MATTING OF INSULATING MATERIAL FOR ELECTRICAL PURPOSES
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61111 has been prepared by IEC technical committee 78: Tools
for live working.
This consolidated version of IEC 61111 consists of the first edition (1992) [documents
78(CO)63/FDIS and 78(CO)67/RVD], its corrigendum May 2000 and its amendment 1 (2002)
[documents 78/436/FDIS and 78/457/RVD].
The technical content is therefore identical to the base edition and its amendment and has
been prepared for user convenience.
It bears the edition number 1.1.
A vertical line in the margin shows where the base publication has been modified by
corrigendum and amendment 1.
Annexes A, B, C and D form an integral part of this standard.
Annexes E, F and G are for information only.
The committee has decided that the contents of the base publication, its corrigendum May
2000 and its amendment will remain unchanged until 2008. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

SIST-TS CLC/TS 61111:2007
61111 © IEC:1992+A1:2002 – 17 –
Non-harmful physical irregularities shall be defined as surface irregularities present on either
surface of the matting due to imperfections on forms or moulds or other imperfections inherent
to the manufacturing process. These irregularities appear as mould marks that look like cuts
even though they are actually a raised ridge of elastomer, indentations, or protuberances that
are acceptable provided that:
a) the thickness at any irregularity conforms to the thickness requirements. Surface design to
improve slip resistance shall not be considered as irregularities;
b) he indentations, protuberances or mould marks tend to blend into a smooth slope upon
stretching of the material.
6.5 Marking
6.5.1 Each matting which is claimed to comply with the requirements of this standard shall
be marked with the following:
– symbol IEC-60417-5216 – Suitable for live working; double triangle (see annex A);
– number of the relevant IEC standard immediately adjacent to the symbol;
– name, trademark, or identification of the manufacturer;
– category if applicable;
– class;
– month and year of manufacture.
In the case of rolls they shall be marked on one border at least every metre with the class.
6.5.2 The marking shall be clearly visible, durable and shall not impair the quality of the
matting.
The durability of the marking is checked by rubbing the marking for 15 s with a piece of lint-

7 Tests on matting
7.1 General
There are four kinds of tests: type, routine, sampling and acceptance. These are defined in
clause 3: Definitions.
Each of the following subclauses defines whether type, routine or sampling tests are required.
In order to carry out the type tests, it is necessary to have 16 mats.
The allotment of this matting in various testing lots, the size of each lot, and the order in
which these tests are carried out are given in annex B.
The test location conditions shall be in accordance with IEC 60160, clause 4.
Unless otherwise specified, matting shall be preconditioned for a period of 2 ± 0,5 h at a
temperature of 23 °C ± 2 °C and relative humidity of 50 % ± 5 % (see IEC 60212 standard
atmosphere B).
In the case of matting in rolls, the minimum size of each unit shall be 1 m × 1 m. For rolls with
a width of less than 1 m, the manufacturer shall provide a test piece of 1 m × 1 m.
7.2 Visual inspection and measurements
7.2.1 Shape
Type test and sampling test (see 6.1)
The shape shall be verified by visual inspection.
7.2.2 Dimensions
Type test and sampling test (see 6.2)
The dimensions as specified in table 1 shall be verified with the matting in a flattened
condition.
7.2.3 Thickness
Type test and sampling test (see 6.3)
Thickness measurements shall be made at five or more points approximately uniformly
distributed over the total area of the matting sample.
Measurements shall be made with a micrometer or any alternative instrument giving
substantially the same results. The micrometer shall be graduated to within 0,02 mm, have an
anvil of 6 mm in diameter, and a flat presser foot 3,17 mm ± 0,25 mm in diameter.
The presser foot shall exert a total force of 0,83 N ± 0,03 N. Sufficient support shall be given
the matting so that it will present an unstressed flat surface between the anvil faces of the
micrometer.
In case of dispute, the micrometer method described above shall be used.
