Laboratory measurement of airborne and structure-borne sound from service equipment - Part 1: Application rules for waste water installations

This document characterizes waste water or rain water piping systems as airborne sound source and structure-borne sound source using the same method as the one described in EN 15657 for characterizing building service equipment. It therefore applies to equipment installed in any type of buildings (heavy or lightweight).
This document:
-   specifies laboratory measuring methods for determining the input data required for both comparing products and materials, and predicting sound levels in buildings using EN 12354 5. These input quantities are the piping system sound power level for airborne sound and three quantities for structure-borne sound (piping system free velocity, blocked force and mobility), from which the piping system installed power, source input for EN 12354 5, is determined;
-   specifies the method for the measurement of the equipment airborne sound power;
-   only considers piping systems connected to one supporting building element in a first step;
NOTE   Simultaneous structure-borne transmissions to wall and floor are more difficult to handle. In the configurations proposed in this document, the piping system is only connected to one supporting element and mechanically decoupled from the other elements.
-   includes configurations of vertical pipes with offset (deviated horizontally) connected to walls and horizontal pipes connected to ceilings, for which the measuring method is the same as the one defined for straight vertical pipes connected to walls. These complementary configurations are described in (normative) Annex A;
-   specifies laboratory test procedures for determining the performance of mitigation measures such as pipe enclosures (technical shaft) and pipe lining. The corresponding specifications are given in (normative) Annex B;
-   defines the expression of the results for use in comparing products and materials and for use as input data for prediction; however, the Single Number Quantities used to compare products cannot be used as a prediction or proof of compliance with requirements in a building;
-   indicates a method to transform the quantities measured according to EN 14366:2004+A1:2019, to the quantities used in this document; however, the calculated values cannot be used as certified values obtained by test, but only for comparison with new tests. This method is given in (informative) Annex C.
This document is applicable to waste water piping systems and parts thereof, but not to the actual sources of waste water, e.g. lavatories, toilets and bathtubs or any active units, which are considered separately in EN 12354 5 and are characterized separately. It applies to pipes with natural ventilation and made of any common material in commonly used diameters (up to 150 mm).

Dieses Dokument:
-   legt Prüfstandsmessverfahren für die Bestimmung der Eingangsdaten fest, die sowohl für den Vergleich von Produkten und Werkstoffen als auch zur Prognostizierung von Schallpegeln in Gebäuden nach EN 12354 5 erforderlich sind. Diese Eingangsdaten sind der Schallleistungspegel des Rohrleitungs¬systems für Luftschall und drei Größen für den Körperschall [die freie Schnelle im Rohrleitungssystem, die Kurzschlusskraft (en: blocked force) und die Admittanz], aus denen sich die installierte Leistung des Rohrleitungssystems bestimmen lässt, die eine auf die Quelle bezogene Eingabe für EN 12354 5 darstellt;
-   legt das Verfahren für die Messung der Luftschallleistung der Ausrüstung fest;
-   berücksichtigt im ersten Schritt nur solche Rohrleitungssysteme, die mit einem tragenden Bauteil verbunden sind;
ANMERKUNG   Gleichzeitige Körperschallübertragungen auf Wand und Boden sind schwieriger zu handhaben. Bei den in diesem Dokument vorgeschlagenen Konfigurationen ist das Rohrleitungssystem mit nur einem tragenden Bauteil verbunden und von den anderen Bauteilen mechanisch entkoppelt.
-   enthält Konfigurationen von vertikalen, mit einem (Horizontal-)Versatz wandmontierten Rohren und von horizontalen deckenmontierten Rohren, bei denen das gleiche Messverfahren angewendet wird, wie bei vertikal wandmontierten, geraden Rohren. Diese ergänzenden Konfigurationen sind im (normativen) Anhang A beschrieben;
-   legt Laborprüfverfahren für die Bestimmung der Leistung der Minderungsmaßnahmen, wie z. B. von Rohreinhausungen (Haustechnikkanal) und Rohrverkleidungen, fest. Die entsprechenden Spezifika-tionen sind im (normativen) Anhang B angegeben;
-   legt die Angabe der Ergebnisse für die Verwendung beim Vergleich von Produkten und Werkstoffen und für die Verwendung als Eingangsdaten für die Vorhersage fest; jedoch können die für den Vergleich von Produkten verwendeten Einzahlangaben nicht zur Vorhersage oder als Nachweis der Einhaltung von Anforderungen in einem Gebäude genutzt werden;
-   zeigt ein Verfahren zur Umrechnung der nach EN 14366:2004+A1:2019 gemessenen Größen in die in diesem Dokument verwendeten Größen auf; allerdings können die berechneten Werte nicht als mittels Prüfungen gewonnene zertifizierte Werte genutzt werden, sondern nur für den Vergleich mit neuen Prüfungen. Dieses Verfahren ist im (informativen) Anhang C angegeben.
Dieses Dokument ist für Abwasser Rohrleitungssysteme und deren Teile, nicht jedoch für die eigentlichen Abwasserquellen, z. B. Waschräume, Toiletten und Badewannen oder alle aktiven Elemente anwendbar; diese werden in EN 12354 5 gesondert betrachtet und charakterisiert. Es ist für Rohre mit natürlicher Lüftung aus jedem üblichen Werkstoff und mit üblichen Durchmessern (bis 160 mm) anwendbar.

