Overview

The draft European Standard kSIST FprEN 13707:2018:2017 titled "Flexible sheets for waterproofing - Reinforced bitumen sheets for roof waterproofing - Definitions and characteristics" is prepared by CEN Technical Committee CEN/TC 254. This standard specifies comprehensive definitions, criteria, and performance characteristics for flexible reinforced bitumen sheets intended for roofing applications. It covers various usages including top layers, intermediate layers, and underlays in roofing systems.

This standard is essential for manufacturers, architects, contractors, and quality assessors working with bituminous roofing materials, ensuring consistent quality, safety, and durability across Europe. It also supports compliance with EU Construction Product Regulation (EU Regulation 305/2011).

Key Topics

• Scope and Definitions: The standard defines key terms such as waterproofing, roofing sheet, carrier, backing, surfacing, and roofing system. It clarifies the intended application of reinforced bitumen sheets in roofing including those exposed to traffic or roofs with special uses like parking or gardens.

• Product Characteristics: Detailed technical specifications cover:

  • Visible defects, dimensions, mass per unit area
  • Watertightness and resistance to water effects
  • Fire performance and classification under CPR (Construction Products Regulation)
  • Resistance to hail impact, root penetration, tearing, and static loading
  • Performance under temperature extremes (low and elevated temperatures) including flexibility and dimensional stability
  • Tensile properties and joint strength to assure mechanical durability
  • Aging and artificial weathering to evaluate long-term performance
  • Adhesion of granules and surface treatments for durability and protection

• Assessment and Verification: The document outlines factory production control (FPC) procedures and type testing, including sampling, compliance criteria, continuous surveillance, and management of modifications.

• Normative References: Lists related EN standards for test methods concerning dimensional stability, fire resistance, water tightness, tensile and tear resistance, among others.

Applications

kSIST FprEN 13707:2018:2017 applies primarily to:

• Roof waterproofing: Ensuring high-performance flexible bituminous sheets are used on flat, pitched, or vertical roofs.
• Multilayer roofing systems: Defines requirements for sheets used as top layers, intermediate layers, or underlays within composite roofing structures.

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.
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.
oSIST prEN 13707:2017
prEN 13707:2017 (E)
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
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
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
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
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.

oSIST prEN 13707:2017
prEN 13707:2017 (E)
In the case of sheets with the same bituminous compound on both sides and where the reinforcement is
placed in the cross section visually closer to the upper surface, the test shall be performed on the
bottom face only.
If the upper surface is covered with a non- woven (e.g. tissue, fleece, etc.) or metal facing the test shall
be performed on the bottom side only.
If the sheet on the upper surface is covered with permanent light surface protection and where the
reinforcement is placed in the cross section visually closer to the upper surface the test shall be
performed on the bottom side only.
5.2.18 Flow resistance at elevated temperature
The flow resistance at elevated temperature shall be determined in accordance with EN 1110 and shall
be greater than or equal to the manufacturer's limiting value.
5.2.19 Artificial ageing behaviour
5.2.19.1 Top layers and single layers with permanent light surface protection
In order to verify the artificial ageing behaviour of the product, characteristics shall be determined
before and after exposure in accordance with EN 1296 for a period of 12 weeks. The relevant
characteristics are the flexibility at low temperature or the flow resistance at elevated temperature. The
flexibility at low temperature shall be determined in accordance with EN 1109 (see 5.2.17) and the
results shall lie within the declared tolerance of the manufacturer’s declared value. The flow resistance
at elevated temperature shall be determined in accordance with EN 1110 (see 5.2.18) and the results
shall lie within the declared tolerance of the manufacturer’s declared value.
The purpose of testing in accordance with EN 1296 is to characterize the long-term thermal stability of
elastomeric or plastomeric bitumen. The test does not give results corresponding to the service
conditions in practice. Results should only be used to compare products of similar thickness,
construction and composition, and they cannot be used for general durability classification. The chosen
exposure duration for artificial ageing in accordance to EN 1296 has no relevance to a real product
lifetime.
NOTE When reinforced oxidized bitumen roofing sheets are tested as described in this subclause they
become brittle and have poor low temperature flexibility. However, experience shows that when they are
reinforced and protected properly, they perform satisfactorily in the long term.
5.2.19.2 Top layers and single layers without surface protection
Materials used as top layers without permanent surface protection (e.g. mineral granules, metal foil,
gravel or any additional protection) shall be tested in addition with EN 1296 according to 5.2.19.1 by
the method for artificial ageing by long-term exposure to the combination of UV radiation, elevated
temperature and water in accordance with EN 1297 for a period of 1 000 h UV exposure and evaluated
for visual defects in accordance with EN 1850-1.
5.2.19.3 Top layers with permanent heavy surface protection, underlayers and intermediate
layers
Top layers with permanent heavy surface protection (e.g. with loose-fill gravel), underlayers and
intermediate layers are not subject to testing of artificial ageing behaviour.
5.2.20 Adhesion of granules
Where the top surface of the sheet is protected with incorporated mineral granules the granule
adhesion shall be determined in accordance with EN 12039 and the results shall lie within the declared
tolerance of the manufacturer's declared value and shall not exceed 30 % by mass of granules.

