ISO 10904:2011

Fibre-cement corrugated sheets and fittings for roofing and cladding

ISO 10904:2011 specifies technical requirements and methods for the inspection and testing of straight short and long fibre-cement profiled sheets and their fibre-cement fittings designed to provide the weather-exposed surfaces on roofs and internal and external walls of buildings. Products covered by ISO 10904:2011 can be used for other purposes, provided they comply with the appropriate national or international application code or standard. Some of the requirements of ISO 10904:2011 can apply, after agreement between manufacturer and purchaser, to curved profiled sheets. The type tests described in ISO 10904:2011 are not intended to evaluate the performance of the coating in isolation (color fastness, adhesion, etc.). Specific performance requirements for coatings are referenced in other International Standards or national standards. ISO 10904:2011 does not apply to fibre-cement profiled sheets and fittings reinforced with asbestos fibres.

Overview

ISO 10904:2011 - Fibre‑cement corrugated sheets and fittings for roofing and cladding specifies technical requirements and test/inspection methods for straight short and long fibre‑cement profiled (corrugated) sheets and associated fibre‑cement fittings used as weather‑exposed surfaces on roofs and internal/external walls. The standard covers composition, manufacture, dimensional tolerances, physical performance and conformity assessment (type tests, acceptance tests and quality control). It excludes asbestos‑reinforced products and does not evaluate coating performance in isolation (coating properties are covered in other standards).

Key topics and technical requirements

• Scope and product definitions: classification of short (≤ 0.9 m) and long (> 0.9 m) sheets, profile dimensions (pitch, height), fittings and terminology.
• Material and composition: cement or calcium‑silicate matrices reinforced with cellulose, synthetic or glass fibres; permitted forms (discrete fibres, strands, nets).
• Manufacture & appearance: permitted forming and curing methods; requirements for as‑delivered condition and finish.
• Dimensional requirements: nominal dimensions, tolerances and geometrical testing procedures (see normative annexes).
• Mechanical performance: breaking load, bending moment at rupture and bending modulus measured by standardized bending tests; definitions and test methods are provided (annexes include test procedures).
• Physical properties and durability tests: apparent density, water permeability, freeze–thaw, heat‑rain, warm water and soak‑dry performance - each with normative test methods.
• Impact resistance & fire behaviour: references and requirements for impact testing and fire classification as applicable.
• Conformity & sampling: type testing, production quality control systems, consignment inspection and statistical sampling plans.
• Exclusions & coating note: coatings are not assessed in isolation; specific coating performance should reference separate international or national standards.

Practical applications

• Ensures consistent quality and safety for roofing and cladding made from fibre‑cement corrugated sheets.
• Guides manufacturers on production controls, test regimes and product labeling.
• Informs architects, specifiers and contractors on expected material properties for design, procurement and installation decisions.
• Provides test laboratories and certification bodies with standardized test methods and sampling procedures for performance verification.

Who should use ISO 10904:2011

• Fibre‑cement product manufacturers and R&D teams
• Quality control and testing laboratories

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10904 was prepared by Technical Committee ISO/TC 77, Products in fibre reinforced cement.
This first edition of ISO 10904 cancels and replaces ISO 9384:1991 and ISO 9933:1995, which have been
technically revised.

Introduction
The performance of a roof or another building part constructed with the products covered by this International
Standard depends not only on the properties of the products as required by this International Standard, but
also on the design, construction and installation of the components as a whole relative to the environment and
the conditions of use.
This International Standard does not include calculations with regard to works, design requirements,
installation techniques, wind uplift or rain proofing of the installed sheets.

INTERNATIONAL STANDARD ISO 10904:2011(E)

Fibre-cement corrugated sheets and fittings for roofing and
cladding
1 Scope
This International Standard specifies technical requirements and methods for the inspection and testing of
straight short and long fibre-cement profiled sheets and their fibre-cement fittings designed to provide the
weather-exposed surfaces on roofs and internal and external walls of buildings.
Products covered by this International Standard can be used for other purposes, provided they comply with
the appropriate national or international application code or standard.
Some of the requirements of this International Standard can apply, after agreement between manufacturer
and purchaser, to curved profiled sheets.
The type tests described in this International Standard are not intended to evaluate the performance of the
coating in isolation (colour-fastness, adhesion, etc.). Specific performance requirements for coatings are
referenced in other International Standards or national standards.
This International Standard does not apply to fibre-cement profiled sheets and fittings reinforced with asbestos
fibres.

