Akustik - Angabe und Nachprüfung von Geräuschemissionswerten von Maschinen und Geräten (ISO 4871:1996)
Diese Internationale Norm
⎯ gibt Hinweise zur Angabe von Geräuschemissionswerten,
⎯ beschreibt die akustischen Angaben und Produktinformationen, die in technischen Unterlagen für die
Zwecke der Geräuschemissionsangabe enthalten sein müssen und
⎯ legt ein Verfahren für die Nachprüfung der Geräuschemissionsangabe fest.
Sie ist für Maschinen und Geräte anwendbar.
Die für die Zwecke der Geräuschemissionsangabe zu verwendenden Werte sind entweder angegebene
Einzahl-Geräuschemissionswerte Ld oder angegebene Zweizahl-Geräuschemissionswerte L und K. L ist ein
direkt aus Messungen bestimmter Geräuschemissionswert, und K ist die mit diesen Messungen verbundene
Unsicherheit. Ld ist die Summe aus L und K und stellt eine Obergrenze dar, die von den Werten aus
wiederholten Messungen mit einer vorgegebenen Wahrscheinlichkeit nicht überschritten wird; Ld entspricht
dem angegebenen Wert oder Kennzeichnungswert Lc nach ISO 7574-1.
Die beiden Formen der Geräuschangabe sind Alternativen für die Darstellung des A-bewerteten
Schallleistungspegels LWA, des A-bewerteten Emissions-Schalldruckpegels an festgelegten Orten LpA und
des C-bewerteten Emissions-Spitzenschalldruckpegels an festgelegten Orten LpC,peak. Die Entscheidung
darüber, welche der beiden Darstellungsformen in einem bestimmten Fall verwendet wird, hängt von den zu
erfüllenden Anforderungen ab. Diese Auswahl wird in der zutreffenden Geräuschmessnorm getroffen; dort
finden sich auch Informationen zu den Werten von K.
Leitlinien zur Bestimmung anzugebender Geräuschemissionswerte sind in Anhang A enthalten.
Acoustique - Déclaration et vérification des valeurs d'émission sonore des machines et équipements (ISO 4871:1996)
La présente Norme internationale -- donne des informations sur la déclaration des valeurs d'émission sonore, -- décrit les informations acoustiques et celles concernant le produit à faire figurer dans les documents techniques à fin de déclaration de l'émission sonore, et -- spécifie la méthode à suivre pour vérifier les valeurs déclarées d'émission sonore. Elle s'applique aux machines et aux équipements. Les valeurs à utiliser pour la déclaration de l'émission sonore sont soit les valeurs déclarées combinées, Ld, soit les valeurs déclarées dissociées, L et K. L est une valeur d'émission sonore directement issue de mesurages et K est l'incertitude de mesure associée à ces mesurages. Ld est la somme de L et de K et représente une borne supérieure que des valeurs provenant de mesurages répétés ont, pour un niveau de confiance donné, peu de chances de dépasser. Ld correspond à la valeur annoncée ou étiquetée. Lc, dans l'ISO 7574-1. Les deux formes de déclaration constituent deux manières de représenter l'une ou l'ensemble des grandeurs suivantes: le niveau de puissance acoustique pondéré A, LWA, le niveau de pression acoustique d'émission pondéré A à des positions spécifi 450ées, LpA, le niveau de pression acoustique d'émission de crête pondéré C à des positions spécifiées, LpC,peak. Le choix d'une des deux formes dans un cas particulier donné dépend des exigences à remplir. Il est fait dans le code d'essai acoustique approprié, qui guide aussi sur les valeurs de K. Des recommandations pour déterminer les valeurs déclarées d'émission sonore sont données dans l'annexe A.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each 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. IS0
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 IS0 4871 was prepared by Technical Committee
lSO/TC 43, Acoustics, Subcommittee SC 1, Noise.
This second edition cancels and replaces the first edition
(IS0 4871 :I 984), which has been technically revised.

Introduction
Information on the acoustic noise emitted by machinery and equipment is
needed by users, planners, manufacturers and authorities. This infor-
mation is required for comparing the noise emitted by different products,
for assessing noise emissions against noise limits, for planning workplace
noise levels, as well as for checking noise reduction achievements, and
may be used for estimating requirements for workplace noise immission.
In order for machinery noise emission data to be useful, uniform methods
of measurement and declaration are necessary to achieve the following
purposes.
Measurement of noise emission
a)
The IS0 3740 series specifies methods for determining the sound
power levels of noise sources from sound pressure level measure-
ments; the IS0 9614 series specifies methods for determining the
sound power levels from sound intensity level measurements; the
IS0 11200 series describes methods for determining emission sound
pressure levels at specified positions in the vicinity of machinery and
equipment. Many other standards give test codes for the measure-
ment of the noise emissions of individual types of machinery which
are based on these methods.
Determination of the noise emission value to be declared
b)
The IS0 7574 series gives methods for determining declared noise
emission values which are based primarily on the sound power levels
of noise sources. For a complete presentation of declared noise
emission values, it is necessary to state the sound pressure levels at
specified positions as well as the sound power level. Because of the
possible confusion in terminology with respect to sound pressure lev-
els used to define noise immission, the term “emission sound press-
ure level” is used in this International Standard.
Presentation of declared noise emission values
d
It is of prime importance to declare sound power levels. It is recog-
nized, however, that information on emission sound pressure levels is
sometimes required. It is recommended, therefore, that both kinds of
quantity be declared, unless otherwise specified. Noise emission
declarations can take the form of either a single-number or dual-
number presentation; the choice is made in the noise test code ap-
propriate to the particular family.
Verification of declared noise emission values
d
The IS0 7574 series gives procedures for the verification of a declared
noise emission value. In that International Standard, the procedures
are applied to verification of declared sound power levels. The pro-
cedures of this International Standard are applied to the verification of
@J IS0
IS0 4871:1996(E)
both sound power levels and emission sound pressure levels. The
information in this International Standard on the verification of declared
noise emission values may be used both by a buyer of equipment to
compare the relative noise levels of various products, and by a manu-
facturer as part of a statistical quality control programme.
Requirements on the declaration of noise emission values are given in
clause 4.
As the declaration of noise emission of machinery and equipment is the
responsibility solely of the manufacturer or supplier, guidelines concerning
the declaration are found in annex A.
Requirements on the presentation of declared noise emission values are
given in clause 5 and annex B, and those on verification are given in
clause 6 and annex C.
