Fibre-cement products - Determination of pull through and shear resistance and bending strength calculations - Part 2: Profiled sheets

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.

Faserzementprodukte - Bestimmung des Durchzugs- und Querkraftwiderstandes und der Biegefestigkeit - Teil 2: Wellplatten

Dieses Dokument legt Verfahren für die Prüfung des Durchzugs- (Zug /Stauchungsprüfung für Befestigungsmittel durch die Platten) und Querkraftwiderstands von Faserzement-Wellplatten nach EN 494 fest. Die Ergebnisse sind nur auf das Faserzementprodukt anwendbar, nicht auf die gesamte Befestigungsbaugruppe.
Es gilt nur für Produkte im Auslieferungszustand.
Der Anwendungsbereich für den Durchzugswiderstand ist in 7.6 festgelegt.
Der Anwendungsbereich für den Querkraftwiderstand ist in 8.6 festgelegt.
ANMERKUNG   Für die Zwecke des Designs von Faserzement-Wellplatten in der endgültigen Anwendung liegen Durchzug und Versagen der Befestigungen oder der Unterkonstruktion als Gründe für das Versagen nicht im Anwendungsbereich dieser Norm. Sie könnten entscheidend werden und müssen nach den relevanten Designnormen für Befestigungen (zum Beispiel Eurocode 2 für Stahl , Eurocode 5 für Holz  und Eurocode 9 für Aluminiumunterkonstruktionen) geprüft und mit den Ergebnissen für den Durchzugs- und Querkraftwiderstand verglichen werden.

Produits en fibres-ciment - Détermination des calculs de résistance au déboutonnage, au cisaillement et à la flexion - Partie 2 : Plaques profilées

Le présent document spécifie des méthodes d'essai de la résistance au déboutonnage (essai de traction/compression pour les éléments de fixation qui traversent les plaques) et au cisaillement des plaques profilées en fibres-ciment selon l'EN 494. Les résultats ne sont applicables qu'au produit en fibres-ciment, et non à l'assemblage de fixation complet.
Le présent document ne s'applique qu'aux produits dans l'état où ils sont livrés.
Le domaine d'application de la résistance au déboutonnage est défini au 7.6.
Le domaine d'application de la résistance au cisaillement est défini au 8.6.
NOTE   Aux fins de la conception des plaques profilées en fibres-ciment dans l'application finale, les ruptures de type « arrachement » et « rupture des fixations ou de la sous-structure » sont exclues du domaine d'application de la présente norme. Elles peuvent devenir décisives et doivent être déterminées par un essai ou calculées selon les normes de conception adéquates pour les fixations (par exemple, Eurocode 3 pour l'acier, Eurocode 5 et Eurocode 9 pour les sous-structures en aluminium) et comparées aux résultats des essais de résistance au déboutonnage et au cisaillement.

European foreword

This document (prEN 17468-2:2020) 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 document is currently submitted to the CEN Enquiry.

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.

This is a product 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 the

assembly as a whole in relation to the environment and conditions of use.

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 sheets shall be pre-drilled allowing a clearance hole around the fastener as recommended by the

sheeting manufacturer (minimum 1mm 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 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 sheets shall be pre-drilled allowing a clearance hole around the fastener as recommended by the

sheeting manufacturer (minimum 1 mm clearance). The sheets can be pre-drilled before or after

conditioning.

The minimum edge distances lmin,long and lmin,perp should be specified by the manufacturer.

7 Test method for the determination of pull through resistance of fibre cement
profiled sheets
7.1 Principle

The pull through resistance is determined by the maximum load Fax (in N) required to pull the fastener

through the test sheet.
7.2 Test equipment
7.2.1 Tensile testing machine

The test rig shall be essentially composed of a vertical-uniaxial class-1 tensile testing machine as per

EN ISO 7500-1 with force capacity appropriate to delivering the loading required (for example: 10 kN),

featuring the following main components:
— an upper test-frame part fitted with a specimen-holding device;
— a lower test-frame part fitted with a second specimen-holding device.

Either or both parts shall, by virtue of design, enable alignment of the fixtures and the vector of loading.

NOTE The test device simulates a fibre-cement profiled sheeting-to-purlin roofing fixture, as illustrated in Figure 1,

or by changing the configuration can also be used to simulate sheets fixed through the valley corrugations for use

as wall cladding.
---------------------- Page: 10 ----------------------
oSIST prEN 17468-2:2020
prEN 17468-2:2020 (E)

The fastener shall be held in the upper-frame grip as illustrated in the schematic diagrams given in

Figures 2 and 3.

If the length or geometry of the fastener means it cannot be held directly in the upper-frame grip, then a

mechanical system that fixes into the upper-frame grip should be used (see Figures 2 and 3).