3 Terms and definitions
For the purposes of this document, the following definitions apply.
3.1
profiled sheet
component whose cross-section consists of corrugations
NOTE 1 Examples are shown in Figure 1.
NOTE 2 The corrugations are defined by their pitch, a, and their height, h.

Key

3.2
side corrugation
corrugation at the extreme end(s) of a cross section normally having a different pitch and height, normally
used for side overlapping
3.3
acceptance test
test to establish whether a batch of products conforms to a specification
NOTE 1 The test is performed on samples drawn from continuous production or from a consignment.
NOTE 2 Test methods, specifications and limit values are specified in this International Standard. Sampling levels and
acceptance criteria are specified in 6.3.
NOTE 3 See ISO 390.
3.4
type test
test performed to demonstrate conformity with the requirements of this International Standard or for the
approval of a new product and/or when a fundamental change is made in formulation and/or method of
manufacture, the effects of which cannot be predicted on the basis of previous experience
NOTE The test is performed on the as-delivered product, but is not required for each production batch.
3.5
acceptable quality level
AQL
maximum percent defective (or maximum number of defects per 100 units) that can be considered satisfactory
as a long-term average quality level in a sampling plan
NOTE When a manufacturer's process satisfies a sampling scheme with an AQL of 4 %, this indicates that 96 % of
the inspected product exceeds the specification. This type of specification provides the consumer with a clearly defined
lower quality boundary; this does not occur if acceptance is based solely on the average value of the measured property.
Examples of sampling schemes can be found in ISO 390, ISO 2859-1 and ISO 3951-1.

5.2.2 According to thickness
The thickness of the sheets may be
⎯ either approximately constant throughout the width of the profile (type A sheets); see Figure 2 a); or
⎯ vary regularly between the valley and the crown for corrugated sheets or between the lower part and the
upper part of ribs for asymmetrical section sheets, in the same cross-section (type B sheets); see
Figure 2 b).
a) Constant thickness b) Variable thickness
Figure 2 — Profiled sheet
5.2.3 According to minimum breaking load in bending for long sheets
For sheets with a length greater than 0,9 m (long sheets), each category of sheet is subdivided into classes
according to the value of the minimum breaking load in bending; see Table 3.
5.2.4 According to minimum bending moment at rupture for long and short sheets
For long and short sheets, each category of sheet is subdivided into classes according to the value of the
minimum bending moment at rupture; see Table 4.
National standards may choose one or more classes depending on the local conditions in the area of use.
National standards may specify, in addition of the minimum breaking load (in newtons per metre width), the
unit flexural strength (in newtons per square millimetre) provided that the manufacturer defines the profile,
including the side corrugations, and consequently indicates how to calculate the moment of inertia for the
specific corrugated surface section.
5.3 Dimensions and tolerances on nominal dimensions
5.3.1 General
The manufacturer shall specify the nominal dimensions, shapes and configuration of the edges of the fibre-
cement profiled sheets.
Fittings shall have nominal dimensions and shapes determined by the manufacturer and appropriate to the
corresponding fibre-cement profiled sheets with which the fittings are used.

Mechanical and physical properties are normally determined on product as delivered. The results shall be
identified as applying to coated or uncoated material. Failure of the coating does not constitute
non-compliance of the product with this International Standard.
Testing of mechanical characteristics is performed 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.

