6.5 Location and mounting of appliances
6.5.1 Replacement:
For measurement on carpet:
The vacuum cleaner is located on the standard test carpet Wilton (defined in 3.103) placed
directly without any resilient means:
– either on the floor of the hard-walled test room or the special reverberation test room with
a minimum distance of 1 m between any surface (including protruding parts) of the
appliance and the nearest wall;,
– or on the reflecting plane of the free-field environment, taking into account the shape and
the size of the specified measurement surface.
The vertical projection of the shape of the appliance under test and its cleaning head shall be
at the centre of the carpet area (see Figures 101 and 102).
The axis of longitudinal travelling of the cleaning head shall be parallel with the direction of
the pile of the carpet (x-axis). The angle α between the transverse axis of the cleaning head
(parallel with y-axis) and the longitudinal axis of the appliance (or the tube, if any) shall be
α = (90 ± 5)° (see Figures 101 and 102).
For measurements on standard hard floor:
The vacuum cleaner is located on the standard hard floor (defined in 3.104) placed directly
without any resilient means:
– either on the floor of the hard-walled test room or the special reverberation test room with
a minimum distance of 1 m between any surface (including protruding parts) of the
appliance and the nearest wall,
– or on the reflecting plane of the free-field environment, taking into account the shape and
the size of the specified measurement surface.

Generally the floor in a hard-walled test room, a special reverberation test room or in a hemi-
anechoic test room fulfils the requirements for a standard hard floor (3.104).
If the requirements for a standard hard floor are not met two plates made of marble or similar
natural stone with a polished surface shall be used. The size of the plates shall be at least
0,5 m × 1,0 m; thickness shall be at least 0,02 m. Care is to be taken to prevent additional
noise production between the plates and between plates and floor.
NOTE 101 To avoid additional noise production a resilient underlay with a thickness of 25 mm, mechanical loss
factor 0,25 and a dynamic E-modulus less than 0,2 N/mm shall be used. The foam Getzner Sylomer® SR11
fulfils these requirements (www.getzner.com).
The vertical projection of the shape of the appliance under test and its cleaning head, shall be
at the centre of the test area (see Figures 101 and 102).
If the cleaning head is connected by a hose and connecting tube(s) to the appliance, the
cleaning head is placed close to the appliance on the carpet so that the projection of the axis
of longitudinal travelling of the cleaning head and that of the longitudinal axis of the appliance
are parallel, the projections of the appropriate transverse axis coincide and the clearance
between the projection of the appliance and the projection of the cleaning head is (2 ± 1) cm.
In the case of a hard floor measurement, the placement of cleaning head, connecting hose,
tubes and appliance is done as if it were placed on a 1 m × 1 m carpet, to ensure a
sufficiently compact placement of the various elements. The hose and connecting tube(s) or
the handles of hand-supported and upright vacuum cleaners are resiliently suspended or
supported in normal position of use (middle of the handles at (80 ± 5) cm above the floor, if
possible), the cleaning head being in full contact with the floor.
Telescopic connecting tubes should be adjusted in accordance with the owner’s manual. If no
instructions are given, then the length of the telescopic connecting tubes shall be adjusted so
+5
that the angle β between the telescopic connecting tubes and the floor shall be β = (45 )°
or, if not possible, as near as possible to 45°.
If necessary the cleaning head is resiliently fastened to prevent self-propulsion.
Sound radiation due to possible vibrations of the test floor should be prevented.
The test floor is considered to be a part of the appliance to be tested and its possible
influence on the acoustical characteristics of the test environment, for example of the hard
reflecting plane, or on the absorption (reverberation time) of the reverberant test room or
hard-walled room should not be taken into account.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l’IEC). L’IEC a pour
objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines
de l'électricité et de l'électronique. A cet effet, l’IEC – entre autres activités – publie des Normes
internationales, des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au
public (PAS) et des Guides (ci-après dénommés "Publication(s) de l’IEC"). Leur élaboration est confiée à des
comités d'études, aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les
organisations internationales, gouvernementales et non gouvernementales, en liaison avec l’IEC, participent
également aux travaux. L’IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO),
selon des conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l’IEC concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l’IEC
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de l’IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l’IEC. Tous les efforts raisonnables sont entrepris afin que l’IEC
s'assure de l'exactitude du contenu technique de ses publications; l’IEC ne peut pas être tenue responsable de
l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de l’IEC s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l’IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l’IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) L’IEC elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de l’IEC. L’IEC n'est responsable d'aucun des services effectués par les organismes de certification
indépendants.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à l’IEC, à ses administrateurs, employés, auxiliaires ou
mandataires, y compris ses experts particuliers et les membres de ses comités d'études et