Mesurage en laboratoire des bruits aériens et structuraux des équipements techniques - Partie 1 : Règles d’application aux installations d’évacuation des eaux usées

Le présent document caractérise les systèmes de canalisations d’évacuation des eaux usées ou des eaux pluviales comme source de bruit aérien et source de bruit structural, en utilisant la même méthode que celle décrite dans l’EN 15657 pour caractériser les équipements techniques des bâtiments. Il s’applique donc aux équipements installés dans tout type de bâtiments (lourds ou légers).
Le présent document :
-   spécifie des méthodes de mesurage en laboratoire qui permettent de déterminer les données d’entrée requises pour comparer les produits et les matériaux, ainsi que pour prédire les niveaux de bruit dans les bâtiments en utilisant l’EN 12354 5. Les grandeurs d’entrée sont le niveau de puissance acoustique du système de canalisations pour le bruit aérien et trois grandeurs relatives au bruit structural (vitesse libre, force bloquée et mobilité du système de canalisations), à partir desquelles est déterminée la puissance installée du système de canalisations, qui constitue la donnée d’entrée relative à la source pour l’EN 12354 5 ;
-   spécifie la méthode de mesurage de la puissance acoustique des équipements ;
-   considère uniquement les systèmes de canalisations fixés à un seul élément support lors d’une première étape ;
NOTE   Les transmissions structurales simultanées au mur et au plancher sont plus difficiles à traiter. Dans les configurations proposées dans le présent document, le système de canalisations n’est fixé qu’à un seul élément support et est mécaniquement séparé des autres éléments.
-   comprend des configurations de canalisations verticales avec décalage (déviées horizontalement) fixées à des murs et de canalisations horizontales fixées à des parois horizontales, pour lesquelles la méthode de mesurage est la même que celle définie pour les canalisations verticales droites fixées à des murs. Ces configurations complémentaires sont décrites dans l’Annexe A (normative) ;
-   spécifie des modes opératoires d’essai en laboratoire pour déterminer les performances des dispositifs d’atténuation tels que les encoffrements (gaine technique) et les revêtements de canalisations. Les spécifications correspondantes sont détaillées dans l’Annexe B (normative) ;
-   définit l’expression des résultats à utiliser pour comparer des produits et des matériaux et ceux à utiliser comme données d’entrée à des fins de prédiction ; les valeurs uniques utilisées pour comparer des produits ne peuvent pas être utilisées pour prédire ou prouver la conformité d’un bâtiment à des exigences ;
-   indique une méthode pour transformer les grandeurs mesurées conformément à l’EN 14366:2004+A1:2019, en grandeurs utilisées dans le présent document ; cependant, les valeurs calculées ne peuvent pas être utilisées comme des valeurs certifiées obtenues par essai, mais uniquement à des fins de comparaison avec de nouveaux essais. Cette méthode est décrite dans l’Annexe C (informative).
Le présent document s’applique aux systèmes de canalisations d’évacuation des eaux usées et aux éléments associés, mais pas aux sources d’eaux usées (cuvettes de WC, toilettes et baignoires ou tout équipement actif, par exemple), qui sont examinées séparément dans l’EN 12354 5 et font l’objet d’une caractérisation séparée. Il s’applique aux canalisations avec aération naturelle, réalisées en un matériau courant quelconque dans des diamètres couramment utilisés (jusqu’à 160 mm).