The manufacturer's literature shall specify the minimum apparent density of the profiled sheets. When tested
in accordance with 7.3.4, using the method given in Annex F, the density shall not be less than the specified
value.
5.4.4 Water permeability
When tested for water permeability in accordance with 7.3.5, using the method given in Annex G, traces of
moisture may appear on the underface of the specimen, but in no instance shall there be any formation of
water drops.
NOTE Some national testing methods and performance requirements for the water permeability can differ from those
given in this International Standard.
5.4.5 Freeze-thaw performance
5.4.5.1 Long and short sheets
This test shall be carried out if local climatic conditions justify it or national standards specify it.
When freeze-thaw testing is required, profiled sheets are tested in accordance with 7.3.6, using the test
method given in Annex H. The ratio, R , of the lower versus the upper estimate mean values of the bending
L
moments for the exposed and unexposed specimens, determined at the 95 % confidence level after
100 freeze-thaw cycles, shall not be less than 0,70.
Any visible cracks, delamination or other visible alteration shall not be of such a degree as to affect the
performance in use.
5.4.5.2 Fittings
This test shall be carried out if local climatic conditions justify it or national standards specify it.
When freeze-thaw testing is required, fittings are tested in accordance with 7.3.7, using the test method given
in Annex H. Any visible cracks, delamination or other visible alteration after 100 freeze-thaw cycles shall not
be of such a degree as to affect the performance in use.
5.4.6 Heat-rain performance
When tested in accordance with 7.3.8, using the test method given in Annex I, after 50 heat-rain cycles, any
visible cracks, delamination or other defects in the sheets shall not be of such a degree as to affect their
performance in use. In case of doubt, a water-permeability test shall be performed on the sheet considered to
have the highest incidence of defects after heat-rain exposure. When a product has successfully passed this
water-permeability test, it shall be considered to comply with the requirement of heat-rain performance .
5.4.7 Warm water performance
When tested in accordance with 7.3.9 or 7.3.10, using the test method given in Annex J, the ratio, R , of the
L
lower versus the upper estimate mean values of the breaking load (for long sheets) or the bending moment
(for short sheets) for the exposed and unexposed specimens, determined at the 95 % confidence level after
56 d at 60 °C, shall not be less than 0,70.
5.4.8 Soak-dry performance
When tested in accordance with 7.3.11 or 7.3.12, using the test method given in Annex K, the ratio, R , of the
L
lower versus the upper estimate mean values of the breaking load (for long sheets) or the bending moment
(for short sheets) for the exposed and unexposed specimens, determined at the 95 % confidence level after
50 soak-dry cycles, shall not be less than 0,70.
5.5 Requirements concerning fire behavior
For the purpose of conformity with national regulations, products can be required to satisfy specific product or
system fire tests. The details of the specifications and acceptance criteria shall be defined by national
standards and/or regulations. Where no standard or performance requirement has been established, the
product shall be tested in accordance with ISO 12468-1 and the results classified in accordance with
ISO 12468-2.
5.6 Product performance
The categories and classes of fibre-cement profiled sheets defined in this International Standard might not be
considered to give an indication of the service life of the product. Product service life is influenced by factors
such as the geographical location, location of the product on the structure, type and method of installation and
applied surface coatings. This International Standard defines only minimum physical performance
requirements and does not prescribe material formulations. Therefore, it cannot be presumed that the service
life of fibre-cement profiled sheets of similar category and class made by various manufacturers are similar.
Service life can be estimated only for clearly specified product applications and products in defined climate
zones.
5.7 Requirements concerning impact resistance
For the purpose of conformity with national regulations, roof assemblies may be required to satisfy specific
requirements related to non-fragility in an effort to reduce the risk of people falling through roofs. The details of
the test specifications and acceptance criteria shall be defined by national standards and/or regulations. In
case information is required on the performance of the products used in the construction of such roof
assemblies, fibre-cement profiled sheets shall be tested by soft-body impact in accordance with the test
method in EN 15057.
6 Evaluation of conformity
6.1 General
The conformity of fibre-cement profiled sheets and fittings with the requirements of this International Standard
shall be demonstrated by
⎯ type testing, and
⎯ quality control by the manufacturer.
6.2 Type testing
6.2.1 General
Type tests shall be performed on products as delivered. If the same composition and production method is
used to produce sheets of various nominal sizes and thicknesses, it is necessary to perform type tests only on
one size of each nominal thickness.
Table 5 lists the characteristics that shall be subject to type testing, with the minimum performance
requirements and methods of test. All characteristics listed in Table 6 shall be subject to initial type testing.
6.2.2 Initial type testing
Initial type testing shall be performed to demonstrate conformity with this International Standard. Tests that
have been carried out previously on a product having the same physical characteristics and satisfying similar
conformity requirements and using the same test method and sampling procedure specified in this
International Standard may be taken into account.
12 © ISO 2011 – All rights reserved

For initial type testing where production variance is not yet known, an estimate of the average characteristic at
the 95 % confidence level shall be calculated.
Further type testing shall be carried out for the approval of a new product or where a fundamental change in
formulation or method of manufacture creates effects that 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 five years.
6.2.3 Additional type testing
Whenever a change is made in the design of the fibre-cement profiled sheets, in the raw materials or in the
production process that significantly changes one or more of the product characteristics, the type test shall be
performed for the appropriate characteristic(s).

