4 General
Corrugated bitumen sheets are produced using a homogeneous mixture of organic and/or inorganic fibres and
bitumen. The shape and the structure of corrugated bitumen sheets and the quality of the raw materials
guarantee the properties.
Corrugated bitumen sheets may be spun-dyed. They may also be supplied with a coloured or colourless
adhesive surface coating, which in turn may or may not have a covering of granules or fine flakes.
Corrugated bitumen sheets may be manufactured as a mono-layer or a multi-layer product.
Corrugated bitumen sheets are divided into category R and category S depending on their mechanical
properties. For category R, all mechanical properties have to pass the threshold values of that category.
For roofing applications, category R products are suitable for most climatic conditions, while Category S
products may require special installation depending on the climatic conditions.
For cladding applications, both categories are suitable.
The manufacturer’s installation guide shall be consulted to ensure that the product is installed in the correct
manner for its category.

7.2.1 Bending under downward load
7.2.1.1 Equipment
The equipment is shown in Figure 8. It consists of:
 strong horizontal bench larger than the corrugated bitumen sheet;
 four square tubes MSH 60 / 60 / 5 mm with a minimum length 10 % longer than the width of the sheet;
 six channels 40 / 35 / 5 mm, with a length 10 % longer than the width of the sheet;
 three supports;
 three square bars 20 / 20 mm x 40 mm;
 I-beam HEA 140 x 1 500 mm;
 hydraulic or electro-mechanical cylinder capable of supplying a force of 10 kN;
 force receiver, mounted between I-beam and the cylinder;
 one electronic elongation device accurate to 0,01 mm with a fixed disk of 20 mm on the top;
 precision metal ruler with 0,5 mm divisions.
7.2.1.2 Procedure
7.2.1.2.1 Set up
With reference to Figure 8, the four square tubes are placed on the bench, adjusted to the span of 620 mm
and properly fixed to the bench. The corrugated bitumen sheet is placed on the square tubes and adjusted
centrally under the cylinder. In the case of an irregular profile, the nearest bottom of a corrugation is always at
the centre of the cylinder.
The six channels with the three supports are placed loose on the sheet and adjusted. In the middle of each
support a square bar is placed as a joint for the I-beam.
The total mass of the preload shall be equal to (60 ± 5) kg.
The elongation device is mounted rigid and vertical underneath the test piece. The position shall be exactly in
the middle between the two square tubes and at the bottom of a corrugation directly central under the cylinder.
After applying the six channels, three supports, I-beam, the force receiver and the elongation device, ensure
that there is no gap between the corrugated bitumen sheet and the two central square tubes. If a gap exists,
the corrugated bitumen sheet is not suitable for this test and shall be changed.
Once this check has been made, the electronic elongation device is set to zero.
7.2.1.2.2 Area of the load
The width w of the corrugated bitumen sheet is measured before the test according to 7.1.2. The length shall
be three times the distance between the square tubes, i.e. 3 x 620 mm = 1 860 mm.
The area over which the load is distributed shall be calculated as:
6 2
load area = w x 1 860 / 1 x 10 [m ]

Figure 8 — Bending under downward load
7.2.1.2.3 Test execution
The speed of the cylinder shall be between 1 to 3 mm/min.
Force and elongation shall be recorded simultaneously, until the deflection is greater than 4,0 mm.
The test is carried out on five different corrugated bitumen sheets.
7.2.1.3 Results
Five graphs (one for each sheet) giving deflection as a function of force shall be produced. The force at an
elongation of 3,1 mm shall be read off these graphs. The uniform load for each sheet shall be calculated
using:
uniform load = force / load area [N/m ]
The result is the arithmetic mean of the five corrugated bitumen sheets, expressed to the nearest 10 N/m .
7.2.2 Impact strength
7.2.2.1 Equipment
The equipment is shown in Figure 9 and comprises:
 strong horizontal bench with a minimum height of 700 mm;

 eight clamps;
 sphero-conical bag (ISO 7892) filled with sand having a total mass of 40 kg;
 release hook.
7.2.2.2 Procedure
The corrugated bitumen sheet shall be laid on the construction and fixed by the four wooden supports, using
clamps or screws without compressing the height of the sheet.
The sack shall be positioned to have a height of fall between the bottom of the sack and the crown of the
corrugations, at mid-point between two supports and at the centre of the sheet, depending on the category.
The sack shall be released without any initial momentum.
The test is carried out on five different corrugated bitumen sheets.
7.2.2.3 Results
The sheet shall resist the impact of the bag. The test is deemed to have failed if the sack passes completely
through the sheet.
For the test to be passed, all five corrugated bitumen sheet shall pass.

