Foreword
This document (EN 494:2004) 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 IBN.
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text or by endorsement, at the latest by June 2005, and conflicting national standards shall be withdrawn at
the latest by June 2005.
This document supersedes EN 494:1994.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA and ZB, which is an integral part of this
document.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
A distinction has been made between product appraisal (type tests) and routine quality control requirements
(acceptance tests).
Attention is drawn to the need for observance of EU and/or EFTA Directives transposed into national legal
requirements restricting the use of certain materials and to the related marking and labelling requirements.
The performance of a roof or another building part constructed with these products depends not only on the
properties of the product as required by this document, but also on the design, construction and installation of
the components as a whole in relation to the environment and conditions of use.
1 Scope
This document specifies the technical requirements and establishes methods of control and test as well as
acceptance conditions for fibre-cement profiled sheets and their fibre-cement fittings for one or more of the
following uses:
 roofing,
 internal wall finishes,
 external wall and ceiling finishes.
For the purpose of this document fibre-cement profiled sheets are classified according to their height of
corrugation and their mechanical characteristics.
This document covers fibre-cement profiled sheets reinforced with fibres of different type as specified in 5.1.1,
with and without factory applied coating.
This document does not include calculations with regard to works, design requirements, installation
techniques, wind uplift or rain proofing of the installed sheets.
NOTE Some of these requirements can be applied to curved sheets, after agreement between manufacturer and
purchaser.

5 Product requirements
5.1 General
5.1.1 Composition
Fibre-cement profiled sheets and fittings shall consist essentially of cement or a calcium silicate formed by
chemical reaction of a siliceous and a calcareous material, reinforced by fibres. The cement shall comply with
EN 197-1 or with technical specifications relevant in the country of use.
Two types of fibre-reinforced cement profiled sheets and fittings are included in this document:
- Type AT (Asbestos Technology) for products the formulation of which contains chrysotile asbestos,
- Type NT (Non-asbestos Technology) for products reinforced by other fibres and not containing asbestos.
The reinforcing fibres shall be one or more of the following forms:
 discrete elements randomly dispersed;
 continuous strands or tapes;
 nets or webs.
Process aids, fillers and pigments which are compatible with the composite may be added.
5.1.2 Appearance and finish
The sheets may be left with their natural colour, or colouring matters may be added in the composition; they
may also receive adherent coloured or uncoloured coatings on their surface.
Variations of the surface appearance which do not impair the characteristics of the sheets as defined in this
document are permitted.
On exposure, the surface and/or its coating will be affected by weathering which may vary with site, location,
aspect, pitch of roof and duration of exposure. Any deterioration in this respect shall not detract from the
minimum mechanical and physical characteristics as specified in this document or from the function of the
sheet as a durable element.
Edges shall be straight and clean.
Sheets may have mitred or pre-mitred corner(s) and/or may be predrilled for fixing.
The fittings shall have a general appearance and finish compatible with the sheets with which they are to be
used. They may be supplied with holes for fixing.
5.2 Dimensions and tolerance

6 Evaluation of conformity
6.1 General
The conformity of products with the requirements of this document shall be demonstrated by:
 initial type testing; and
 factory production control by the manufacturer.
6.2 Type testing
6.2.1 General
Type tests shall be carried out on products as delivered. If several formats or sizes of the same nominal
thickness are being produced from the same composition and by the same production method, type tests only
need to be carried out on one size of each nominal thickness.
All characteristics listed in Table 6 shall be subject to initial type testing, except reaction to fire Class A1
without testing and external fire performance “deemed to satisfy” products.
Testing of mechanical characteristics is normally carried out with the upper face in compression. If required to
establish a relationship between upper and under face testing, where significant differences are expected or if
required for design purposes, the load shall be applied on the under face. Results obtained for under face
testing are not relevant for classification.
6.2.2 Initial type testing
Initial type testing shall be performed to demonstrate conformity to this document. Tests previously performed
in accordance with the provisions of this document (same product, same characteristic(s), test method,
sampling procedure, same attestation of conformity, etc.) may be taken into account. In addition initial type
testing shall be performed for the approval of a new product, or a fundamental change in formulation or
method of manufacture, the effects of which cannot be predicted on the basis of previous experience.
The results of all type tests shall be recorded and held by the manufacturer for at least 5 years.
6.2.3 Further type testing
Whenever a change occurs in the fibre-cement sheet design, the raw material or supplier of components, or
the production process, which would change significantly one or more of the characteristics, the type test shall
be performed for the appropriate characteristic(s).

6.3 Factory Production Control (FPC)
6.3.1 General
The manufacturer shall establish, document and maintain a FPC system to ensure that the products placed on
the market conform with the stated performance 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.
A manufacturer who has established a Quality Management System according to EN ISO 9001, is considered
to satisfy the above requirements.
The results of inspections, tests or assessments requiring action shall be recorded, as shall the action(s)
taken.
6.3.2 Acceptance tests
The specifications of acceptance tests apply to the product as delivered, but may be carried out at an earlier
stage of maturity.
Sampling from continuous production testing
 on the base sheet prior to coating,
 in conditions other than in Table 8,
is acceptable provided that it has been statistically established (see Annex C) that compliance with the
requirements given in Table 3 is ensured.
Acceptance tests can also be used to confirm that a batch of sheets or fittings conforms with the standard, e.g.
in conjunction with type tests or for receiving inspection.
The tests include the:
 measurement of dimensions - length, width and thickness (methods specified in 7.2.1);
 measurement of apparent density (method specified in 7.3.1, for sheets only);
 measurement of mechanical characteristics - bending strength (method specified in 7.3.2, for sheets only).
Each limit of specification, for the characteristics in Table 7, shall be subject to an AQL of 4%. The sampling
schemes provided in ISO 390, with an AQL of 4% and an inspection level S , ensure that for large batches
approximately 95% of the items fulfil the requirements.

6.3.3 Equipment
All weighing, measuring and testing equipment shall be calibrated and regularly inspected according to
documented procedures, frequencies and criteria.
6.3.4 Raw materials and components
The specification of all incoming raw materials and components shall be documented, as shall the inspection
scheme for ensuring conformity.
6.3.5 Product testing and evaluation
The manufacturer shall establish procedures to ensure that the stated values of all of the characteristics are
maintained.
6.3.6 Non-conforming products
Non-conforming product shall be separated and handled according to documented procedures.
6.4 Inspection of a consignment of finished products
Inspection of a consignment of finished products is not a requirement of this document but if, in special cases,
it is demanded by the customer, it may be carried out in accordance with Annex B and ISO 390.