6.3 Quality control (QC) system
6.3.1 General
The manufacturer shall establish and maintain a documented QC system that ensures that the products
placed into the market conform to the stated performance characteristics. The QC system shall consist of
procedures, regular inspections and tests and/or assessments of the incoming materials, components,
manufacturing equipment, manufacturing process and the product.
A manufacturer who establishes a quality management system in accordance with ISO 9001 is considered to
meet the above requirements.
The results of inspections, tests or assessments that require action shall be recorded, together with the
remedial actions taken.

6.3.2 Acceptance tests
6.3.2.1 The specifications of acceptance tests apply to the product as delivered, but the tests may be
carried out at an earlier stage of maturity.
When sampling from continuous production, testing of fibre-cement profiled sheets prior to coating and/or
under conditions other than those in Table 7 is acceptable, provided that it has been statistically established
(see Annex E) that compliance with the requirements in Table 5 is achieved.
Acceptance tests may also be used to confirm that a batch of profiled sheets conforms to this International
Standard, e.g. in conjunction with type tests or for receiving inspection.
The tests include
⎯ measurements of dimensions: length, width and thickness (method specified in Annex B);
⎯ measurement of mechanical characteristics: breaking load, bending modulus and bending moment
(methods specified in Annexes C and D);
⎯ measurement of apparent density (method specified in Annex F);
Each limit of specification for the characteristics in Table 6 shall be subject to an AQL of 4 %.
6.3.2.2 Minimum sampling schemes shall be carried out as follows:
a) for fibre-cement profiled sheets:
⎯ pitch: in accordance with ISO 2859-1;
⎯ height of corrugations: inspection by attributes;
⎯ height of edges, where applicable: double sampling;
⎯ height of edges, where applicable: AQL 4 %;
⎯ height of edges, where applicable: level S ;
⎯ breaking load and bending modulus: in accordance with ISO 3951-1;
⎯ bending moment inspection by variables, method σ or s;
⎯ apparent density AQL 4 %, level S

7.2.1 General
The measurements shall be made on profiled sheets and fittings as delivered, using the apparatus and
procedures given in Annex B.
7.2.2 Number and conditioning of specimens
The test shall be performed on whole (complete) sheets and fittings as delivered and without conditioning.
For type-testing, five sheets or fittings shall be taken; for acceptance testing and production control purposes,
the minimum sampling scheme (6.3.2.2) is applied.
7.3 Physical performance tests
7.3.1 General
Details of the number, preparation and conditioning of specimens for different tests are given in 7.3.2 to
7.3.12. Details of the test method and the apparatus for each test are given in Annexes B to K.
7.3.2 Breaking load and bending modulus
NOTE See Annex C.
For type-testing, 10 specimens shall be taken; for acceptance testing and production control purposes, the
minimum sampling scheme (see 6.3.2.2) is applied.
The test specimen shall be either a complete sheet (full length and width) or a transversely cut sheet (reduced
length, full width) with a minimum length of 1,20 m. If specimens with full width cannot be tested, the width
may be reduced by longitudinal cutting to a minimum of two complete corrugations, for sheet categories C, D
and E, and a minimum of three complete corrugations for sheet categories A and B. To avoid the introduction
of additional stress due to the longitudinal cutting, the width shall be slightly oversized, as shown in Figure 4.

7.3.3 Bending moment
NOTE See Annex D.
For type-testing, 10 specimens shall be taken; for acceptance testing and production control purposes, the
minimum sampling scheme (see 6.3.2.2) is applied.
The test specimen shall be taken from a complete sheet by cutting it transversely to a length of at least 0,3 m
but not more than 0,4 m and longitudinally, avoiding the edge corrugations, to a width as described below.
Specimens of sheets of constant thickness, as shown in Figure 2 a), should have a crown at the centre point
and one full pitch either side plus an overlap on the support bearers to a maximum of half a pitch each side
[see Figures 5 a) and 5 b)]. If the sheet width does not allow this, then reduce the sheet width to half of one
pitch each side of the central crown plus an overlap as defined above [see Figure 5 c)].
