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.

This second edition cancels and replaces ISO 9384:1991 together with the first edition (ISO 9125:1990),
which has been technically revised. It also incorporates the amendment ISO 9125:1990/Amd.1:2004 and the
technical corrigenda ISO 9125:1990/Cor.1:1993 and ISO 9125:1990/Cor.2:2005.

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.

INTERNATIONAL STANDARD ISO 9125:2009(E)

Fibre-cement slates and fittings — Product specification
and test methods
1 Scope
This International Standard specifies technical requirements and methods for the inspection and testing of
fibre-cement slates and shingles and their fibre-cement fittings, designed to protect the weather-exposed
surfaces on roofs and claddings 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.
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.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

acceptance quality limit (AQL) for lot-by-lot inspection

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
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.
3.3
ambient conditions
ambient laboratory conditions
temperature: 23 °C ± 10 °C
relative humidity: 50 % ± 20 %
3.4
apparent density
dry mass per unit volume based upon the volume of the sample calculated by water displacement or
equivalent
NOTE This is an average density of the material and pores coated or uncoated (as delivered).
3.5
as delivered
as the producer intends to supply the product after completing all aspects of the process including maturing
and, when appropriate, coating
3.6
reinforcement fibres
organic or inorganic reinforcement fibres for the manufacture of fibre-cement slates complying with this
International Standard
(See 5.2.2.)
3.7
type test
test made 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
