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 15928-3 was prepared by Technical Committee ISO/TC 59, Building construction, Subcommittee SC 15,
Performance criteria for single family attached and detached dwellings.
ISO 15928 consists of the following parts, under the general title Houses — Description of performance:

Introduction
This part of ISO 15928 is one of a series under the general title: Houses — Description of performance. The
objective of this series is to identify the methods used to describe the performance of houses. Each part of
ISO 15928 relates to a separate attribute. The parts of ISO 15928 do not specify levels of performance and
they are not intended to replace national standards or regulations, but to provide a standardized framework to
enable the development of national standards and regulations in accordance with World Trade Organization
(WTO) requirements. The parts of ISO 15928 do not provide design methods and/or design criteria.
Based on the framework provided by ISO 15928 (all parts), purchasers, regulators and standard writers in
their respective countries can describe their requirements in standardized performance terms. Additionally, the
manufacturers/providers can respond by describing the performance of their products in a similar manner. The
purpose of ISO 15928 (all parts) is to provide a standardized system that can be used to specify performance
requirements and performance levels or to rate housing products.
NOTE The WTO Agreement on technical barriers to trade, Clause 2.8, states: “Whenever appropriate, members
shall specify technical regulations based on product requirements in terms of performance rather than design or
descriptive characteristics”.

design working life
design life assumed for the whole house
3.8
maintenance schedule
series of actions and time intervals between these actions to maintain the levels of structural safety and
serviceability performance of the whole house over the design working life
4 Structural durability performance
4.1 User needs
The structural safety and serviceability performance of the house shall be acceptable to the user over the
specified design working life.
A specified maintenance schedule can be required to achieve this. It is assumed that no significant human
abuse occurs.
4.2 Performance descriptions
The performance description for structural durability is the expression of the ability of the whole house and its
parts, with an appropriate degree of reliability, to fulfil its intended safety and serviceability performance in the
environment in which it is located over the specified design working life when subject to its intended use. This
is expressed in terms of one or more of the following:
a) external and internal environmental agents (including those associated with microclimates that can arise
in buildings);
b) maintenance schedule and specified component design life;
c) changes in form or properties.
NOTE 1 Performance in the environment refers to performance when subjected to the environmental agents listed in
Table A.1. This includes harmful substances and phenomena (e.g. aggressive ground water, acid rain, polluted air, insect
or rodent attack and fungal decay). It is necessary to consider the effects of severe events when defining the
environmental agents.

ISO 15928-3:2009(E)
NOTE 2 Changes in form or properties of components and materials induced by the environment can be described in
terms of:
a) change in basic properties of materials;
b) change in general or local dimensions of components;
c) change in properties or form of connection between components.
4.3 Principles for describing structural durability performance
The structural durability performance can be described in terms of
a) the component design life,
b) the maintenance schedule, and
c) the internal and external environmental agents that are likely to occur in the design working life.
The required maintenance should not be excessive, nor should the replacement of components be at
inappropriate levels. Maintenance requirements should be specified only for readily accessible components.
5 Parameters for the description of performance
5.1 Parameters for describing component design life
The component design life shall be described by specifying the minimum time, expressed in years, between
the replacement of structural components under the specified maintenance schedule.
5.2 Parameters for describing the maintenance schedule
The maintenance schedule shall be described by specifying the level of maintenance and frequency of
maintenance for the structural components and units.
NOTE Guidance on parameters required can be found in ISO 15686-5.
5.3 Parameters for describing internal and external environmental agents
5.3.1 General
The parameters for describing internal and external environmental agents considered relevant to the structural
durability are:
a) the geographical location of the house;
b) the parameters describing the influences of environmental agents affecting structural durability.
5.3.2 Parameters for geographical location
The parameters for describing geographical location include:
a) the distance from a coast-line, other geographical features or sources of pollutants;
b) the climate zone;
c) the physical location, e.g. latitude and longitude.

