Overview

EN 17468-2:2022 - "Fibre‑cement products - Determination of pull through and shear resistance and bending strength calculations - Part 2: Profiled sheets" is a CEN testing standard for fibre‑cement profiled sheets (as defined in EN 494). It specifies standardized laboratory test methods to determine:

• Pull through (tension/compression) resistance for fasteners through profiled sheets
• Shear resistance (both parallel and perpendicular to corrugations)
• Procedures and calculations for bending strength and bending modulus of elasticity

The standard applies only to products as delivered and to the fibre‑cement product itself - not to complete fixing assemblies or the performance of fixings and substructures.

Key topics and technical requirements

• Scope and applicability: Tests are limited to delivered profiled sheets; fields of application for pull through and shear resistance are defined in clauses 7.6 and 8.6.
• Sampling and type testing: Sampling methods and preparation of test specimens for pull through and shear tests are specified. Type testing is required for new products or when manufacturing changes may affect performance.
• Test equipment and procedures: Requirements for tensile/testing machines (calibrated per EN ISO 7500‑1), test set‑ups for shear tests, and details on fastener types used during testing.
• Result expression and reporting: Methods to express pull through and shear results, including average, characteristic and design values, and required test report content.
• Mechanical characteristics: Calculation procedures for bending strength (longitudinal and transverse) and bending modulus of elasticity; statistical treatment for characteristic values (reference to EN 1990 factors).
• Limitations: Failure modes such as pull‑out or breakage of fixings/substructure are not covered - designers must consult relevant fixings/substructure standards.

Practical applications

• Provide standardized performance data for manufacturers to declare mechanical properties of fibre‑cement profiled roofing and cladding sheets.
• Enable test laboratories to perform comparable pull‑through, shear and bending strength tests.
• Help specifiers, roof and façade designers, and building authorities assess product suitability and use test results as input for assembly design (note: fixing/substructure verification is separate).

Who should use this standard

• Fibre‑cement product manufacturers and R&D teams
• Accredited testing laboratories and certification bodies
• Structural and roofing engineers, façade consultants, and building regulators
• Procurement and quality control professionals in construction materials

Related standards

• EN 494 - Fibre‑cement profiled sheets (product specification and test methods)
• EN 17468‑1 - Part 1: Flat sheets (companion document)
• EN ISO 7500‑1 - Calibration of testing machines
• EN 1990 / Eurocodes (basis of structural design) and Eurocode standards for fixings/substructures (e.g., Eurocode 3, 5, 9)

EN 17468‑2:2022 is a testing standard (no classifications) that establishes harmonized methods for assessing the intrinsic mechanical resistance of profiled fibre‑cement sheets used in roofing and cladding systems.

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.

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.
