Acoustics - Determination of sound insulation performances of enclosures - Part 1: Measurements under laboratory conditions (for declaration purposes) (ISO 11546-1:1995)

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

Akustik - Bestimmung der Schalldämmung von Schallschutzkapseln - Teil 1: Messungen unter Laborbedingungen (zum Zweck der Kennzeichnung) (ISO 11546-1:1995)

Dieser Teil von ISO 11546 beschreibt Laborverfahren für die Bestimmung der Schalldämmung (Einfügungs-dämm-Maß) kleiner Schallschutzkapseln für Maschinen.
Er gilt nur für eine vollständige Schallschutzkapsel und nicht für die einzelnen Wände, aus denen sie hergestellt wurde.
ANMERKUNG 1   Die Schalldämmungen der Kapselteile, wie z. B. der Wandelemente, Türen, Fenster, Schalldämpfer usw., sollten nach anderen, diese betreffenden Normen gemessen werden.
ANMERKUNG 2   Ähnliche Normen betreffen die Messung der Geräuschminderung von Schallschutzkapseln im Einsatzfall (ISO 11546 2) und von Kabinen (ISO 11957).
Die in diesem Teil von ISO 11546 beschriebenen Messverfahren beruhen auf den Internationalen Normen der Reihen ISO 3740, ISO 9614 und ISO 11200 (siehe Tabelle 1). In Abhängigkeit vom gewählten Verfahren wird die Schalldämmung der Schallschutzkapsel (Einfügungsdämm Maß) als Schallleistungs  oder Schalldruck-pegelminderung bestimmt. Es werden Verfahren beschrieben, bei denen die Kapsel die tatsächliche Schall-quelle (Maschine) umschließt. Wo diese Verfahren nicht anwendbar sind, kann alternativ ein Reziprozitäts-verfahren (siehe Begriffe 3.11 und 7.2) oder eine Ersatzschallquelle angewendet werden.
Dieser Teil von ISO 11546 ist uneingeschränkt anwendbar auf freistehende Schallschutzkapseln mit einem Volumen von weniger als 2 m3. Wird die tatsächliche Schallquelle verwendet, können Schallschutzkapseln mit Volumina von mehr als 2 m3 gemessen werden, wenn die Anforderungen der in Bezug genommenen Norm hinsichtlich des höchstzulässigen Volumens erfüllt sind. Das Verfahren unter Benutzung der tatsächlichen Schallquelle kann auf beliebig konstruierte Schallschutzkapseln, z. B. integrierte Schallschutzkapseln, angewendet werden.
Wenn das Reziprozitätsverfahren oder das Verfahren mit Ersatzschallquelle benutzt wird, ist das höchst-zulässige Volumen der Schallschutzkapsel auf 2 m3 begrenzt. Diese Verfahren sind nicht auf hautenge Schallschutzkapseln anwendbar.

Acoustique - Détermination de l'isolement acoustique des encoffrements - Partie 1: Mesurages dans des conditions de laboratoire (aux fins de déclaration) (ISO 11546-1:1995)

La présente partie de l'ISO 11546 prescrit des méthodes de laboratoire pour la détermination de l'isolement acoustique (perte d'insertion) de petits 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 in situ (ISO 11546-2), 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 en recourant à une méthode de réciprocité (voir définition 3.11 et paragraphe 7.2) ou à une source sonore artificielle. La présente partie de l'ISO 11546 s'applique sans restriction à des encoffrements autoporteurs d'un volume inférieur à 2 m3. Si la source sonore réelle est utilisée, l'isolement acoustique d  848es encoffrements dont le volume dépasse 2 m peut être déterminé à condition de satisfaire aux exigences relatives au volume maximal autorisé par la norme utilisée. La méthode avec source sonore réelle est applicable à tous les types d'encoffrements, par exemple aux encoffrements fixés à la machine. Lorsque l'on recourt à la méthode de réciprocité ou à la méthode avec source sonore artificielle, le volume maximal de l'encoffrement est limi

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 11546-1 was prepared by Technical Committee
lSO/TC 43, Acoustics, Subcommittee SC 1, Noise.
ISO 11 546 consists of the following Parts, under the general title Aco IUS-