5.3 Dangerous substances
Where required the release of dangerous substances shall be declared.
6 Assessment and verification of the constancy of performance – AVCP
6.1 General
The compliance of reinforced bitumen sheets for roof waterproofing with the requirements of this
standard and with the performances declared by the manufacturer in the DoP shall be demonstrated
by:
— determination of the product type;
— factory production control by the manufacturer, including product assessment.
The manufacturer shall always retain the overall control and shall have the necessary means to take
responsibility for the conformity of the product with its declared performance(s).
6.2 Type testing
6.2.1 General
All performances related to characteristics included in this standard shall be determined when the
manufacturer intends to declare the respective performances unless the standard gives provisions for
declaring them without performing tests (e.g. use of previously existing data, CWFT and conventionally
accepted performance).
Assessment previously performed in accordance with the provisions of this standard, may be taken into
account provided that they were made to the same or a more rigorous test method, under the same
AVCP system on the same product or products of similar design, construction and functionality, such
that the results are applicable to the product in question.
NOTE 1 Same AVCP system means testing by an independent third party [only for products covered by system
1+, 1 and 3], under the responsibility of a notified product certification body [only for products covered by system
1+ and 1].
For the purposes of assessment, the manufacturer's products may be grouped into families, where it is
considered that the results for one or more characteristics from any one product within the family are
representative for the same characteristics for all products within that same family.
NOTE 2 Products may be grouped in different families for different characteristics.
NOTE 3 Reference to the assessment method standards should be made to allow the selection of a suitable
representative sample.
In addition, the determination of the product type shall be performed for all characteristics included in
the standard for which the manufacturer declares the performance (see Table D.1):
— at the beginning of the production of a new or modified product (reinforced bitumen sheet) for roof
waterproofing (unless a member of the same product range), or
— at the beginning of a new or modified method of production (where this may affect the stated
properties); or
— they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the
reinforced bitumen sheets for roof waterproofing, in the raw material or in the supplier of the
oSIST prEN 13707:2017
prEN 13707:2017 (E)
components, or in the method of production (subject to the definition of a family), which would
affect significantly one or more of the characteristics of the product.
Where components are used whose characteristics have already been determined, by the component
manufacturer, on the basis of assessment methods of other product standards, these characteristics
need not be re-assessed. The specifications of these components shall be documented.
Products bearing regulatory marking in accordance with appropriate harmonized European
specifications may be presumed to have the performances declared in the DoP, although this does not
replace the responsibility on the reinforced bitumen sheets for roof waterproofing manufacturer to
ensure that the reinforced bitumen sheets for roof waterproofing as a whole is correctly manufactured
and its component products have the declared performance values.
6.2.2 Test samples, testing and compliance criteria
The number of samples of reinforced bitumen sheets for roof waterproofing to be tested/assessed shall
be in accordance with EN 13416.
6.2.3 Test reports
The results of the determination of the product type shall be documented in test reports. All test reports
shall be retained by the manufacturer for at least 10 years after the last date of production of the
reinforced bitumen sheets for roof waterproofing to which they relate.
6.2.4 Shared other party results
A manufacturer may use the results of the product type determination obtained by someone else (e.g.
by another manufacturer, as a common service to manufacturers, or by a product developer), to justify
his own declaration of performance regarding a product that is manufactured according to the same
design (e.g. dimensions) and with raw materials, constituents and manufacturing methods of the same
kind, provided that:
a) the results are known to be valid for products with the same essential characteristics relevant for
the product performance;
b) in addition to any information essential for confirming that the product has such same
performances related to specific essential characteristics, the other party who has carried out the
1)
determination of the product type concerned or has had it carried out, has expressly accepted to
transmit to the manufacturer the results and the test report to be used for the latter’s product type
determination, as well as information regarding production facilities and the production control
process that can be taken into account for FPC;
c) the manufacturer using other party results accepts to remain responsible for the product having
the declared performances and he also:
1) ensures that the product has the same characteristics relevant for performance as the one that
has been subjected to the determination of the product type, and that there are no significant
differences with regard to production facilities and the production control process compared
to that used for the product that was subjected to the determination of the product type; and
2) keeps available a copy of the determination of the product type report that also contains the
information needed for verifying that the product is manufactured according to the same
design and with raw materials, constituents and manufacturing methods of the same kind.

