34 ELECTRIC SHAVERS FOR HOUSEHOLD USE – EVALUATION OF USER
35 EXPERIENCE AND USER SATISFACTION
37 FOREWORD
39 1） The International Electrotechnical Commission (IEC) is a worldwide organization for
40 standardization comprising all national electrotechnical committees (IEC National
41 Committees). The object of IEC is to promote international co-operation on all questions
42 concerning standardization in the electrical and electronic fields. To this end and in addition to
43 other activities, IEC publishes International Standards, Technical Specifications, Technical
44 Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
45 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National
46 Committee interested in the subject dealt with may participate in this preparatory work.
47 International, governmental and non-governmental organizations liaising with the IEC also
48 participate in this preparation. IEC collaborates closely with the International Organization for
49 Standardization (ISO) in accordance with conditions determined by agreement between the
50 two organizations.
51 2）The formal decisions or agreements of IEC on technical matters express, as nearly as
52 possible, an international consensus of opinion on the relevant subjects since each technical
53 committee has representation from all interested IEC National Committees.
54 3）IEC Publications have the form of recommendations for international use and are accepted
55 by IEC National Committees in that sense. While all reasonable efforts are made to ensure that
56 the technical content of IEC Publications is accurate, IEC cannot be held responsible for the
57 way in which they are used or for any misinterpretation by any end user.
58 4）In order to promote international uniformity, IEC National Committees undertake to apply
59 IEC Publications transparently to the maximum extent possible in their national and regional
60 publications. Any divergence between any IEC Publication and the corresponding national or
61 regional publication shall be clearly indicated in the latter.
62 5）IEC itself does not provide any attestation of conformity. Independent certification bodies
63 provide conformity assessment services and, in some areas, access to IEC marks of
64 conformity. IEC is not responsible for any services carried out by independent certification
65 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
68 individual experts and members of its technical committees and IEC National Committees for
69 any personal injury, property damage or other damage of any nature whatsoever, whether
70 direct or indirect, or for costs (including legal fees) and expenses arising out of the publication,
71 use of, or reliance upon, this IEC Publication or any other IEC Publications.
72 8）Attention is drawn to the Normative references cited in this publication. Use of the
73 referenced publications is indispensable for the correct application of this publication.
74 9）Attention is drawn to the possibility that some of the elements of this IEC Publication may
75 be the subject of patent rights. IEC shall not be held responsible for identifying any or all such
76 patent rights.
77 International Standard IEC 61254 has been prepared by subcommittee 59L: Small household
78 appliances, of IEC technical committee Performance of household and similar electrical
79 appliances:
80 The text of this standard is based on the following documents:
IEC CDV 61254 ED2 © IEC 2025 - 4 - 59L/290/CDV

83 Full information on the voting for the approval of this standard can be found in the report on
84 voting indicated in the above table.
85 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
86 The committee has decided that the contents of this publication will remain unchanged until
87 the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data
88 related to the specific publication. At this date, the publication will be
89 • reconfirmed,
90 • withdrawn,
91 • replaced by a revised edition, or
92 • amended.
93 The National Committees are requested to note that for this publication the stability date is
94 XXXX.

100 ELECTRIC SHAVERS FOR HOUSEHOLD USE – EVALUATION OF USER
101 EXPERIENCE AND USER SATISFACTION
103 1 Scope
104 This document applies to men’s electric shavers and their trimmers for household use.
105 This document deals with the methods of evaluating user experience and user
106 satisfaction, in subjective way, for men’s electric shavers and their trimmers with a rated
107 voltage not greater than 250V.
108 This document does not specify safety or performance requirements.
109 2 Normative references
110 The following referenced documents are indispensable for the application of this
111 document. For dated references, only the edition cited applies. For undated references,
112 the latest edition of the referenced document (including any amendments) applies.

142 4 List of evaluations
143 Depending on the appliance, the following evaluations shall be carried out, as appropriate:
144 4.1 User experience for comparing different electric shavers
145 4.2 User satisfaction for a particular electric shaver
146 --User satisfaction with regard to performances and features of a particular electric shaver;
147 --User satisfaction with regard to overall aspects of a particular electric shaver.
148 5 Evaluation of user experience for comparing different electric shavers
149 5.1 Composition of the test panels
150 Each panel is to be composed so that it is reasonably representative of the adult male population
151 of the country in which the test is performed, with particular attention being paid to hair density,
152 rate of beard growth, toughness of the beard, sensitivity towards skin irritation, and the time
153 taken to shave.
154 Each panel tester shall have no pains or injuries on the face and have no allergic skin.
155 Each panel tester shall be the potential user and have a positive attitude towards the functions
156 and not be influenced by preconceived ideas.
157 The test panel is divided into subpanels with equal size. Each subpanel represents one of the
158 two basic electric shaver systems:
159 -- rotary electric shaver testers.
160 -- vibratory electric shaver testers.
161 For statistical reasons, the number of testers in each of the above subpanels should be at least
162 12.