Overview

EN 14366-1:2023 (CEN) - Laboratory measurement of airborne and structure-borne sound from service equipment, Part 1: Application rules for waste water installations - defines laboratory methods to characterize waste water and rain water piping systems as airborne sound and structure-borne sound sources. The 2023 revision aligns the characterization approach with EN 15657 (building service equipment), updates test configurations (vertical, offset and horizontal pipes), and adds procedures for assessing mitigation measures such as pipe enclosures (technical shafts) and pipe lining. It applies to common pipe materials and diameters (commonly cited up to 150 mm; some internal references indicate up to 160 mm) and excludes active fixtures (lavatories, toilets, bathtubs), which are treated separately.

Key topics and requirements

• Measured quantities:
  • Piping system sound power level (airborne sound)
  • Three structure-borne descriptors: free velocity, blocked force, and mobility
  • From these, the installed power / source input for EN 12354-5 prediction is derived
• Measurement methods:
  • Laboratory airborne sound power measurement in a test room
  • Vibration-based structure-borne characterization (reduces need for multiple rooms)
  • Calibration and equipment requirements for acoustic, hydraulic and vibration instrumentation
• Test configurations:
  • Standard straight vertical pipe connected to a wall
  • Complementary configurations: vertical pipes with offset and horizontal pipes connected to ceilings (Annex A - normative)
  • Specimens mechanically decoupled from non-supporting building elements (single supporting element assumption)
• Mitigation assessment:
  • Normative test procedures for pipe enclosures and pipe lining performance (Annex B)
  • Single Number Descriptors for product comparison (note: these SNQs are for comparison only and not for predictive compliance)
• Transition guidance:
  • Informative Annex C explains transformation from EN 14366:2004+A1:2019 measurement results to the new quantities

Applications and who uses it

EN 14366-1:2023 is aimed at professionals working in building acoustics and plumbing noise control:

• Acoustic consultants and engineers predicting noise in buildings using EN 12354-5
• Test laboratories and manufacturers producing acoustic data for product comparison and datasheets
• Building designers and specifiers, mechanical services designers, and façade/partition engineers assessing sound performance
• Regulatory bodies and certification programs requiring standardized laboratory characterization of piping systems

Introduction
Noise from waste water installations is generated by the flow 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 or hidden by an enclosure. It seems advisable, therefore, to define
measuring methods for both structure-borne and airborne sound. The first standard on laboratory sound
measurements of waste water installations (EN 14366) was published in 2004. The present standard is
a revision of EN 14366:2004+A1:2019, and is still focused on laboratory characterization of waste water
installations for both airborne and structure-borne sound, but now uses the same characterization
methods as for building service equipment, i.e. EN 15657. In particular, structure-borne sound is now
characterized by vibration measurements and therefore only one test room is required in the standard
for airborne sound measurement.
NOTE The room is particularly necessary to keep the former standard configuration, where the piping system
mounting conditions in a room are similar to the ones in buildings. A method based on acoustical intensity could be
used with no room at all; such a method is not precisely defined and validated yet, but could be standardized in a
future revision of the standard.
Important noise sources are bends after vertical sections, bends for pipe deviation, but also
discontinuities, e.g. inlets, couplings and sleeves. The revised standard keeps the standard configuration
specified in the former one (straight pipe system connected to walls), but also considers vertically
deviated pipes connected to walls and horizontal pipes connected to ceilings.
In addition, the revised standard includes measuring the performance of mitigation measures such as
pipe enclosures (technical shaft) and pipe lining.
The title and numbering of the revised document have been changed, now opened to other application
standards for equipment systems such as water supply installations.
1 Scope
This document characterizes waste water or rain water piping systems as airborne sound source and
structure-borne sound source using the same method as the one described in EN 15657 for
characterizing building service equipment. It therefore applies to equipment installed in any type of
buildings (heavy or lightweight).
This document:
— specifies laboratory measuring methods for determining the input data required for both comparing
products and materials, and predicting sound levels in buildings using EN 12354-5. These input
quantities are the piping system sound power level for airborne sound and three quantities for
structure-borne sound (piping system free velocity, blocked force and mobility), from which the
piping system installed power, source input for EN 12354-5, is determined;
— specifies the method for the measurement of the equipment airborne sound power;
— only considers piping systems connected to one supporting building element in a first step;
NOTE Simultaneous structure-borne transmissions to wall and floor are more difficult to handle. In the
configurations proposed in this document, the piping system is only connected to one supporting element and
mechanically decoupled from the other elements.
— includes configurations of vertical pipes with offset (deviated horizontally) connected to walls and
horizontal pipes connected to ceilings, for which the measuring method is the same as the one
defined for straight vertical pipes connected to walls. These complementary configurations are
described in (normative) Annex A;
— specifies laboratory test procedures for determining the performance of mitigation measures such
as pipe enclosures (technical shaft) and pipe lining. The corresponding specifications are given in
(normative) Annex B;
— defines the expression of the results for use in comparing products and materials and for use as input
data for prediction; however, the Single Number Quantities used to compare products cannot be used
as a prediction or proof of compliance with requirements in a building;
— indicates a method to transform the quantities measured according to EN 14366:2004+A1:2019, to
the quantities used in this document; however, the calculated values cannot be used as certified
values obtained by test, but only for comparison with new tests. This method is given in (informative)
Annex C.
This document is applicable to waste water piping systems and parts thereof, but not to the actual sources
of waste water, e.g. lavatories, toilets and bathtubs or any active units, which are considered separately
in EN 12354-5 and are characterized separately. It applies to pipes with natural ventilation and made of
any common material in commonly used diameters (up to 160 mm).

