This document (EN 17468-2:2022) has been prepared by Technical Committee CEN/TC 128 “Roof
covering products for discontinuous laying and products for wall cladding”, the secretariat of which is
held by NBN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by September 2022, and conflicting national standards shall
be withdrawn at the latest by September 2022.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document is part 2 of the EN 17468 series and deals with profiled sheets, whereas part 1 deals with
flat sheets.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,

Introduction
Different fibre-cement profiled sheets on the market are assessed for pull through resistance.
Fibre-cement profiled sheets have been evaluated for pull through and shear resistance by a number of
test methods designed to simulate conditions of use.
The results from the different existing methods are not directly comparable.
This document establishes an agreed method for evaluation of the pull through resistance of fibre-cement
profiled sheet products, based on the experiences obtained over the last number of years in different
countries. The document is partly based on the French national standard NF P30-311.
This is a testing standard with no classifications, but this test procedure may be used by national
regulators to set classifications for roof and wall assemblies.
The performance of an assembly constructed with these products depends not only on the properties of
product as required by this document, but also on the design, construction and performance of an
assembly to be assessed by appropriate methods such as calculations or testing.
1 Scope
This document specifies test methods for pull through (tension/compression testing for fasteners
through the sheets) and shear resistance of fibre-cement profiled sheets according to EN 494. The results
are only applicable to the fibre-cement product and not to the complete fixing assembly.
It applies only to products as delivered.
The field of application for pull through resistance is defined in 7.6.
The field of application for shear resistance is defined in 8.6.
NOTE For design purposes of fibre-cement profiled sheets in the final application, the failure modes pull-out
and breaking of the fixings or substructure are not in the scope of this standard. They might become decisive and
need to be tested or calculated according to the relevant design standards for fixings (e.g. Eurocode 3 for steel,
Eurocode 5 for wood and Eurocode 9 for aluminium substructures) and compared with the results for pull-through
and shear resistance.

The test method is applicable to fibre-cement profiled sheets manufactured in accordance with EN 494.
5.2 Appearance and finish
The appearance and finish shall be evaluated as defined in EN 494.
6 Sampling procedure
6.1 Sampling method
Take an adequate number of full size sheets drawn at random from a consignment of sheets or, in the
case of continuous production, from a production batch. All test specimens used on the test assembly
shall be from the same consignment or production batch. The size of the batch is chosen by the
manufacturer up to a maximum of one week’s production.
6.2 Type testing
The pull through resistance and shear resistance tests, for fibre-cement profiled sheets, are type tests.
For continuous production the type test shall be repeated at least once every year.
6.3 Preparation of test specimens
6.3.1 Preparation of the test specimens for the pull through test
Cut 2 samples from a minimum of 10 profiled sheets to a length of (625 ± 5) mm and a width of
2 corrugations ± 5 mm. For each test, the 2 samples should be taken from the same sheet. For crown
fixings, the test specimens shall comprise one crown and two valleys, with the crown central in the width
of the test specimen. For valley fixings, the test specimen should comprise one valley and two crowns,
with the valley central in the width of the test specimen.
The specimens should be stored for 7 days ± 1 day in ambient laboratory conditions followed by 24 h
immersion in water.
The normal conditioning is 7 days at 23 °C / 50 % RH followed by 24 h under water, the same as the
conditioning for type testing breaking load and bending moment in accordance with EN 494. Other
conditions may be used provided that for design appropriate correction factors are introduced to
(Kappa wet) is used for calculation
recalculate the measured values to the wet conditioning. A factor κwet
of the design values (see 9.2.2 Formula (21)) in wet condition.
The sheets shall be pre-drilled allowing a clearance hole around the fastener as recommended by the
sheeting manufacturer (minimum 1 mm clearance) or, for tests on winged fasteners, directly using the
self-drilling fasteners. The sheets can be pre-drilled before or after conditioning.
6.3.2 Preparation of test specimens for the shear resistance test
Cut a minimum of 20 profiled sheets (10 for both directions) to a length of (300 ± 5) mm and a width of
3 corrugations with the cuts at the crown corrugations.
The specimens should be stored for 7 days ± 1 day in ambient laboratory conditions followed by 24 h
immersion in water.
The normal conditioning is 7 days at 23 °C / 50 % RH followed by 24 h under water, the same as the
conditioning for type testing breaking load and bending moment in accordance with EN 494. Other
conditions may be used provided that for design appropriate correction factors are introduced to
recalculate the measured values to the wet conditioning.
The sheets shall be pre-drilled allowing a clearance hole around the fastener as recommended by the
sheeting manufacturer or use self-drilling fasteners. The sheets can be pre-drilled before or after
conditioning.
The minimum edge distances (longitudinal and perpendicular) l and should be specified by
min,long lmin,perp
the manufacturer.
