Acoustic properties of building elements and of buildings - Laboratory measurement of the impact sound insulation of stairs and stair isolating elements
This document specifies procedures to measure in laboratory the impact sound level reduction of isolated heavy landings connected to a heavy wall, isolated heavy flights of stairs connected to a heavy landing, lower or upper floor, and lightweight stairs connected to a heavy wall, lower or upper floor.
This document also considers the characterization of isolating elements for heavy landings or heavy flights of stairs in terms of an insertion loss expressed as an impact sound level difference. The corresponding procedure is given in a normative annex (Annex A), separated from the other procedures for the sake of clarity.
The tests are performed in defined test configurations and the test results are firstly restricted to the test configurations as described in the test report. The data can be used for comparing the performance of products and as input for EN ISO 12354-2:2017, Annex F, to calculate the sound pressure levels produced by the same stairs and isolating elements when installed in buildings.

Propriétés acoustiques des éléments de construction et des bâtiments - Mesurage en laboratoire de l’isolation au bruit de choc des escaliers et des éléments isolants d’escalier
Le présent document spécifie les modes opératoires pour le mesurage en laboratoire de la réduction du niveau de bruit de choc des paliers lourds isolés fixés à un mur lourd, des volées d’escalier lourd isolées fixées à un palier, un plancher inférieur ou supérieur, et des escaliers légers fixés à un mur, un plancher inférieur ou supérieur lourd.
Le présent document traite également de la caractérisation des éléments isolants pour les paliers lourds ou les volées d’escalier lourd concernant une perte par insertion exprimée comme une différence de niveau de bruit de choc. Le mode opératoire correspondant est donné dans une annexe normative (Annexe A), séparée des autres modes opératoires pour plus de clarté.
Les essais sont effectués dans des configurations d’essai définies et les résultats d’essai sont d’abord limités aux configurations d’essai telles que décrites dans le rapport d’essai. Les données peuvent être utilisées pour comparer les performances des produits et en tant que données d’entrée pour l’EN ISO 12354-2:2017, Annexe F, afin de calculer les niveaux de pression acoustique produits par les mêmes escaliers et éléments isolants lorsqu’ils sont installés dans des bâtiments.

Introduction
The procedure for characterizing the impact sound performance of stairs comes from
EN ISO 12354-2:2017, Annex F, where the performance is expressed, like the performance of any floor
covering, as a reduction of impact sound pressure level. This quantity allows the product comparison of
stairs and stair isolating elements and predicting the impact sound of stairs in buildings using
EN ISO 12354-2.---------------------- Page: 7 ----------------------

1 Scope
This document defines procedures to measure in laboratory the impact sound level reduction of isolated
heavy landings connected to a heavy wall, isolated heavy flights of stairs connected to a heavy landing,
floor or ceiling, and lightweight stairs connected to a heavy wall, floor or ceiling.
This document also considers the characterization of isolating elements for heavy landings or heavy
flights of stairs in terms of an insertion loss expressed as an impact sound level difference. The
corresponding procedure is given in a normative annex (Annex A), separated from the other procedures
for the sake of clarity.The tests are performed in defined test configurations and the test results are firstly restricted to the test
configurations as described in the test report. The data can be used for comparing the performance of
products and as input for EN ISO 12354-2:2017, Annex F, to calculate the sound pressure levels produced
by the same stairs and isolating elements when installed in buildings.2 Normative references

1 Reference wall
2 Isolated reference landing
3 Lightweight stair
Figure 1 — Procedure for measuring the impact sound pressure level reduction of isolated
heavy landings (top) or lightweight stairs (bottom) connected to walls; the arrow represents the
excitation sourceThe principle of the method (Figure 1) consists of measuring in the receiving room the normalized impact
sound pressure level Ln0,wall of the bare wall, and then the impact sound pressure level Ln,landing of the
of the lightweight stair connected to the wall.isolated landing or the impact sound pressure level Ln,stair
The impact sound pressure level reduction is obtained as:
ΔL = L – L
landing n0,wall n,landing
ΔL = L – L
stair n0,wall n,stair
For measuring the impact sound of the isolated landing or the lightweight stair, the ISO tapping machine
is used as excitation source; for measuring the impact sound of the wall, the indirect method defined in
prEN 12354-5:2022, Annex B, is used, which requires an instrumented impact hammer or an
electromagnetic shaker as excitation source.---------------------- Page: 14 ----------------------
