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 60811-401 has been prepared by IEC technical committee 20:
Electric cables.
This Part 401 of IEC 60811 cancels and replaces 8.1 and 8.4 of IEC 60811-1-2:1985, 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.
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.

4 Test method
4.1 General
This part of IEC 60811 shall be used in conjunction with IEC 60811-100.
Unless otherwise specified, tests shall be carried out at room temperature.
An ageing treatment in an air oven may be required by the relevant cable standard:
a) for prepared test pieces of insulating or sheathing material only (see 4.2.3.2);
b) for prepared test pieces of cores (conductor and insulation) (see 4.2.3.2 and 4.2.3.3 if
necessary);
---------------------- Page: 12 ----------------------
SIST EN 60811-401:2012
60811-401 IEC:2012 – 7 –
c) for test pieces of completed cable (see 4.2.3.4);
d) for the loss of mass test (see IEC 60811-409).
The ageing test a) or b) and the loss of mass test d) may be combined and carried out on the
same test pieces when the aging time and aging temperature are the same.
In general, mechanical characteristics are measured after treatment, but in some cases, the
conductor and the separator, if any, cannot be removed without damaging the insulation and a
2
bending test is realized on the circular conductor up to and including 16 mm . Ageing followed
by the bending test is considered the acceptance procedure in case of dispute.
4.2 Influence of the ageing treatment on the mechanical characteristics
4.2.1 Apparatus
The ageing treatment is realized in an oven with natural air flow or air flow by pressure. The
air shall enter the oven in such a way that it flows over the surface of the test pieces and
leaves near the top of the oven. The oven shall have not less than 8 and not more than 20
complete air changes per hour at the specified ageing temperature. Two test methods for
measuring air flow through an oven are given in Annex A.