The frame shall be placed around the test piece and the edges between test piece and the wall of the frame
shall be sealed watertight.
Demineralised water shall be poured into this container to a height of 100 mm above the crown of the
corrugation. The temperature of the water shall be (23 ± 2) °C.
The resulting test specimen shall be left for (48 ± 2) h in laboratory conditions, temperature (23 ± 3) °C, after
which the underside of the test piece shall be examined to see if there is any water penetration.
The test is carried out on one sample.

NOTE Three corrugations when the product includes a flat area.

7.3.1.3 Results
The test shall be judged to have passed or failed using visual assessment.
7.3.2 Proportion of bitumen
7.3.2.1 Equipment
The equipment necessary consists of a bitumen extractor apparatus (e.g. Kumagawa or Soxhlet) and a drying
cabinet. Methylene chloride, Trichloroethylene or Toluene are also required.
7.3.2.2 Procedure
The test pieces shall be put into the drying cabinet at least for 48 h at 70 °C. The test pieces are then weighed
to the nearest 0,01 g, this being the mass before extraction.
The test pieces shall then be placed into the hot extraction apparatus, and extraction shall continue until the
solvent remains clear.
The test pieces shall then be removed and the solvent allowed to evaporate under a ventilated hood.
When the solvent has evaporated, the test pieces are put into the drying cabinet for at least for 12 h at 105 °C.
The test pieces are then weighed to the nearest 0,01 g, this being the mass after extraction.
The test is carried out on three different samples.
7.3.2.3 Results
The bitumen content is calculated using:
content = [(mass before extraction – mass after extraction) / mass before extraction] x 100 [%].
The test is passed when all three tested samples meet the requirement.
7.3.3 Mass
7.3.3.1 Equipment
The equipment consists of a balance with a precision of ± 10 g.
7.3.3.2 Procedure
The total mass of each corrugated bitumen sheet shall be divided by the length (7.1.1) and width (7.1.2) of the
sheet.
The test is carried out on five different corrugated bitumen sheets.
7.3.3.3 Results
The result shall be the arithmetic mean of all five tested corrugated bitumen sheets, expressed to the nearest
0,02 kg/m .
7.3.4 Homogeneity of the product
7.3.4.1 Equipment
The equipment consists of a cutter.
7.3.4.2 Procedure
Each test piece shall be peeled by hand (or with the help of a cutter) so as to reveal the largest possible torn
surface (see Figure 12).
Each surface shall be checked to see if there is any area without bitumen larger than 1 cm .
The test is carried out on twelve samples.
7.3.4.3 Results
The test is passed if, for all twelve samples, no surface contains any area without bitumen larger than 1 cm .

7.3.5 Water absorption
7.3.5.1 Equipment
The equipment consists of a water bath, a drying cabinet and a balance. Demineralised water is also required.
7.3.5.2 Procedure
The test pieces shall be put into the drying cabinet for at least 48 h at 70 °C until their mass becomes constant.
The test pieces are then weighed to the nearest 0,01 g, this being the mass before absorption.
The test pieces shall then be placed horizontally in a container of demineralised water, without protection of
the cut surfaces. The temperature of the water shall be (23 ± 2) °C and its level shall be 100 mm above the
crown of the corrugations. The test pieces shall not touch each other.
After (24 ± 1) h, the test pieces shall be removed from the water and their surfaces wiped to remove any drops
of water. The test pieces are then weighed to the nearest 0,01 g, this being the mass after absorption.
The test is carried out on three samples.
7.3.5.3 Results
The water absorption is calculated using:
absorption = [(mass after absorption – mass before absorption)/mass before absorption] x 100 [%].
The test is passed when all three tested samples meet the requirement.
7.4 Durability
7.4.1 Tearing strength after freeze/thaw ageing
7.4.1.1 Procedure
First the frost resistance conditioning procedure (7.4.4) shall be performed on each test piece. After the last
cycle, the test pieces shall be stored for 24 h at laboratory conditions and then the tearing strength test (7.2.3)
shall be performed.
The test is carried out on five samples.
7.4.1.2 Results
The result is the mean of the five measurements, expressed to the nearest Newton.
7.4.2 Water impermeability after freeze/thaw ageing
7.4.2.1 Procedure
First the frost resistance conditioning procedure (7.4.4) shall be performed on the test piece. After the last
cycle, the test pieces shall be stored for at least 24 h at laboratory conditions and then the water
impermeability test (7.3.1) shall be performed. After (48 ± 2) h the underside of the test piece shall be
examined to see if there is any water penetration.
The test is carried out on one sample.
