Overview

oSIST prEN 1013:2007 is a European standard developed by CEN that specifies the requirements and test methods for light transmitting single skin profiled plastic sheets. These sheets are designed for use in internal and external applications such as roofs, walls, and ceilings. The document addresses single-layer sheets as well as configurations where sheets are assembled into multi-layer constructions, ensuring optimal performance and durability.

This standard supersedes previous versions EN 1013-1 through EN 1013-5 and aligns with the essential requirements set by the EU Construction Products Directive. It covers comprehensive aspects including dimensional tolerances, light transmission, mechanical strength, durability, fire performance, and conformity evaluation to support reliable use of these plastic sheets in building construction.

Key Topics

• Scope and Application
  The standard applies to light transmitting single skin profiled plastics sheets used as building elements in both internal and external environments. It guides on single layer and multiple layer construction practices pertinent to roofs, walls, and ceilings.

• Physical and Mechanical Requirements
  Requirements include visual appearance standards to avoid defects such as holes, cracks, or bubbles larger than 1 mm, and for glass-fibre reinforced sheets, resin ribs and glass knots are limited in size. Dimensional tolerances and mass per square meter are clearly defined. Mechanical properties such as flexural and tensile strength, impact resistance, and resistance to deflection ensure structural integrity under various conditions.

• Durability and Thermal Performance
  The standard specifies thermal ageing resistance tests for thermoplastic sheets, including longitudinal reversion and profile retention. It also details water vapor permeability, water/air permeability, and linear thermal expansion coefficients to ascertain suitability in diverse environmental conditions.

• Fire Safety Requirements
  Reaction to fire is tested following European norms, including external fire performance. This is critical for safety compliance and integration of light transmitting plastic sheets in building constructions.

• Material Specific Tests
  For glass-fibre reinforced sheets, the standard mandates testing for glass-fibre content and Barcol hardness along with the adhesion of protective surface coatings. This ensures material composition and quality control.

• Testing and Conformity Evaluation
  oSIST prEN 1013:2007 outlines detailed test methods for dimensional verification, light transmission, artificial ageing, yellowness index measurement, mechanical tests, and fire classification. The evaluation of conformity includes initial type testing (ITT) and ongoing factory production control (FPC), supporting consistent product quality.

Applications

• Building Construction
  The standard is essential for manufacturers, architects, and builders using light transmitting plastic sheets for roofs, walls, and ceilings. These sheets offer natural daylighting while providing weather resistance and structural durability.

• Industrial and Commercial Facilities
  Light transmitting profiles are widely employed in industrial warehouses and commercial buildings where durable, translucent materials improve energy efficiency and indoor lighting conditions.

• Renovation and Facade Design
  Use of single skin profiled sheets facilitates renovation projects requiring lightweight and aesthetically pleasing cladding or roofing solutions, complying with modern safety and performance requirements.

• Multi-Layer Assemblies
  This standard supports configurations where single skin sheets are combined into multi-layer constructions to meet additional insulation or mechanical strength needs.