1) The formulation of such an agreement can be done by licence, contract, or any other type of written consent.

6.3 Factory production control (FPC)
6.3.1 General
The manufacturer shall establish, document and maintain an FPC system to ensure that the products
placed on the market comply with the declared performance of the essential characteristics.
The FPC system shall consist of procedures, regular inspections and tests and/or assessments and the
use of the results to control raw and other incoming materials or components, equipment, the
production process and the product.
All the elements, requirements and provisions adopted by the manufacturer shall be documented in a
systematic manner in the form of written policies and procedures.
This factory production control system documentation shall ensure a common understanding of the
evaluation of the constancy of performance and enable the achievement of the required product
performances and the effective operation of the production control system to be checked. Factory
production control therefore brings together operational techniques and all measures allowing
maintenance and control of the compliance of the product with the declared performances of the
essential characteristics.
In case the manufacturer has used shared or cascading product type results, the FPC shall also include
the appropriate documentation as foreseen in 6.2.4 and 6.2.5.
6.3.2 Requirements
6.3.2.1 General
The manufacturer is responsible for organizing the effective implementation of the FPC system in line
with the content of this product standard. Tasks and responsibilities in the production control
organization shall be documented and this documentation shall be kept up-to-date.
The responsibility, authority and the relationship between personnel that manages, performs or verifies
work affecting product constancy, shall be defined. This applies in particular to personnel that need to
initiate actions preventing product non-constancies from occurring, actions in case of non-constancies
and to identify and register product constancy problems.
Personnel performing work affecting the constancy of performance of the product shall be competent
on the basis of appropriate education, training, skills and experience for which records shall be
maintained.
In each factory the manufacturer may delegate the action to a person having the necessary authority to:
— identify procedures to demonstrate constancy of performance of the product at appropriate stages;
— identify and record any instance of non-constancy;
— identify procedures to correct instances of non-constancy.
The manufacturer shall draw up and keep up-to-date documents defining the factory production
control. The manufacturer's documentation and procedures should be appropriate to the product and
manufacturing process. The FPC system should achieve an appropriate level of confidence in the
constancy of performance of the product. This involves:
a) the preparation of documented procedures and instructions relating to factory production control
operations, in accordance with the requirements of the technical specification to which reference is
made;
b) the effective implementation of these procedures and instructions;
oSIST prEN 13707:2017
prEN 13707:2017 (E)
c) the recording of these operations and their results;
d) the use of these results to correct any deviations, repair the effects of such deviations, treat any
resulting instances of non-conformity and, if necessary, revise the FPC to rectify the cause of non-
constancy of performance.
Where subcontracting takes place, the manufacturer shall retain the overall control of the product and
ensure that he receives all the information that is necessary to fulfill his responsibilities according to
this European standard.
