Overview

The prEN 544 rev standard, developed by CEN, provides a comprehensive product specification and test methods for bitumen shingles reinforced with mineral and/or synthetic materials. This standard focuses on the properties and performance of finished bitumen shingles before they are installed on pitched roofs or used for wall cladding. Importantly, prEN 544 rev addresses material characteristics, test procedures, marking, labelling, and the assessment and verification of constancy of performance (AVCP).

This standard excludes design requirements, installation techniques, and overall roof system performance, concentrating strictly on the product specifications and testing to ensure quality and durability of bitumen shingles within the specified application scope.

Key Topics

• Material Composition
  Includes bitumen shingles reinforced with mineral, synthetic, or mixed reinforcements. It specifies bitumen mass minimums of 1300 g/m² for monolayer shingles and 1500 g/m² for multilayer shingles, where multilayer shingles require uniform reinforcement and coating per layer.

• Geometrical Properties
  Defines maximum and minimum dimensions for shingles, such as a maximum width of 1200 mm and minimum height of 250 mm, with strict tolerances of ±3 mm.

• Mechanical Properties
  Detailed requirements for tensile strength and nail shank tear resistance, critical for shingles intended for nailed roofing applications. Tensile strength minimums include 600 N/50 mm in the width/fabrication direction and 400 N/50 mm perpendicular to it, with nail tear resistance exceeding 100 N.

• Durability Tests
  Standards for resistance to UV radiation and blistering ensure long-term performance. UV resistance testing guarantees shingles do not crack or fissure under simulated environmental exposure.

• Fire Performance
  Fire classification tests follow EN 13501-1 and EN 13501-5, providing evaluation criteria for roofs subject to external fire exposure.

• Marking and Labelling Requirements
  The standard includes clear rules for product designation, marking, and labelling so that manufacturers and users can identify and verify product characteristics and compliance effectively.

• Assessment and Verification of Constancy of Performance (AVCP)
  Specifies factory production control requirements and type testing frequencies ensuring consistent product quality.

Applications

• Pitched Roofing Covers
  Bitumen shingles manufactured under prEN 544 rev are designed for durable weatherproof coverage on inclined roofs, ensuring watertightness through overlapping and adhesive systems per manufacturer instructions.

• Wall Cladding
  The standard also applies to shingles intended as protective and decorative cladding for pitched or vertical surfaces.

• Building Construction and Renovation
  Ideal for architects, builders, roofing contractors, and manufacturers who require detailed product performance standards to meet regulatory and quality assurance demands in European markets.

• Quality Control and Certification
  This document assists manufacturers in establishing production processes compliant with European norms and facilitates certification processes for construction materials under the Construction Products Regulation (EU No. 305/2011).

All sampling shall be in accordance with Clause 5.
6.2 Mass of bitumen
6.2.1 General
Two different tests methods are available for the determination of the mass of bitumen:
— Extraction method,
— Calcination method.
prEN 544:2020 (E)
6.2.2 Extraction method
6.2.2.1 Test conditions
Temperature : (23 ± 2) °C,
relative humidity : (50 ± 20) % RH,
test piece conditioning : minimum 2 h.
6.2.2.2 Equipment
— Soxhlet extractor or similar,
— balance accurate to ± 0,01 g,
— drying oven at controlled temperature (105 ± 2) °C,
— trichloroethylene, perchloroethylene, methylene chloride, toluene or xylene solvents.
6.2.2.3 Procedure
The test piece is placed in a container (the test piece may be cut into strips provided that any fragment
of material which become detached are recovered and placed in the container) which has been
previously dried and weighed (M ) and provided with a cotton plug or other appropriate closure.
Reweigh the container with the test piece and the closure (M ) and place in the extractor. Arrange so
that the opening fitted with the closure projects beyond the level of the solvent.
Continue the extraction until the solvent is colourless in the extractor.
Remove the container for drying, initially in air (30 min), then in a drying oven controlled at a
temperature of (105 ± 2) °C until a constant mass for the sample is achieved (constant mass means that
the difference between two consecutive weightings is less than or equal to 0,05 g).
Weigh the container fitted with the closure (M ).
Repeat this procedure for the two remaining test pieces.
6.2.2.4 Expression of results
In the extraction test, the following masses are determined for each test piece:
— test piece M – M ,
2 1
— mass of bitumen M – M .
2 3
For each test piece, express the final result in grams per square metre. Calculate the arithmetic mean
value of the test specimens (three for monolayer and two for multilayer).
6.2.3 Calcination method
6.2.3.1 Test conditions
Test piece conditioning : 2 h.
prEN 544:2020 (E)
6.2.3.2 Equipment
— Calcination oven at controlled temperature (575 ± 25) °C,
— balance accurate to ± 0,01 g,
6.2.3.3 Procedure
The test piece is placed in a container which has previously dried. Put the test piece in the container and

