Laboratory measurement of noise from waste water installations

This document:
-   specifies methods for the measurement of airborne and structure-borne sound produced in waste water and rain water installations under laboratory conditions;
-   defines the expression of the results.
It is applicable to waste water piping systems and parts thereof, but not to the actual sources of the wastewater, e.g. lavatories, toilets and bathtubs or any active units. It applies to pipes with natural ventilation and made of any common material in commonly used diameters (up to 150 mm).
The results obtained can be used for the comparison of products and materials. It may serve in estimating the behaviour of waste water systems in a building under certain conditions. Nevertheless, this standard does not provide a normalized procedure for calculating the acoustical properties of such installations in a building.

Messung der Geräusche von Abwasserinstallationen im Prüfstand

Dieses Dokument
—   legt Verfahren zur Messung von in Abwasser  und Regenwasserinstallationen entstandenem Luft  und Körperschall unter Laborbedingungen fest;
—   legt die Angabe der Ergebnisse fest.
Es gilt für Abwasser Rohrleitungssysteme und deren Teile, jedoch nicht für die eigentlichen Abwasser-quellen, z. B. Waschräume, Toiletten und Badewannen oder alle aktiven Elemente. Es gilt für Rohre mit natürlicher Lüftung aus jedem üblichen Material und mit üblichen Durchmessern (bis 150 mm).
!Die Prüfergebnisse können für den Vergleich von Produkten und Werkstoffen verwendet werden, können aber nicht als Werte verwendet werden, die vor Ort in Gebäuden erhalten wurden; Vor Ort Werte können mithilfe der in EN 12354 5:2009, 5.5, beschriebenen Verfahrensweise prognostiziert werden, die Labordaten in Felddaten umwandelt, indem angenommen wird, dass die Vor Ort Installation genau der im Prüfbericht beschriebenen entspricht."

Mesurage en laboratoire du bruit émis par les installations d'évacuation des eaux usées

Le présent projet de Norme européenne :
¾   spécifie des méthodes permettant de mesurer le bruit aérien et le bruit structural générés par des installations d'évacuation des eaux usées et des eaux de pluie dans des conditions de laboratoire ;
¾   définit l'expression des résultats.
Il s'applique aux systèmes de canalisations d'évacuation des eaux usées et aux éléments associés, à l'exclusion des véritables sources des eaux usées, par exemple les cuvettes de WC, les toilettes et les baignoires ou tout équipement actif. Il s'applique aux canalisations avec aération naturelle, réalisées en un matériau courant quelconque dans des diamètres couramment utilisés (jusqu'à 150 mm).
Les résultats obtenus peuvent être utilisés pour comparer les produits et les matériaux. Cela peut servir à apprécier le comportement des systèmes d'évacuation des eaux usées dans un bâtiment dans certaines conditions. Néanmoins, la présente norme ne fournit pas de mode opératoire normalisé pour le calcul des propriétés acoustiques de telles installations dans un bâtiment.

Laboratorijsko merjenje hrupa pri napeljavah za odpadno vodo

Ta dokument:
– določa metode za merjenje strukturnega zvoka in zvoka v zraku, ki nastaja v napeljavah za odpadno vodo in deževnico pri laboratorijskih pogojih;
– določa izražanje rezultatov.
Uporablja se za cevne sisteme za odpadno vodo in njihove dele, vendar ne za dejanske vire odpadne vode, npr. umivalnike, stranišča in kopalne kadi ali katere koli dejavne enote. Uporablja se za cevi z naravnim prezračevanjem, ki so izdelane iz običajnih materialov in imajo najpogosteje uporabljene premere (do 150 mm).
Pridobljene rezultate je mogoče uporabiti za primerjavo izdelkov in materialov. Uporablja se lahko pri ocenjevanju obnašanja sistemov za odpadno vodo v stavbi pod določenimi pogoji. Kljub temu ta standard ne podaja normiranega postopka za izračun akustičnih lastnosti takšnih napeljav v stavbi.

Introduction

Noise from wastewater installations is generated by the flow and fall of water in the piping system.

There are many different ways to install such systems in buildings, depending on national building

codes. They may be firmly cemented into walls and floors, fixed by clips in walls and covered slabs, or

hung exposed in the plenum above a suspended ceiling. It seems advisable, therefore, to define

measuring methods for both structure-borne and airborne sound.

Important noise sources are bends after vertical sections, but also discontinuities, e.g. inlets, couplings

and sleeves. Apart from that the noise impact on the inhabitants of a building strongly depends on the

material properties of the pipes, on the methods used in joining and fastening them and on the local

building practice.

1 Scope
This document:

— specifies methods for the measurement of airborne and structure-borne sound produced in waste

water and rain water installations under laboratory conditions;
— defines the expression of the results.

It is applicable to waste water piping systems and parts thereof, but not to the actual sources of the

wastewater, e.g. lavatories, toilets and bathtubs or any active units. It applies to pipes with natural

ventilation and made of any common material in commonly used diameters (up to 150 mm).

!The test results can be used for the comparison of products and materials, but cannot be used as

values obtained in buildings in situ; in situ values can be predicted using the procedure described in

EN 12354-5:2009, 5.5, which transfers laboratory data to field data, assuming the in-situ installation is

exactly the same as the one described in the test report."

5 Principle of the test method
5.1 Structure-borne sound measurements (index s)

The specimen is mounted outside the test room (receiving room), connected as in practice to the test

wall using the fixing material specified by the manufacturer of the system. A steady flow of tap water is

applied and the total sound transmitted into the test room is measured (L’ ). The specimen is then

disconnected from the test wall and the water system operated in order to measure the background

noise. The values L’ are then corrected for background noise giving the values L . These values are then

s s

normalized (see 9.5) to an equivalent absorption area of 10 m using the measured reverberation time

T of the receiving room giving the values L .
