4.3
When tested in accordance with the test methods specified in 5.1.1 to 5.1.12, the dimensional tolerances and mass per unit area of the sheets shall conform to the requirements given in Table 2. The test methods given in Table 2 are used for initial type testing, and are the reference test methods. Any other indirect test method may be chosen provided that it is sufficiently accurate to ensure that the dimensions of the products meet the requirements of Table 2 and as far as a correlation is demonstrated with the concerned reference test method.
The overall sheet thickness at any point shall not vary by more than ± 0,5 mm of this value. Mass per unit area 5.1.5 The nominal mass per unit area of the sheet shall be declared in grams per square metre. The mass per unit area of a sheet shall be not less than 95 % of the declared nominal mass per unit area. Variation of mass per unit area 5.1.6 The mass per unit area of each cut section across the width of the sheet shall not vary by more than ± 6 % from the calculated mean mass per unit area of the cut sections. Sheet length 5.1.7 The sheet length shall be within the interval from: - 0 mm to +12 mm of the declared sheet length for sheet length up to 3 000 mm;
- 0 % to +0,40 % of the declared sheet length for sheet length greater than 3 000 mm. Sheet width 5.1.7 The sheet width shall be within the interval from – 2 mm to + 6 mm of the declared sheet width. Deviation from rectangular shape (only for rectangular sheets) 5.1.8 The difference between the lengths of the two diagonals of the sheet shall be less than 0,5 % of the width of the sheet. Wall and internal feature thickness 5.1.9 When required, the nominal wall and internal feature thicknesses and the tolerances shall be declared. Sheet flatness
5.1.10 The deviation from flat across the width of the sheet shall be ≤ 5 mm per meter of width. The deviation from flat along the length of the sheet shall be ≤ 5 mm/linear metre. Out of square 5.1.11 The deviation of squareness of the sheet shall be < 5 mm per meter of width. Lateral curvature 5.1.12 The maximum distance between the straight edge and the side(s) of the sheet shall be < 5 mm/m.
4.3 Spectral characteristics The spectral characteristics of multiwall PC sheets shall be assessed when subject to regulatory requirement. The spectral characteristics of a multiwall PC sheet include the luminous and solar characteristics, and the reflexion and transmission characteristics. The multiwall PC sheets are defined by their geometry, colour and mass per unit area. A change of one of these physical characteristics affects the spectral characteristics of a multiwall PC sheet. The spectral characteristics shall be measured according to EN 14500 considering the samples cut from multiwall PC sheets as thick translucent samples (see EN 14500:2008, 6.3.2). NOTE 1 The normal-hemispherical light transmittance, 2v,n-h, and the normal-hemispherical solar transmittance, 2e,n-h, as designated in EN 14500 correspond respectively to the light transmittance, 2v, and the solar direct transmittance, 2e, as designated in EN 410. The test samples shall be of sufficient size to cover its structural aspects. SIST EN 16153:2013

For a declared value of the normal-hemispherical light transmittance equal to 60 %, the actual normal-hemispherical light transmittance of a sheet may be included between 55 % and 65 %. NOTE 2 The normal-hemispherical light transmittance, 2v,n-h, corresponds to the total luminous transmittance, 2D65, as stated in EN 1873 and ETA-Guideline 010. For unsymmetrical in-plan cross-section multiwall PC sheets, in the case where both sides of the sheets may be considered as an external surface, the reflectance measurements shall be carried out on each external face. In that case, the superscript “ ‘ “ shall be used to indicate for the reflectance factor of the opposite external face of the multiwall PC sheet from the first one. 4.4 Total solar energy transmittance The total solar energy transmittance, g, as defined in EN 410 shall be determined either by calculation according to 5.2.1 or by measurement according to 5.2.2. The calculation method is applicable only to multiwall PC sheets with symmetrical in-plane cross-section (see 3.1.3) or symmetrical in-plane mirror (see 3.1.4). Where the calculation method is not applicable, then the total solar energy transmittance shall be measured. 4.5 Impact resistance 4.5.1 Small hard body impact resistance The small hard body impact resistance shall be assessed when subject to regulatory requirement. The small hard body impact resistance shall be evaluated by determining the impact behaviour according to 5.5. Failure occurs when a crack or a break appears on the test specimen. White discolorations are not considered as cracks. When ten test specimens taken from three sheets are submitted to the test, no failure shall occur. 4.5.2 Large soft body impact resistance The resistance to large soft body impact depends very heavily on the method of installation and the roof system into which the light transmitting sheet is incorporated, rather than a property of the sheet itself. The large soft body impact resistance of the same product is likely to be different when the same product is used in different roofing systems and/or installed with different methods of installation, and therefore cannot be declared for a particular product. In the absence of an appropriate European test method for sheets, the manufacturer may declare the method of installation for each application, which shall consider the large soft body impact resistance. The manufacturer shall assess the large soft body impact resistance separately in accordance with ETAG 010, EN 1873, EN 14963 or individual national safety requirements for each such application. The test report shall record the test method and the manufacturer's instructions for the installation. NOTE At the date of publication of this document, the following national safety requirements have been identified: DS 1133:1987 [2] and ACR[M]001:2005 [1]. SIST EN 16153:2013

The durability of the sheets shall be demonstrated by testing after artificial ageing the variation of the yellowness index and the light transmittance with the same level of radiant exposure in the total daylight and declaring the results according to 4.6.2. 4.6.2 Classification according to the radiant exposure The exposure to artificial ageing shall be carried out in accordance with 5.3 using one of the classes given in Table 3.

