44 FOREWORD
45 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
46 electrotechnical committees (IEC National Committees). The object of IEC is to promote international co -operation on all
47 questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities ,
48 IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS)
49 and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC
50 National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental
51 and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with
52 the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between
53 the two organizations.
54 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus
55 of opinion on the relevant subjects since each technical committee has representation from all interested IEC National
56 Committees.
57 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in
58 that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC
59 cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
60 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to
61 the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and
62 the corresponding national or regional publication shall be clearly indicated in the latter.
63 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment
64 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
65 independent certification bodies.
66 6) All users should ensure that they have the latest edition of this publication.
67 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of
68 its technical committees and IEC National Committees for any personal injury, property damage or other damage of any
69 nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publicatio n,
70 use of, or reliance upon, this IEC Publication or any other IEC Publications.
71 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable
72 for the correct application of this publication.
73 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.
74 IEC shall not be held responsible for identifying any or all such patent rights.
75 IEC 63203-201-4 has been prepared by IEC technical committee 124: Wearable electronic devices and
76 technologies.
77 The text of this International Standard is based on the following documents:

94 INTRODUCTION
95 The electrical property can be changed by surface wear of conductive fabric so abrasion resistance is
96 a critical property for conductive fabric.
97 The failure modes of conductive fabric are specimen breakdown, appearance change and damage of
98 coated layer in case of coated fabric etc. These physical failure modes result in changes in electrical
99 property.
100 This document specifies the test method and evaluation criteria to abrasion resistance of conductive
101 fabrics.

105 Part 201-4: Electronic textile –Test method for determining sheet resistance of
106 conductive fabrics after abrasion
108 1 Scope
109 This part of IEC 63203-201 specifies a test procedure to measure electrical resistance of conductive
110 fabrics after abrasion treatment using Martindale abrader.
111 This document is applicable to woven, knitted conductive fabrics, conductive nonwovens, coated
112 conductive fabrics, and embroidery fabrics using conductive yarns.
113 2 Normative references

115 constitutes requirements of this document. For dated references, only the edition cited applies. For
116 undated references, the latest edition of the referenced document (including any amendments) applies.

S
137 electrical resistance of a sheet of nominally uniform thickness, measured across the opposite ends of a
138 square area.
139 Note 1 to entry: The unit of sheet resistance is Ohm (Ω). However, in order not to confuse sheet resistance with bulk resistance,
140 the use of Ohm per square (Ω/□) is recommended.
141 Note 2 to entry: If fabric thickness is known, the average bulk resistivity of the fabric material can be calculated as the product
142 of sheet resistance and fabric thickness.

143 Note 3 to entry: In a conductive fabric whose resistance value can be regarded as isotropic, the fabric can be regarded as a
144 sheet and the sheet resistance can be used as an expression of conductivity.
