Part One: General Requirements
Section Three - Environmental testing
1. Scope
This standard specifies environmental test methods to be used for
testing system components of an alarm system.
This standard does not preclude the use of other environmental
exposures having special characteristics suitable for the evaluation of
special environmental conditions.
Requirements, performance criteria, test schedules, etc., are not
covered by this standard, but are to be given in the specific
standards for the particular alarm systems and/or components.
This standard shall be used in conjunction with the following IEC
publications.
Publications:
839-1-1: Alarm systems, Part 1: General requirements. Sec-
tion One - General. (Under consideration.)
801-1 (1984): Electromagnetic compatibility for industrial-process
measurement and control equipment, Part 1: General
introduction.
2. Object
The object of this standard is to provide a standard range of tests
to determine the suitability of components and equipment for use,
storage and transportation under various environmental conditions.

4. General considerations
4.1 This standard contains a selection of environmental test methods
taken from other standards including IEC Publication 68.
4.2 The selected test methods have been found suitable for testing
components of an alarm system and have the necessary reproducibility
and severities suitable for this field of application.
For general guidance on environmental testing, reference should be
made to IEC Publication 68-1.
For specific guidance on the various environmental test methods used
in this standard, reference should be made to the description of the
relevant test.
4.3 Classification of tests
This standard specifies a range of test methods with a number of
test severities in order to cover the need for relevant tests for each
system component.
The aim of each test is characterized by allocation of the test to one
of the following two test classes:
a)
Class A - Operation tests
The object of a test in Class A is:
i)
to demonstrate the ability of the specimen to operate correctly
under the influence of the normal service environment and/or
ii)
to demonstrate the immunity of the specimen to false alarm
under the influence of a particular service environment.
The test specimen is exposed to an environment corresponding in
its effects to the normal service environment.
b) Class B - Accelerated tests
The object of a test in Class B is to demonstrate the ability of the
specimen to survive under the influence of an artificial environ-
ment more severe than the normal service environment.
The test specimen is subjected to exposures, which are intention-
ally more severe that the service environment, in order to give
information about the long-term stability.
839-1-3 (1) © IEC - 11 -
The specimen shall be switched off during all Test B exposures.
See Appendix B of IEC Publication 68-1.
4.4 Identification of tests
References in other parts of the standard to a specific environmental
test in this part of the standard shall be identified as follows:
Example: lEC 839-1-3/ A - 1/1
This part
Test class, for example A: Operation tests

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 60811 series specifies the test methods to be used for testing non-metallic materials
of all types of cables. These test methods are intended to be referenced in standards for
cable construction and for cable materials.
NOTE 1 Non-metallic materials are typically used for insulating, sheathing, bedding, filling or taping within cables.
NOTE 2 These test methods are accepted as basic and fundamental and have been developed and used over
many years principally for the materials in all energy cables. They have also been widely accepted and used for
other cables, in particular optical fibre cables, communication and control cables and cables for ships and offshore
applications.

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.
This consolidated version of the official IEC Standard and its amendment has been prepared
for user convenience.
IEC 60811-410 edition 1.1 contains the first edition (2012-03) [documents 20/1294/FDIS and
20/1343/RVD] and its amendment 1 (2017-07) [documents 20/1734/FDIS and 20/1739/RVD].
In this Redline version, a vertical line in the margin shows where the technical content is
modified by amendment 1. Additions are in green text, deletions are in strikethrough red text. A
separate Final version with all changes accepted is available in this publication.