In the case of an exposure to a radiant exposure greater than 18 GJ/m2, the actual value may be declared by the manufacturer to allow the customer to determine the suitability of the sheets to exposure in areas where the conditions are particularly severe. EXAMPLE An uncoloured sheet, with the following characteristics:  YI = 2 before ageing and YI ≤ 12 after ageing: ûYI ≤ 10  2v = 80 % before ageing and 2v ≥ 75 % after ageing: û2v ≤ 5 % is classified ûA. 4.6.3 Variations of yellowness index and light transmittance after artificial ageing To evaluate the durability, the variations of the yellowness index and light transmittance after artificial ageing shall be assessed when subject to regulatory requirement.

The deformation behaviour of the sheets shall be determined in accordance with 5.6. The bending stiffness, Bx and By, the shear stiffness, Sy, and the buckling moment, Mb, shall be declared. These values may be used for determining the behaviour of the sheets and for comparison of the results of full scale tests performed with other sheets. 4.8 Airborne sound insulation The method(s) of installation shall consider the airborne sound insulation. The sound reduction index, Rw (C;Ctr), of the multiwall sheets shall be assessed when subject to regulatory requirement. The sound reduction index, Rw (C;Ctr), shall be measured in accordance with 5.7 and declared. 4.9 Thermal transmittance The thermal transmittance, U value, shall be assessed when subject to regulatory requirement. SIST EN 16153:2013

The water vapour permeability, /, shall be assessed when subject to regulatory requirement. The standard value of the water vapour permeability, /, of PC sheets is 3,8 x 10-5 mg/m h ⋅Pa and it shall be declared. When a better performance is sought for declaration, the water vapour permeability of the material used for the sheet shall be determined according to EN ISO 12572. 4.11 Water/air tightness The water/air tightness shall be assessed when subject to regulatory requirement.
PC sheets are deemed to satisfy the water/air tightness requirement without the need for testing provided that there are no defects in the sheets. The absence of defects (e.g. holes) shall be evaluated by examination of visual appearance according to 4.1. 4.12 Linear thermal expansion The linear thermal expansion, ., shall be assessed when subject to regulatory requirement. The value of the coefficient of linear thermal expansion, ., of the PC material is 65 x 10-6 K-1. When a higher performance is sought for declaration, the thermal expansion coefficient of the material used for the sheet shall be determined according to ISO 11359-2. For practical purposes, the coefficient of linear thermal expansion is valid for temperatures in the range -20 °C to 70 °C. 4.13 Reaction to fire The reaction to fire shall be assessed when subject to regulatory requirement. The reaction to fire performance of the sheets shall be determined in accordance with 5.8 and declared by the manufacturer according to EN 13501-1. 4.14 External fire performance External fire performance shall be assessed when subject to regulatory requirements. The product shall be tested using the test method(s) as referred to and classified in accordance with EN 13501-5. The products to be tested shall be installed, in addition to the general provisions given in the relevant test method, in a manner representative of their intended end use. 4.15 Resistance to fire Resistance to fire shall be assessed when subject to regulatory requirements. The product shall be tested using the test method(s) as referred to and classified in accordance with EN 13501-2. In general, the product cannot be classified. “No performance determined” (NPD) should therefore be used. Where required by a particular test method, and in addition to any specific requirements in that test method, the product shall be mounted and fixed for testing in a manner representative of its intended end use. SIST EN 16153:2013

4.18 Dangerous substances National regulations on dangerous substances may require verification and declaration on release, and sometimes content, when construction products covered by this standard are placed on those markets. In the absence of European harmonised test methods, verification and declaration on release/content should be done taking into account national provisions in the place of use. NOTE An informative database covering European and national provisions on dangerous substances is available at the Construction web site on EUROPA accessed through: http://ec.europa.eu/enterprise/construction/cpd-ds/. 4.19 Resistance to fixings The principles of fixing of the sheets shall be declared. The method(s) of installation shall consider resistance to wind loads, snow loads and resistance to large soft body impact which may be assessed separately, e.g. in accordance with the requirements given in EN 14963, EN 1873, ETAG 010, or individual safety national requirements.
4.20 Temporary protective coverings For shipping and handling, the surfaces of the sheets, as delivered, may be protected by suitable materials, e.g. a polyethylene film, which is removable without causing surface contamination or damage. 5 Test and calculation methods 5.1 Dimensional tolerances and mass per unit area 5.1.1 General The measurements shall be carried out at an ambient temperature of (20 ± 5) °C. In case of dispute, the measurements shall be made using standard atmosphere 23/50, Class 2, according to EN ISO 291. For measurements made under ambient conditions, due allowance shall be made for dimensional changes due to the differences in temperature and relative humidity between test locations. All tolerances shall apply to the declared values. 5.1.2 Apparatus 5.1.2.1 Micrometer, capable of measuring to an accuracy of 0,01 mm, with hemispherical anvils of 5 mm in diameter.
