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."