5 Measuring method
5.1 Airborne sound measurements
No airborne sound power measurement method is defined in EN 15657, which refers to EN ISO 3740
to 3747 [2–4]. However, measurements in the present standard are very particular, involving all together
small rooms (at least 50 m ), low frequencies (range down to one-third octave 50 Hz) and both stationary
and non-stationary sources; consequently, they are fully described here.
The specimen is mounted on the test wall inside the test room (see Figure 2). Appropriate openings in
the upper and lower floors are provided. A steady flow of tap water is applied. The total sound power
level L in the test room, produced as airborne sound radiated directly from the specimen but also
Wa,total
as structure-borne sound radiated by the test wall (and the other walls with smaller contributions) is
measured according to the following method:
— the specimen shall be mounted in accordance with Clause 8;
— the following values are measured in one-third octave bands and according to EN ISO 10140-4: (i)
the sound pressure level in the room with the source operating, (ii) the sound pressure level of the
back-ground noise (water flow stopped) and (iii) the reverberation time T of the room;
r
— the measured level is corrected for background noise according to EN ISO 10140-4 (leading to
L ) and normalized to an equivalent absorption area of 10 m (leading to L ):

NOTE In this document, the power levels are expressed in dB ref. 10 Watt.
5.2 Structure borne sound measurements
5.2.1 General
The test wall (see 7.1.2) shall be a low mobility wall compared to the specimen mobility, as specified in
EN 15657:2017, C.4. To check the above assumption, the following applicability test can be performed:
with the wall mechanically excited by a calibrated source according to 5.2.2, the velocity is measured on
the wall at contact points with the specimen and without (before installing the specimen), and normalized
to the excitation expressed in terms of installed power; a difference of less than 3 dB between the two
normalized velocity levels obtained at each fixing point indicates a low mobility wall compared to the
source mobility.
The required structure-borne sound measurements can be performed in two steps: a calibration of the
test facilities (see 5.2.2), which can be done once and checked periodically, and the actual testing of the
specimen considered (see 5.2.3 and 5.2.4).
5.2.2 Calibration of the test facilities
The test wall is mechanically excited using a calibrated vibration source (instrumented hammer or shaker
as suggested in EN ISO 10848-1) successively applied on the side opposite to the test room at each contact
j between the specimen and the test wall.
The following three quantities are then measured for each excitation location:
— the installed power level L of the calibrated vibration source determined according to
Ws,cal,j
EN ISO 10848-1,
— the sound power level L radiated with the calibrated source (operating), measured in the
Wa,struc,cal, j
test room as in 5.1 and
— the space average vibration velocity of the test wall L measured according to EN 15657:2017,

C.3.
−9
NOTE In this document, the velocity levels are expressed in dB ref. 10 m/s.
The calibrated source shall be powerful enough so that L is well above the background noise.
v ,cal,j
There should be no significant difference if the above measurements are performed with or without the
specimen connected to the wall.

