IEC 60811-409:2012

Electric and optical fibre cables - Test methods for non-metallic materials - Part 409: Miscellaneous tests - Loss of mass test for thermoplastic insulations and sheaths

IEC 60811-409:2012 gives the procedure for measuring the loss of mass which normally applies to PVC insulations and sheaths. IEC 60811-409:2012 cancels and replaces Clause 8 of IEC 60811-3-2:1985, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. There are no specific technical changes with respect to the previous edition, but see the Foreword to IEC 60811-100:2012.
This publication is to be read in conjunction with IEC 60811-100:2012.

Câbles électriques et à fibres optiques - Méthodes d'essai pour les matériaux non-métalliques - Partie 409: Essais divers - Essai de perte de masse des enveloppes isolantes et gaines thermoplastiques

La CEI 60811-409:2012 décrit la procédure à suivre pour mesurer la perte de masse, généralement applicable aux enveloppes isolantes et aux gaines en PVC. La CEI 60811-409:2012 annule et remplace l'Article 8 de la CEI 60811-3-2:1985, qui est supprimée. L'ensemble des informations relatives aux remplacements figurent dans l'Annexe A de la CEI 60811-100:2012. Aucune modification technique n'a été effectuée par rapport à l'édition précédente; voir cependant l'avant-propos de la CEI 60811-100:2012.
Cette publication doit être lue conjointement avec la CEI 60811-100:2012.

FOREWORD
I) The formal decisions of agreements of the I EC on technical matters, prepared by Technical Committees on which all the
National Committees having a special interest therein are represented, express, as nearly as possible, an inte rnational consensus
of opinion on the subjects dealt with.
2) They have the form of recommendations for inte
rnational use and they are accepted by the National Committees in that
sense.
3) In order to promote intern
ational unification, the I EC expresses the wish that all National Committees should adopt the text of
the I E C recommendation for their national rules in so far as national conditions will permit. Any divergence between the I EC
recommendation and the corresponding national rules should, as far as possible, be clearly indicated in the latter.

test methods and performance criteria
1. Scope
This standard specifies the requirements, test methods and performance criteria for power
supply units for alarm systems. The specific requirements for particular system components are
specified in separate standards, which shall be used in conjunction with this standard. The
configuration of the power supply will depend upon the available sources of power and the
requirements of the alarm systems and shall consist of one or more of the following:
a) Primary batteries.
b) Secondary batteri
es (with or without a built-in charger from an external safety extra low
voltage source (SELV)).
c)
Power units with mains supply via safety isolating transformer,
i)
with no other components;
ii)
with a rectifier for supplying direct current;
iii)
with a secondary battery and charger as back-up supply;
iv) with a primary battery as a back-up supply;
v) incorporating an inverter or "switching mode" unit.
d) A combination of the types indicated in a), b) and c) to form a composite power supply
unit.
Certain central stations use higher voltages which are not considered in this standard.
2. Object
The object of this standard is to specify requirements, test methods and performance criteria for
electrical power units for use as pa rt of an alarm system.

4. Definitions
For the purpose of this standard the following definitions apply.
4.1 Final voltage
The voltage to which a battery falls when discharged under specified conditions.
Power unit
4.2
A device that modifies, stores or isolates electrical power for an alarm system, either as a
of control and indicating equipment, and provides power for an
separate unit or as an integral pa rt
alarm and for the system under normal, alarm and fault conditions.
5. Requirements
5.1 Primary cells
Primary cells shall comply with the requirements of I EC Publication 86, except that where
technically more advanced types are specified (e.g. lithium cells), these may be specified as long as
they cannot cause a hazard or substantial loss of performance of the alarm system.
5.2 Secondary cells
5.2.1 Any type of secondary cells may be used. If nickel-cadmium cells are used they shall comply with
the relevant standard:
—IEC Publication 285.

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.
International Standard IEC 60811-409 has been prepared by IEC technical committee 20:
Electric cables.
This Part 409 of IEC 60811 cancels and replaces Clause 8 of IEC 60811-3-2:1985, which is
withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012.

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.