7 Assessment and verification of constancy of performance - AVCP
7.1 General
The compliance of bitumen shingles with mineral and/or synthetic reinforcements with the
requirements of this standard and with the declared values 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 product.
7.2 Type testing
7.2.1 General
All the performances related to characteristics included in this standard other than the essential
characteristic may be determined when the manufacturer claims compliance with them, unless the
standard gives provisions for declaring them without performing tests (e.g. use of previously existing
data, CWFT and conventionally accepted performance).
For the purposes of testing, 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 that same characteristics for all products within that same family
Tests 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: Products may be in different families for different characteristics.
Note: Reference to the test 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 performances:
— at the beginning of the production of a new or modified bitumen shingles with mineral and/or
synthetic reinforcements (unless a member of the same family), 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 bitumen
shingles with mineral and/or synthetic reinforcements design, in the raw material or in the supplier of
the components, or in the production process (subject to the definition of a family), which would affect
significantly one or more of the characteristics.
Where components are used whose characteristics have already been determined, by the component
manufacturer, on the basis of compliance with other product standards, these characteristics need not
be re-assessed. The specifications of these components shall be documented, as shall be included in the
inspection scheme for ensuring their compliance.
Products marked in accordance with appropriate harmonized European specifications may be
presumed to have the performances stated with the marking, although this does not replace the
prEN 544:2020 (E)
responsibility on the bitumen shingles with mineral and/or synthetic reinforcements designer to
ensure that the bitumen shingles with mineral and/or synthetic reinforcements as a whole is correctly
designed and its component products have the necessary performance values to meet the design.
7.2.2 Test samples, testing and compliance criteria
The number of samples of bitumen shingles with mineral and/or synthetic reinforcements to be
tested/assessed shall be in accordance with Table 2.

Indirect control, e.g. of raw materials and the production process, with a frequency sufficient to ensure that
the results from initial type testing remains representative for current production. This frequency shall be given
in the manufacturer’s FPC system documentation.
b
In the case where a manufacturer is continuously producing numerous different shingles which contain the
same carrier (type and mass) and the same type of coating, the frequency of these tests which relate essentially
to the carrier, may be considered on the total number of these different shingles.
c
In the case where a manufacturer is continuously producing numerous differently reinforced shingles
and/or shingles which differ only by the presence of incorporated protection, whilst using the same type of
coating and having a similar nominal thickness, the frequency for these tests, which relate essentially to the
type of coating, may be considered on the total number of these different shingles.
7.2.3 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
bitumen shingles with mineral and/or synthetic reinforcements to which they relate.
7.2.4 Shared other party results
It is in principle applicable to all systems of assessment and evaluation of constancy of performance.
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), hereafter
prEN 544:2020 (E)
called “other party ITT results”, 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:
— the results are known to be valid for products with the same characteristics relevant for
performance;
— in addition to any information essential for confirming that the product has such same
characteristics, the other party who has carried out the 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;
— the manufacturer using other party results accepts remaining responsible for the product being in
compliance with the declared performances;
— he 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
— he 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.
7.3 Factory production control (FPC)
7.3.1 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 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.
7.3.2 Requirements
7.3.2.1 General
The manufacturer is responsible for organizing the effective implementation of the FPC system. 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 needs to
prEN 544:2020 (E)
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 product constancy of performance 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 shoul