5.2.3 Indirect procedures for testing the specimen
5.2.3.1 Blocked force measurements
The piping system single equivalent blocked force is indirectly obtained using the power substitution
method according to EN 15657:2017, Annex C as follows:
a) with the specimen mounted on the test wall inside the test room, a steady flow of tap water is applied
and the space average vibration velocity level of the test wall L is measured according to
v
EN 15657:2017, C.3. The water flow is stopped in order to measure the background noise and L
v
is corrected for background noise.
The contribution of the airborne excitation of the test wall due to the pipe near field is taken into
account when measuring the blocked force; this contribution is indeed not taken into account
anywhere else and should be included. Note that, in the 2004 version of the standard, this
contribution was subtracted.
b) The specimen installed power level L is calculated from the installed power levels of the calibrated
Ws
vibration source L (see 5.2.2) applied successively at the contacts j corrected for the difference
Ws,cal, j
in velocity level of the test wall between the two excitation cases (using respectively the specimen
and the calibrated vibration source):

c) direct measurements of the test wall point mobility Y are performed at each contact j between
R,low,j
the specimen and the test wall according to EN 15657:2017, 6.2, from which the wall real part of the
single equivalent mobility is calculated as:

NOTE The test wall can be pre-calibrated as in 5.2.2 by measuring the wall point mobility on a grid of points
regularly distributed over the wall and by using in Formula (3) the two points on the grid the closest to the
specimen contacts.
There should be no significant difference if the mobility measurements are performed with or
without the specimen connected to the wall.

5.2.3.2 Structure-borne contribution to the specimen total sound power
The structure-borne sound power L radiated in the test room with the test wall excited by the
Wa,struc
specimen, is obtained indirectly using the (installed) power substitution method: L is obtained
Wa,struc
from the sound power levels L radiated by the calibrated source applied successively at the

5.2.4 Specimen free velocity direct measurement
The specimen free velocity is directly measured at the piping system two fixing points according to
EN 15657:2017, 6.1, the piping system being disconnected from the test wall. Measurements are located
on clamps as shown in Figure 1, either rigidly or elastically fixed to pipe. The measurements are corrected
for background noise if any.

According to EN ISO 10140-5.
8 Test specimen
8.1 Geometry
8.1.1 Components
The objects tested according to this document are parts of a wastewater installation with a single path of
the water flow and consist of:
— an inlet, part of the test object according to Figure 2;
— any combination of straight pipes, tees, bends, joints and inlets, mounted with clamps on the test
wall;
— a basement bend of totally approximately 90° angle, being part of the specimen.
8.1.2 Falling height h
The falling height h shall be in the range from 5,8 m to 7,5 m, measured between the inlet point and the
impact point. (Figure 3). The inlet point is given as the intersection of the axis of the inlet tube with the
axis of the vertical pipe; the impact point is defined by the intersection of the vertical pipe axis with the
wall of the basement bend.
8.1.3 Standard configuration
For comparison purposes, the following standard configuration is used:
The standard configuration consists of a straight vertical pipe with an inlet tee within the measuring room
and an inlet tee above the test room, both closed by an accessory of the manufacturer. In the standard
configuration the basement bend is made of two 45° bends of the same material as the test object. The
horizontal evacuation pipe shall be supported without connection to the test room floor and its slope
similar as in buildings.