5.13 Reaction to fire
The reaction to fire shall be assessed when subject to regulatory requirement and may be assessed otherwise.
The reaction to fire performance of light transmitting profiled sheets shall be determined in accordance with
6.10 and declared by the manufacturer according to EN 13501-1.
Test samples shall be the same weight/thickness as the final product. Where there is a range of thicknesses
of product, the manufacturer can test 2 (or more) thicknesses of sample, and the poorer of the two results can
be applied to all products between the two thicknesses tested. Test results shall not be assumed to apply to
products thicker than the thickest sample tested, or thinner than the thinnest sample tested.
Test results on flat samples can be applied to all profiles within the product range provided the effect of the
profile does not add more than 30 % additional material.
Where the effect of the profile adds more than 30 % material, the thickness of the test sample shall be
increased to ensure the difference in material mass between the test sample and profiled sheet is less than
30 %.
Where the product has no surface protection on the inner surface of the product, or where the surface
protection on this surface is a co-extrusion of the same base material, or is less than 75 µm thick, then
samples can be tested either with or without this surface protection. The test results achieved can be applied
both to products with or without such surface protection.
Where the product has a surface protection which is not co-extruded of a similar material and is more than
75 µm thick, it shall be present on the specimens tested, and the results will only apply to specimens with
such surface protection.
5.14 External fire performance
The external fire performance shall be assessed when subject to regulatory requirement and may be
assessed otherwise.
The external fire performance of light transmitting profiled sheets shall be determined in accordance with 6.11
and declared by the manufacturer according to EN 13501-5.
Test samples shall be the same weight/thickness as the final product. Where there is a range of thicknesses
of product, the manufacturer can test 2 (or more) thicknesses of sample, and the poorer of the two results can
be applied to all products between the two thicknesses tested. Test results shall not be assumed to apply to
products thicker than the thickest sample tested, or thinner than the thinnest sample tested.
Material shall be tested as flat sheets for Test 2 of ENV 1187, and/or profiled sheets (with cover width 1 metre,
depth 30 mm to 35 mm and pitch 200 mm to 250 mm) for Tests 1, 3 and 4 of ENV 1187. Test results on these
samples can be applied to all profiles within the product range, provided the effect of the profile does not add
more than 30 % additional material.
Where the effect of the profile adds more than 30 % material, the thickness of the test sample shall be
increased to ensure the difference in material mass between the test sample and profiled sheet is less than
30 % (Test 2 of ENV 1187), or the profile tested shall be selected to ensure the difference in material mass
between the test sample and profiled sheet is less than 30 % (Tests 1, 3 and 4 of ENV 1187).
Samples shall be tested with the same surface protection as used on the external surface of the product.
However, where this surface protection is a coextrusion of the same base material, or is less than 75 µm thick,
then the test results can be applied to products which do not have any surface protection or which incorporate
alternative surface protection up to 75 µm thick.
Where the product has a surface protection which is not co-extruded of a similar material and is more than
75 µm thick, it shall be present on the specimens tested, and the results will only apply to specimens with

6 Test methods
6.1 Dimensional tolerances
6.1.1 General
The measurements shall be carried out either at an ambient temperature of (20 ± 5) °C or when it is not
possible a correction factor according to 5.12 shall be applied from the test temperature to 20 °C.
In case of rolls, the measurements are carried out on 10 pitches minimum or 1,5 m and the results are used to
determine the width and the shape of the profile.
The sheet is held in contact with a loading bar weighing 2,45 kg/m (30 mm loading width).
All tolerances shall apply to the values declared by the manufacturer.
6.1.2 Apparatus
6.1.2.1 Micrometer, capable of measuring to an accuracy of 0,01 mm, with hemispherical anvils of 5 mm
in diameter.
6.1.2.2 Three supports for the test piece.
6.1.2.3 Rigid template, corresponding to the shape of the sheet, given by the manufacturer, extending
beyond the full width of the sheet on each side, if necessary.
6.1.2.4 Measuring tape, capable of measuring the full length of the test piece to an accuracy of 1,0 mm.
6.1.2.5 Rectangular frame with vertical side and edge perpendicular to each other, accurate to 1 mm/m
width.
6.1.2.6 Short metal ruler, capable of measuring to an accuracy of 0,5 mm.
6.1.2.7 Metal straight edge, 2 metres long, the straightness of which is accurate to 0,5 mm.
6.1.2.8 Loading bar weighing 2,45 kg/m (30 mm loading width).
6.1.3 Test pieces
The test pieces shall be complete sheets, as delivered.
6.1.4 Sheet thickness
Sheet thickness shall be checked by nine measurements taken at random in the crowns, troughs and sides of
corrugation across the total sheet width at a distance of 20 mm from the one end. First and last
measurements to be within 25 mm of the sheet edges.
Record the nine values and calculate the mean of the nine recorded values to the nearest 0,01 mm.
6.1.5 Mass per square metre
The reference test method is to measure the weight of a full width sample of profiled sheet, approximately 1
metre length, to the nearest gram.
The ‘extended’ width of the profiled sample may be measured by:
 applying a piece of non-stretching tape (e.g. masking tape or glass filament tape) to the top surface
of the sample, perpendicular to the corrugations, ensuring it is in direct contact with the sample
surface across the whole width;
 mark the position of the edges of the sample sheet on the tape;
 remove the tape and apply to a flat surface;
 measure the distance between the two marks.
The overall width of the sample may be measured (between the 2 outer edges) to the nearest mm.
The length of the sample shall be measured (to the nearest mm) along both edges, and the mean calculated.
The reference value is the mass per square metre of the material in flat form, which shall be calculated as
follows:
Mass per square metre in flat form =  mass of the sample
(‘extended’ width x length) of the sample