ISO 15928-3:2009(E)
5.3.3 Parameters describing environmental agents
5.3.3.1 The following influences should be considered:
a) moisture constituents;
b) moisture contaminants;
c) air constituents;
d) air contaminants;
e) ground constituents;
f) ground contaminants;
g) biological agents/life;
h) temperature;
i) solar radiation;
j) incompatible chemicals;
k) use or exposure.
5.3.3.2 Where appropriate, the following parameters should be used to quantify these influences:
⎯ duration of wetness;
⎯ duration of exposure;
⎯ freeze-thaw cycles;
⎯ temperature;
⎯ pH value for acidity;
⎯ concentration of chemicals and contaminants.
An assessment should be made as to whether these influences act either individually or in combination.
6 Evaluation
6.1 General
ISO 13823 describes the following two procedures for the evaluation of structural durability performance.
a) Service life format: This procedure consists of ensuring that the predicted structural design life of a whole
house or component, allowing for variations in durability, equals or exceeds the specified design life of the
house or component.
b) Limit state format: This procedure consists of ensuring that, at all the times during the specified design life
of the whole house or component, the performance requirements for structural safety and serviceability
are satisfied.

ISO 15928-3:2009(E)
6.2 Evaluation methods
6.2.1 General
Performance or properties for both whole house and components and material over time for a specified
environment and maintenance schedule can be determined by
a) field testing,
b) laboratory testing,
c) service experience,
d) analysis, or
e) a combination of the above.
6.2.2 Field testing
Full-scale dwellings, assemblies, components or materials in dwellings can be exposed to a real environment
for a stipulated length of time prior to the determination of structural safety or serviceability performance. It is
necessary that scientifically justified principles be used to relate the performance after the exposed time to
that at the design working life or component life, as appropriate.
NOTE Guidance on the relevant principles can be found in ISO 15686-2.
6.2.3 Laboratory testing
Accelerated ageing in laboratory facilities may be used for all testing (whether for whole dwellings,
components, assemblies or materials) prior to the determination of structural safety or serviceability
performance in accordance with the methods in ISO 15686-1 and ISO 15686-2. It is necessary that
scientifically justified principles be used to relate the performance in the laboratory test to that in reality.
6.2.4 Service experience
Service experience may be used in the assessment of the working life either of the whole house or of the
component life (see ISO 15686-2). It is necessary to derive the data from a sufficient number of representative
examples exposed to similar or more severe conditions. It is also necessary that construction methods,
components and materials be similar to those of the houses being analysed. It is necessary to have available
adequate documentation of environments and the performance over time.
NOTE Guidance on appropriate methods to extract service life data from the appraisal of existing buildings can be
found in ISO 15686-7.
6.2.5 Analysis
Analytical methods may be used to assess the durability performance of individual components. Individual
component analysis is required to assess
a) the change in form or properties over the component design lifetime, taking into account the maintenance
schedule and the environmental agents;
b) the effect of these changes on structural safety and serviceability performance.
6.2.6 Combination
A combination of field and laboratory testing, service experience and analysis may be used for evaluation.

Commentary
A.1 General
This annex includes background information on this part of ISO 15928, guidance on its use and suggestions
on good practice.
A.2 Comments on the Scope (Clause 1)
The purpose of this part of ISO 15928 is to standardize the method of describing the structural durability
performance for housing, i.e. to standardize the parameters by which the structural durability aspects of house
performance are expressed or defined. This part of ISO 15928 does not specify a level of performance and it
is not intended to provide design method and/or criteria.
It is one in a series of parts that together comprise ISO 15928, which is designed to facilitate the
communication between the specifier (buyer/user) and the provider (seller). Durability and safety attributes are
covered in other parts of ISO 15928.
The intent is to provide a standardized system that can be used to realize performance description.
The objectives of this part of ISO 15928 are as follows:
a) to facilitate international trade in housing systems and housing products, and to exchange housing
information and knowledge by eliminating technical barriers;
b) to facilitate innovation in housing by providing a systematic framework for evaluation and acceptance;
c) to establish user needs related to structural serviceability in specific technical engineering terms, in order
to facilitate communication among all stakeholders.
