5 Product characteristics
5.1 General
Where a tolerance is limited by this standard it does not have to be declared by the manufacturer.
When tested for purposes other than type testing or factory production control, the tests to determine
product characteristics indicated in this standard shall be started within one month of delivery from the
manufacturer.
NOTE This time period is chosen in order to limit the effect of inappropriate handling and storage after
delivery by people other than the manufacturer.
5.2 Characteristics
5.2.1 Visible defects
The product shall be free of visible defects, as determined in accordance with EN 1850-1.

---------------------- Page: 10 ----------------------
oSIST prEN 13707:2017
prEN 13707:2017 (E)
5.2.2 Dimensions, tolerances and mass per unit area
The length, width and straightness of the sheet shall be determined in accordance with EN 1848-1. The
length and width shall not be shorter than the manufacturer's limiting value. The maximum deviation
from straightness shall not exceed 20 mm per 10 m length or in proportion for other lengths (e.g.
10 mm per 5 m length).
Where a product is specified by mass per unit area, it shall be measured in accordance with EN 1849-1,
except that the sample shall be 100 mm × 100 mm, and the results shall lie within the declared
tolerance of the manufacturer's declared value.
Where a product is specified by thickness, it shall be measured in accordance with EN 1849-1 and the
results shall lie within the declared tolerance of the manufacturer's declared value.
Where sheets with incorporated mineral protection are specified by thickness, the measurement of
thickness may be carried out on the granule-free selvedge. This shall be declared in the report.
5.2.3 Water tightness
The water tightness shall be determined in accordance with EN 1928:2000 using method A or B at an
applied water pressure of 10 kPa (0,1 bar) and shall give a pass result.
5.2.4 Effects of water
Not specified.
NOTE Experience has shown that water has little or no effect upon the in-service performance of reinforced
bitumen sheets. See also Annex C.
5.2.5 Fire performance
5.2.5.1 External fire performance
5.2.5.1.1 Product
When there is a requirement on external fire performance for products, the external fire performance
shall be declared in accordance to EN 13501-5 and CEN/TS 1187.
For B (t1) classification the product might be tested by using a fixed test configuration as shown in
roof
Annex D.
NOTE 1 Classification of the external fire performance of the product is given in the Commission Decision
2001/671/EC as amended.
NOTE 2 Products intended to be fully covered in normal usage, see Commission Decision 2000/553/EC, are
considered to fulfil requirements for the performance characteristics 'external fire performance' without the need
for testing.
NOTE 3 Different roof systems can lead to different classifications.
5.2.5.1.2 System
When there is no requirement on external fire performance for products but only roof systems, no
external fire performance classification of the product is relevant.
5.2.5.2 Reaction to fire
Where required, the product shall be tested and classified in accordance with EN 13501-1:2002,
Table 1. When tested according to EN ISO 11925-2, the products shall be tested under conditions of
surface flame attack.

NOTE It is currently considered that the Euro classes Classification system at Classes D and above requires
investigation to determine its appropriateness to the products covered by this document (the SBI test may be
inappropriate for products covered by the standard). Pending results of such an investigation and discussions in
the Fire Regulators Group, products covered by this document are tested to EN ISO 11925-2. If and when new fire
test scenario and test methods are developed for the products, this document will be amended to refer to them.
Reaction to fire is by definition a product test, as distinct from Resistance to fire, which is a system test.
Therefore, it is considered important to provide guidance in order to reduce the number of tests
required.
According to EN ISO 11925-2, the test is required to be undertaken on the exposed surface without any
substrate, in one direction only, and the reinforcement shall be stated by the manufacturer as “organic”
or “inorganic”.
c) Test results from EN ISO 11925-2 for a product with a given reinforcement and a bituminous
compound having a certain percentage of organic content shall apply to the same product having a
lower organic content.
d) Test results from EN ISO 11925-2 for a product with a given organic reinforcement and a
bituminous compound shall apply to a product having the same bituminous compound and an
inorganic reinforcement.
e) Test results from EN ISO 11925-2 for a product with a given reinforcement and bituminous
2
compound, with a thickness of above 2 mm or a mass per unit area of above 2 kg/m , shall apply to
any product with the same type of reinforcement and the same type of bituminous compound but
2
lower thickness or mass per unit area, down to a limit of 2 mm or 2 kg/m respectively.
Test results from EN ISO 11925-2 for a product with a given reinforcement and bituminous compound
2
with a thickness or mass per unit area below 2 mm or 2kg/m , shall apply to any product with the same
type of reinforcement and the same type of bituminous compound but with higher thickness or mass
2
per unit area, up to a limit of 2 mm or 2 kg/m respectively.
5.2.6 Resistance to hail
Not specified.
NOTE Experience has shown that hail has little or no effect upon the in-service performance of reinforced
bitumen sheets.
5.2.7 Water tightness after stretching at low temperature
Where required, the water tightness after stretching at low temperature shall only be determined for
mechanically fastened single layer applications in accordance with EN 13897 and the results shall be
greater than or equal to the manufacturer's limiting value.
5.2.8 Joint strength
The peel resistance of joints shall only be determined for mechanically fastened single layer
applications in accordance with EN 12316-1 and the results shall lie within the declared tolerance of the
manufacturer's declared value.
The shear resistance of joints shall be determined for all single layer applications in accordance with
EN 12317-1 and the results shall lie within the declared tolerance of the manufacturer's declared value.

5.2.9 Water vapour properties
If necessary, the moisture resistance factor μ of reinforced bitumen sheets may be determined in
accordance with EN 1931. If the factor μ is not determined, a value of 20 000 may be used for
calculation purposes.
5.2.10 Tensile properties
The tensile properties shall be determined in accordance with EN 12311-1 and the results (for the
longitudinal and transverse directions) shall lie within the declared tolerance of the manufacturer's
declared value.
5.2.11 Resistance to impact
Where required, the resistance to impact shall be determined in accordance with EN 12691 and shall be
expressed as the maximum drop height of the puncturing tool in millimetres, which has not caused
leakage of the flexible sheet, which shall be greater than or equal to the manufacturer's limiting value.
Products shall be tested in accordance with EN 12691, method A.
Where subject to regulatory requirements or where the manufacturer wishes to make such a
declaration, products shall also be tested in accordance with EN 12691, method B.
The method(s) used shall be stated in the product data sheet.
5.2.12 Resistance to static loading
The resistance to static loading shall be determined in accordance with EN 12730:2001, method A and
shall be greater than or equal to the manufacturer's limiting value.
5.2.13 Resistance to tearing (nail shank)
The resistance to tearing (nail shank) shall be determined in accordance with EN 12310-1 and the
results shall lie within the declared tolerance of the manufacturer's declared value.
5.2.14 Resistance to root penetration
The resistance to root penetration shall be determined only for products used as root barriers in roof
gardens in accordance with EN 13948 and shall give a pass result.
5.2.15 Dimensional stability
The dimensional stability shall be determined in accordance with EN 1107-1 and shall be less than or
equal to the manufacturer's limiting value. This test shall only be carried o