Where a manufacturer declares the mass per linear metre of profiled sheet, this shall be calculated as follows:
Mass per linear metre of profiled sheet =  mass of the sample
length of the sample
Where a manufacturer declares the mass per square metre of profiled sheet, this shall be calculated as
follows:
Mass per square metre of profiled sheet =  mass of the sample
(overall width x length) of the sample

6.1.6 Cover width of a sheet
Position the upper template over the outer corrugation only, and use this to define the centre of the crown of
the corrugation; mark this on the test piece.
Repeat this operation at the other side of the sheet.
Measure the distance between the centre of the crown of the outer two corrugations.
The results shall be expressed as follows: the three values obtained at the middle and at both ends,
expressed in mm, to the nearest mm.
6.1.7 Shape of the sheet profile
The reference test method is to check the shape of the profile using a rigid template. Ensure the test piece is
held flat using the weighting bar and bring a rigid template (the same shape as the profile) into gentle contact
with the test piece. Check the gap between the test piece and the template at all points across the width of the
profile by trying to insert an appropriate diameter measuring bar between the test piece and the template.
With some processes (e.g. extrusion of thermoplastics) “rounding” or distortion of the profile does not occur,
and with these processes it may be possible to confirm the profile shape is correct simply by checking the
main dimensions of the corrugation (pitch, depth and width of crown and trough).
6.1.8 Sheet length
Measure, to the nearest mm, the total length of the sheet along both edges, record the values so obtained.
The results shall be expressed as follows: the mean of the two values, expressed in mm, to the nearest
millimetre.
6.1.9 Sheet straightness
Place the long straight rule along the two edges, and measure with the small ruler to the nearest 0,5 mm, the
maximum distance between the rule and the edge of the sheet, record the obtained value for each side of the
test piece.
The results shall be expressed as follows: the values of both lateral edges, expressed in mm, to the nearest
0,5 mm.
6.1.10 Squareness of a sheet
Place the test piece onto the rectangular frame. Push the test piece against the end of the frame, whilst
keeping the side of the test piece aligned with the side of the frame. Measure the maximum distance between
the end of the test piece and the square end of the rectangular frame, to an accuracy of 0,5 mm. Record in
mm/m width.
Repeat this operation at the other end of the sheet.
The results shall be expressed as follows: the values of both ends, expressed in mm/m, to the nearest 0,5 mm.
6.2 Light transmission
The total luminous transmittance of the sheet shall be determined in accordance with EN ISO 13468-1 or
ISO 13468-2 using five test specimens.
Alternative test methods may be used as factory production control provided that correlation of results with
EN ISO 13468-1 or ISO 13468-2 can be demonstrated.
6.3 Artificial ageing test method
Artificial ageing shall be carried out according to EN ISO 4892-2:1999 method A with the following conditions:
 spectral distribution as detailed in Table 1 of EN ISO 4892-2:1999,
 air temperature: (32 ± 2) °C,
 black standard temperature (BST): (65 ± 3) °C,
 relative humidity: (65 ± 10) % HR,
 time of spraying: 18 min and dry interval between spray
