metals from thermoplastics rigid protective wallcovering panel, as listed in Table 2, except of antimony (Sb), shall not exceed the related maximum migration value, specified also therein.
4.3.2 If so, the migration of heavy metals from the thermoplastics rigid protective wallcovering panel, as listed in Table 2, shall be expressed, as:
a) for antimony (Sb), as indication of the achieved corrected analytical value, C, in mg/kg
EXAMPLES
200 mg/kg
0 mg/kg
b) for barium (Ba) or selenium (Se), as indication “Compliant”.
4.4 Impact resistance
The impact resistance performance of thermoplastics rigid protective wallcovering panels shall be determined according to 5.5 and the value of the 50 % impact-failure energy (E50) reported.
The impact resistance performance of thermoplastics rigid protective walicovering panel shall have the 50 % impact-failure energy (E50) higher than 15 J and, if so, the performance of this characteristic shall be expressed as indication”> 15 J”.
NOTE The threshold limit of 15 J is considered as protection from the risk of break of the thermoplastics rigid protective wallcovering panel and of the wall itself, on which surface such panels are mounted.
4.5 Sound absorption
The sound absorption performance of a thermoplastics rigid protective wailcovering panel shall be measured according to 5.6 and expressed as an indication of a value of the sound absorption coefficient,
4.6 Thermal resistance
The performance of thermal resistance, R, of the thermoplastics rigid protective wallcovering panel shall be determined either by calculation, in accordance with to 5.7 a), or by testing, with 5.7 b).
NOTE The calculation method is considered as the reference method.
The performance of this characteristic of the thermoplastics rigid protective wallcovering 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 m2’K/W) rounded to the nearest upper 0,01 m2K/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 wallcovering 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 wallcovering 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 16516:2017+A1:2020, HPLC method, or EN 717-1:2004.
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 wallcovering 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 12149: 1997, Clause 4 (Test A), and
NOTE For the antimony, it the level cannot be determined because of the low detection capacity, the analytical value, A, may be taken as zero.
b) a corrected value, C, calculated according the following equation, where B is analytical correction factor from Table 3 for the corresponding heavy metal:
C=A—(A x B)/100
EXAMPLE Analytical result for barium (A) is 600 and corresponding analytical correction factor in Table 3 (B) is 30 %.
Corrected analytical value, C = 600 – (600 x 30)/100 = 600 – 180 = 420 mg/kg 500 mg/kg.
This is regarded as satisfying the respective maximum migration criterion, specified in Table 2.BS EN 17104 pdf download.
