Acoustics - Determination of sound insulation performances of enclosures - Part 2: Measurements in situ (for acceptance and verification purposes) (ISO 11546-2:1995)

Specifies in situ methods for the determination of the sound insulation performance of machine enclosures. Does apply to a total enclosure only.

Acoustique - Détermination de l'isolement acoustique des encoffrements - Partie 2: Mesurages sur site (aux fins d'acceptation et de vérification) (ISO 11546-2:1995)

La présente partie de l'ISO 11546 prescrit des méthodes de détermination in situ de l'isolement acoustique (perte d'insertion) d'encoffrements de machines. Elle s'applique uniquement à un encoffrement complet et non pas aux panneaux individuels qui le composent.  
NOTES 1 L'isolement acoustique des panneaux constitutifs d'encoffrements tels que: éléments de paroi, portes, fenêtres, silencieux, etc. devrait être mesuré suivant les normes appropriées. 2 Il existe des normes relatives à la détermination de l'isolement acoustique des encoffrements dans des conditions de laboratoire (ISO 11546-1), et des cabines (ISO 11957). Les méthodes de mesurage prescrites dans la présente partie de l'ISO 11546 sont basées sur les Normes internationales des séries ISO 3740, ISO 9614 et ISO 11200 (voir tableau 1). Suivant la méthode choisie, l'isolement acoustique de l'encoffrement (perte d'insertion) est exprimé en termes de réduction du niveau de puissance acoustique ou du niveau de pression acoustique. Les méthodes sont données pour des mesurages effectués lorsque l'encoffrement entoure la source sonore réelle (machine). Lorsque ces méthodes ne sont pas applicables, d'autres mesurages peuvent être effectués avec une source de bruit artificielle. De telles méthodes sont aussi décrites dans la présente partie de l'ISO 11546.

Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national Standards bodies (ISO member bodies). The work
of preparing International Standards is normally carried out through ISO
technical committees. Esch member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 115462 was prepared by Technical Committee
lSO/TC 43, Acoustics, Subcommittee SC 1, Noise.
ISO 11546 consists of the following Parts, under the general title Acous-
tks - Determination of Sound insulation performances of enclosures:
- Part 7: Measuremen ts under laboratory conditions (for declaration
purposes)
- Part 2: Measurements in situ (for acceptance and verification pur-
poses)
Annex A forms an integral part of this part of ISO 11546. Annexes B, C,
D and E are for information only.
