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

Der vorliegende europäische Norm-Entwurf
3 legt Verfahren fest, mit denen in Abwasser- und Regenwasserinstallationen entstandener Luft- und Körper-schall unter Laborbedingungen gemessen werden kann;
3 legt die Angabe der Ergebnisse fest.
Er ist auf Abwasser-Rohrleitungssysteme und deren Teile, jedoch nicht auf die eigentlichen Abwasserquellen, z. B. Waschräume, Toiletten und Badewannen, anwendbar. Er ist auf Rohre mit natürlicher Lüftung anwendbar, die aus jedem üblichen Material bestehen können und die üblichen Durchmesser haben.
Die erhaltenen Ergebnisse können für den Vergleich von Produkten und Werkstoffen verwendet werden. Er kann zur Einschätzung des Verhaltens von Abwassersystemen in einem Gebäude unter bestimmten Bedingungen dienen. Diese Norm liefert jedoch kein normiertes Verfahren zur Berechnung der akustischen Eigenschaften solcher Installationen in einem Gebäude.

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

Le présent projet de Norme européenne :
3   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 ;
3   définit l'expression des résultats.
Il s'applique aux systemes de canalisations d'évacuation des eaux usées et aux éléments associés, a 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 diametres couramment utilisés (jusqu'a 150 mm).
Les résultats obtenus peuvent etre utilisés pour comparer les produits et les matériaux. Cela peut servir a apprécier le comportement des systemes 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.

EN 14366:2004 (E) 4 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.

EN 14366:2004 (E) 8 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’s). The specimen is then disconnected from the test wall and the water system operated in order to measure the background noise. The values L’s are then corrected for background noise giving the values Ls. These values are then normalized (see 9.5) to an equivalent absorption area of 10 m2 using the measured reverberation time Tr of the receiving room giving the values Lsn. After the last step, the results are corrected for the difference in structural sensitivity between the test wall used and the reference wall (correction given in clause 9). 5.2 Airborne sound measurement (index a) The specimen is mounted on a test wall inside the test room (source room). Appropriate openings in the ceiling and in the floor are provided. A steady flow of tap water is applied. The sound in the test room, produced as airborne sound radiated directly from the object but also as structure-borne sound radiated by the wall is measured (L’t). The water flow is stopped in order to measure the background noise. The values L’t are then corrected for background noise giving the values Lt and normalized to an equivalent absorption area of 10 m2 using the measured reverberation time Te of the source room giving the values Ltn. Later in the progress of calculation the structure-borne contribution is subtracted giving the values Lan. 6 Equipment 6.1 Requirements for the frequency range of measurement Throughout this standard the frequency range is limited to the eighteen 1/3 octave bands with mid-frequencies from 100 Hz to 5 000 Hz. If additional information is required in the low frequency range, measurements at 1/3 octaves 50 Hz, 63 Hz and 80 Hz can be made; guidance for such additional measurements is given in EN ISO 140-3:1995 Annex F. 6.2 Requirements for the acoustic equipment The equipment shall comply with the requirements of EN ISO 140-3:1995 clause 4. 6.3 Requirements for the
