FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
The IEC 63044 series deals with developing and testing home and building electronic systems
(HBES) and building automation and control systems (BACS).
The expression HBES/BACS covers any combination of HBES and/or BACS devices including
their separate connected/detachable devices linked together via one or more networks.
This document applies to HBES/BACS devices and defines the environmental conditions in
which these devices are to be used when so declared by the manufacturer.

Part 2: Environmental conditions

1 Scope
This part of IEC 63044 provides the environmental conditions for HBES/BACS devices, when
declared in the manufacturer's documentation for use in one or more of the environment classes
as defined in Clause 6 of this document.
This document focuses on the following environmental conditions:
– climatic environmental conditions,
– chemical environmental conditions,
– mechanical environmental conditions,
– biological environmental conditions.
This document does not supersede the relevant product standard, if any, and applies only in
addition to the relevant products standard when it is referred to in the manufacturer's
documentation. It is intended to support the particular manufacturer's declaration or any
agreement on environmental conditions between customer and manufacturer.
This document is not intended to give guidance on requirements and tests for the drafting of
product standards.
The document provides an overview of environmental conditions for devices operating in
weather-protected and non-weather-protected locations, ship environments, portable use and
also for storage and transport.