8.1.4 Other configurations considered
The scope of this document includes configurations of vertical pipes with offset (deviated horizontally)
connected to walls and horizontal pipes connected to floors, for which the measuring method is the same
as the one use for the standard configuration. These configurations are described in Annex A (normative
annex).
8.2 Mounting of the specimen
8.2.1 General
The mounting is performed exactly according to the instructions given by the manufacturer or distributor
of the waste water installation. It shall be described in full detail in the test report.
The test object is mounted in the restricted area of the test wall, as specified in Figure 4. At least one fixing
point shall be used to fasten the system to the test wall. No further restrictions are made concerning the
location of clamps, clips and other fixing devices.
The mandatory basement bend shall be mounted below the floor of the test room, at a distance of
(15 ± 5) cm from the floor (see Figure 3). It shall be fixed rigidly but avoiding any direct transmission of
structure-borne sound to the test room. Above the test room, the upper installation is fixed, avoiding also
any direct transmission of structure-borne sound to the test room.
8.2.2 Requirements for airborne sound measurement
The air gaps between tube and floor in the entrance and exit openings have to be carefully filled with
porous absorbent material and covered with plastic sealant in order to prevent any airborne sound from
the outside influencing the measurement. The seal shall remain sufficiently flexible to avoid mechanical
clamping of the pipe so that the structure borne sound contribution of the lower and upper floors can be
assumed negligible.
8.2.3 Requirements for the standard configuration
Two clamps shall be used to fasten the system to the test wall. If not otherwise specified by the
manufacturer, metal sleeves shall be used. Clamp type and locations shall be described in the test report.
The weight of the system shall be secured by at least one of the two clamps.

9 Expression of the results
9.1 General
This document defines the expression of the results for use in comparing products and materials in terms
of performance, for which single number quantities are required, and for use in predicting service
equipment sound levels in buildings, for which one-third octave spectra are required as input data for
the prediction method being defined in EN 12354-5. These quantities are defined in this clause and
summarized in Table 3 below.
9.2 For use in comparing products and materials
9.2.1 General
When considering service equipment sound in buildings and choosing products, practitioners should
differentiate airborne sound performances from structure-borne sound performances and should be
aware, that the structure-borne sound performances greatly depend on the type of building on which the
equipment is mounted: heavy buildings (with elements of type A as defined in EN ISO 10848-1) usually
with low mobility elements or lightweight buildings (with elements of type B). As a result, it is useful to
consider the following three quantities for comparing products:
— for airborne sound, the airborne sound power, which can be A-weighted, shall be used, expressed in
terms of single number value (see 9.2.2);
— for structure-borne sound, there is no standard defining the quantity and procedure for calculating
single number values in order to compare sources characterized according to EN 15657 in general
and EN 14366-1 in particular. The source input quantities for prediction (blocked force level for low
mobility receiver and installed power for the other cases) cannot be A-weighted and the apparent
structure-borne sound pressure level L' , generated in any building structures, only quantity that
ne,s
could be A-weighted, depends on the transmission paths to the receiving room. Reference building
structures should therefore be standardized, from which the apparent sound pressure level
generated by any source could be calculated using EN 12354-5 and expressed as single number
value. Since such reference building structures don’t exist yet, it is suggested for the time being to
use the building configurations given in EN 12354-5:2023, G.4, and take the A-weighted sound
pressure level obtained as an example of single number value (see 9.2.3).
The Single Number Quantities can only be used to compare products but not at all as a prediction or proof
of compliance with requirements in a building.
9.2.2 Single number descriptor for airborne sound
The A-weighted single number descriptor is calculated from the measured airborne sound power level
spectrum as:

9.2.3 Single number descriptor for structure-borne sound
Two examples of building structures are specially given in EN 12354-5:2023, G.4 for application to
products characterized using EN 14366-1: one example with a low mobility receiver in a heavy building
and the other in a lightweight building.
— for the heavy building with low mobility receiver (G.4.2), the performance of the building is given in
terms of apparent impact sound pressure level L' obtained when the equipment is replaced by the
n
tapping machine. Then the apparent structure-borne sound pressure level generated by the
equipment considered shall be calculated using the prediction method defined in EN 12354-5:2023,
5.3.3 and A-weighted using the same procedure as in 9.2.2. The only input data required is the source
single equivalent blocked force level.
— for lightweight structures (G.4.3), the performance of the building is given in terms of apparent unit
power sound pressure level obtained when the equipment is replaced by a unit power source;

the single equivalent mobility magnitude of the receiver, required for calculating the source installed

equipment considered shall be calculated using the prediction method defined in EN 12354-5:2023,
5.3.2.2 and A-weighted using the same procedure as in 9.2.2. The input data required is the source
installed power level, which shall be calculated according to EN 12354-5:2023, 5.3.2.1 from the
source single equivalent blocked force or free velocity level and the source single equivalent mobility
magnitude.
