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 International Standard may be the
subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 9125 was prepared by Technical Committee ISO/TC 77, Products in fibre reinforced cement.

Introduction
The purpose of this International Standard is to provide manufacturers and purchasers with uniform
requirements for fibre-cement slate products. These requirements are performance based, and have been
specified with the objective of ensuring product quality, industry efficiency, and the performance of the product
in service.
In the development of this International Standard the technical committee had as an objective the
harmonization, where possible, with other national fibre-cement standards, i.e. those of the European
Committee for Standardization (CEN), American Society for the Testing of Materials (ASTM), Japanese
Industrial Standards Committee (JIS), to facilitate and promote uniform performance benchmarks for the
global use of fibre-cement products.

appropriate national or international application code or standard.
This International Standard applies to fibre-cement slates with a height dimension not exceeding 850 mm for
overlapping assembly (see 5.4).
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 ISO or national standards.
This International Standard does not apply to fibre-cement slates reinforced with asbestos fibres.
This International Standard does not include calculations for installation requirements, wind uplift or rain
proofing of the installed products.
NOTE National standards for installation requirements can be adopted.

3.1
acceptance test
test to establish whether a batch of sheets conforms to a specification
[Adapted from ISO 390:1993, 3.5]
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 Clause 6.
3.2
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, or ISO 3951-1.

---------------------- Page: 9 ----------------------
ISO 9125:2009(E)
5.4 Dimensions and tolerances
5.4.1 General
The manufacturer shall specify the shapes, sizes and configuration of edges of the fibre-cement slates.
Fittings shall have nominal dimensions and shapes determined by the manufacturer and appropriate to the
corresponding fibre-cement slates.
5.4.2 Thickness
The manufacturer shall specify the nominal thickness of the slates.
The nominal thickness of the fittings shall be not less than the corresponding nominal thickness of the fibre-
cement slates with which the fittings are being used.

5.5 Physical requirements and characteristics
5.5.1 General
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 failure of the
product.
5.5.2 Mechanical characteristics
When tested as specified in 7.3.2, using the method given in Annex C, the slates shall have a minimum
bending moment in accordance with Table 2. This bending moment shall be the average of the values
obtained from testing the test specimen in both directions.
The minimum bending moment at rupture in the weaker direction shall not be less than 60 % of the values
specified in Table 2 for the average of both directions.

The following special class is also available:
Class BS: When higher bending moments are required for batten spacings W 250 mm, the required minimum shall be
equivalent to the numerical value of h/5.
NOTE 1 Values stated in this table are the minimum values at 4 % AQL. Minimum values (4 % AQL) for this property are declared by
the manufacturer.
NOTE 2 For acceptance testing, it is necessary to use the 4 % AQL values.
NOTE 3 For initial type testing, where production variance is not yet known, it is necessary to calculate an estimate of the mean
bending moment at the 95 % confidence level to determine the class (see C.6.2).
5.5.3 Apparent density
The manufacturer’s literature shall specify the minimum apparent density of the slates. When tested in
accordance with 7.3.3, using the method given in Annex E, the density shall not be less than the specified
value.
5.5.4 Water permeability
When tested for water permeability in accordance with 7.3.4, using the method given in Annex F, traces of
moisture may appear on the underside of the specimen but in no instance shall there be any formation of
water drops.
5.5.5 Freeze-thaw performance
Slates are divided into two categories according to their freeze-thaw performance; see Table 3.
For countries where there are, under normal circumstances, no or only occasionally temperatures below 0 °C,
determination of freeze-thaw performance is not necessary (category I).
6 © ISO 2009 – All rights reserved
---------------------- Page: 11 ----------------------
ISO 9125:2009(E)
When freeze-thaw testing is required (category II), slates are tested in accordance with 7.3.5, using the test
method given in Annex G. After 100 freeze-thaw cycles, the ratio, R , of the lower estimate mean values of the
L
bending moments for the exposed and unexposed specimens, determined at the 95 % confidence levels, shall
not be less than 0,75.
Table 3 — Number of freeze-thaw cycles

II 100
5.5.6 Heat-rain performance
When tested in accordance with 7.3.6, using the test method given in Annex H, after 50 heat-rain cycles, any
visible cracks, delamination or other defects in the slates shall not be sufficient to affect their in-use
performance.
5.5.7 Warm-water performance
When tested in accordance with 7.3.7, using the test method given in Annex I, after 56 days at 60 °C, the
ratio, R , of the lower estimate mean values of the bending moment for the exposed and unexposed
L
specimens, determined at the 95 % confidence level, shall not be less than 0,75.
5.5.8 Soak-dry performance
When tested in accordance with 7.3.8, using the test method given in Annex J, after 50 soak-dry cycles, the
ratio, R , of the lower estimate mean values of the bending moment for the exposed and unexposed
L
specimens, determined at the 95 % confidence level, shall not be less than 0,75.
5.6 Requirements concerning fire
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 according to ISO 12468-1 and the results classified in accordance with ISO 12468-2.
5.7 Product performance
The categories and classes of fibre-cement slates defined in this International Standard (see 5.2) cannot be
considered to give an indication of the service life of the product. Product service life is influenced by factors
such as geographical location, location of product on structure, type and method of installation and applied
surface coatings. This International Standard only defines minimum physical performance requirements but
does not prescribe material formulations. Therefore, the presumption that the service life of fibre-cement
slates of similar category and class made by various manufacturers is similar cannot be made. Service life can
be estimated only for clearly specified product applications and products in defined climate zones.

6 Evaluation of conformity
6.1 General
The conformity of fibre-cement slates and fittings with the requirements of this International Standard shall be
demonstrated by
⎯ type testing;
⎯ quality control by the manufacturer.
6.2 Type testing
6.2.1 General
Type tests shall be made on products as delivered. If the same composition and production method is used to
produce slates of various nominal sizes and thicknesses, it is necessary to make type tests only on the
maximum and minimum dimensions.
Table 4 lists the characteristics that shall be subject to type testing with the minimum performance
requirements and methods of test. All characteristics listed in Table 5 shall be subject to initial type testing.
Testing of mechanical characteristics is made with the upper face in compression.

6.2.2 Initial type testing
Initial type testing shall be performed to demonstrate conformity with this International Standard. Tests that
have been made previously (on a product having the same physical characteristics and satisfying similar
conformity requirements), using the same test method and sampling procedure specified in this document,
may be taken into account.
For initial type testing, where production variance is not yet known, it is necessary to calculate an estimate of
the average characteristic at the 95 % confidence level.
Additional type testing shall be made 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 5 years.
6.2.3 Further type testing
Whenever a change in design occurs that significantly changes one or more of the product characteristics of
the fibre-cement slates, the raw materials, or the production process, the type test shall be performed for the
appropriate characteristic(s).
6.3 Quality control system
6.3.1 General
The manufacturer shall establish and maintain a documented quality control (QC) system that ensures that
the products delivered to 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 according to 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
The specifications of acceptance tests apply to the p
