Description (English):

ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one or several building components. This document considers only laboratory measurements. The measured quantities can be used to compare different products, or to express a requirement, or as input data for prediction methods, such as ISO 12354‑1 and ISO 12354‑2. However, the measured quantities Dn,f, Ln,f and Lne0,f only represent the performance with the dimensions for the test specimens described in this document. ISO 10848-2:2017 is referred to in ISO 10848‑1:2017, 4.5 as being a supporting part of the frame document. It applies to Type B elements as defined in ISO 10848‑1, such as suspended ceilings, access floors, light uninterrupted façades or floating floors. The transmission from one room to another can occur simultaneously through the test element and via the plenum (if any). For measurements made according to this document, the total sound transmission is determined and it is not possible to separate the two kinds of transmission.

Abstract

Overview

EN ISO 10848-2:2017 (CEN adoption of ISO 10848-2:2017) is a laboratory measurement standard for assessing flanking transmission of airborne, impact and building‑service equipment sound between adjoining rooms. It specifically addresses Type B elements (for example suspended ceilings, access floors, light uninterrupted façades, floating floors) in cases where the junction between elements has a small influence on transmission. The standard defines how to measure normalized quantities such as Dn,f, Ln,f and Lne0,f in a controlled test facility so results can be used for product comparison, specification limits or as input to prediction methods (e.g., ISO 12354‑1 and ISO 12354‑2).

Key Topics

Scope and applicability: Laboratory-only procedures for Type B flanking elements when junction influence is small; total sound transmission is measured (cannot separate plenum vs element paths).
Measured quantities: Normalized flanking level difference (Dn,f), normalized flanking impact sound pressure level (Ln,f) and normalized equipment sound pressure level (Lne0,f). Results are representative for the test specimen dimensions only.
Test arrangement: Requirements for the laboratory facility, construction and dimensions, dividing wall, plenum height/lining and installation methods for access floors, suspended ceilings, façades and partition walls.
Instrumentation & procedures: Guidance on measurement equipment, excitation (airborne and impact), shielding techniques and recommended test methods; includes expression of results, precision and reporting requirements.
Additional methods: Annex on using sound‑intensity measurements for Dn,f and Ln,f where applicable.
Revisions: This edition introduces the normalized flanking equipment sound pressure level and aligns with the ISO 10848 series frame document (ISO 10848‑1).

Applications

Product manufacturers: comparative performance testing and product data for marketing or technical dossiers.
Accredited test laboratories: standardized laboratory methods for reproducible flanking transmission data.
Acoustic consultants and building designers: input data for building‑acoustic prediction models (ISO 12354 series) and specification of building elements to meet sound insulation targets.
Specifiers and regulators: establishing performance requirements and demonstrating compliance for building elements such as suspended ceilings and access floors.
