AMENDMENT 2
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
Amendment 2 to IEC 60811-501:2012 has been prepared by IEC technical committee 20:

4 Test method
4.2 Insulation
4.2.1 General
Replace the existing second paragraph, modified by IEC 60811-501:2012/AMD1:2018, and
existing note with the following three new paragraphs:
When the ageing treatment is to be carried out on prepared test pieces (in accordance with
IEC 60811-401), the test pieces for the ageing treatment shall be from positions adjacent to the
test pieces used for the test without ageing. The preparation and conditioning of test pieces for
the ageing treatment and test pieces without ageing shall be the same.
Where further increased test reliability is necessary, then the tests on aged and unaged test
pieces shall be performed by the same person using the same testing method and the same
apparatus, in the same laboratory.
It is recommended that the tensile tests on the aged and unaged test pieces are made in
immediate succession. Further, it is recommended to retain unaged samples at laboratory
conditions for possible future testing.

Replace the existing fourth paragraph of item a) with the following new paragraph:
The measurements shall be carried out by using a suitable instrument, for example an optical
device, a dial gauge or a micrometer, giving a contact pressure not exceeding 0,07 N/mm .
4.3 Sheath
4.3.1 General
Replace the existing second paragraph and note with the following three new paragraphs:
When the ageing treatment has to be carried out on prepared test pieces (in accordance
with IEC 60811-401 or with IEC 60811-404), the test pieces for the ageing treatment shall be
from positions adjacent to the test pieces used for the test without ageing.
Where further increased test reliability is necessary, then the tests on aged and unaged test
pieces shall be performed by the same person using the same testing method and the same
apparatus, in the same laboratory.
It is recommended that the tensile tests on the aged and unaged test pieces are made in
immediate succession. Further, it is recommended to retain unaged samples at laboratory
conditions for possible future testing.
