ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one or several building components. ISO 10848-4:2017 specifies laboratory and field measurements of buildings where at least one of the elements that form the construction under test is a Type A element (defined in ISO 10848‑1). Laboratory measurements are used to quantify the performance of the junction with suppressed flanking transmission from the laboratory structure. Field measurements are used to characterize the in situ performance and it is not usually possible to suppress unwanted flanking transmission sufficiently; hence, the results are primarily representative of the performance of that junction when installed in that particular building structure. 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.

L'ISO 10848 (toutes les parties) spécifie les méthodes de mesure pour la caractérisation des transmissions latérales d'un ou de plusieurs éléments de construction. Le présent document spécifie les mesurages en laboratoire et les mesurages sur site des bâtiments dont au moins un des éléments qui constituent la construction soumise à l'essai est un élément de type A (défini dans l'ISO 10848‑1). Les mesurages en laboratoire sont utilisés pour quantifier la performance de la jonction avec suppression des transmissions latérales de la structure du laboratoire. Les mesurages sur site sont utilisés pour caractériser la performance in situ et il n'est généralement pas possible de supprimer suffisamment les transmissions latérales parasites; les résultats sont donc principalement représentatifs de la performance de cette jonction si elle est installée dans cette structure de bâtiment particulière. Les grandeurs mesurées peuvent être utilisées pour comparer différents produits, pour exprimer une exigence ou comme données d'entrée des méthodes de prévision telles que l'ISO 12354‑1 et l'ISO 12354‑2.

Overview
ISO 10848-4:2017 - part of the ISO 10848 series on building acoustics - specifies laboratory and field measurement methods for characterizing flanking transmission of airborne, impact and building-service-equipment sound across junctions where at least one element is a Type A element (see ISO 10848-1). The standard defines how to measure the vibration reduction index (Kij) for junctions, how to report results, and how to interpret laboratory (suppressed flanking) versus field (in‑situ) measurements. Measured data are suitable for product comparison, specification limits, or as input to prediction methods such as ISO 12354-1 and ISO 12354-2.
Key topics and requirements
- Measured quantity: Vibration reduction index, Kij, reported by frequency (one‑third octave bands) and as single‑number ratings per ISO 10848-1.
- Scope: Applies when at least one junction element is a Type A element (influenced by boundary conditions and modal behavior).
- Laboratory vs field:
- Laboratory tests aim to suppress unwanted flanking paths to quantify the junction itself.
- Field tests characterize in‑situ performance; unwanted flanking is often unavoidable and results are representative of that specific building installation.
- Instrumentation & test arrangement: Equipment and general facility requirements follow ISO 10848‑1. Installation details differ for Type A and Type B elements.
- Modal considerations: For Type A elements the mode count and modal overlap factor (M) are critical for measurement accuracy. M should be ≥ 1 at 250 Hz and above where possible; results where M < 0.25 must be flagged and treated with caution. Achieving 5+ modes per one‑third octave band is often recommended.
- Results and reporting: Kij values to one decimal place, plotted vs frequency on a logarithmic scale. Guidance is given for converting one‑third octave results to octave bands and for reporting structural reverberation times and test conditions.
- Precision & verification: Repeatability and uncertainty assessment per ISO 12999‑1; inter‑laboratory comparisons recommended.
Applications and users
- Compare junction designs and products (acoustic connectors, wall/floor junctions)
- Set contractual or regulatory requirements for flanking paths
- Provide input data for prediction models (ISO 12354 series) used in performance‑based design
- Typical users: acoustical consultants, test laboratories, product manufacturers, façade and building designers, and certification bodies
Related standards
- ISO 10848-1:2017 (frame document)
- ISO 12354-1 and ISO 12354-2 (prediction methods)
- ISO 12999-1 (measurement uncertainties)
- ISO 10140 series (report formats and plotting guidance)
This standard is essential for accurate assessment of flanking transmission where Type A elements (plate-like or modal-sensitive components) influence junction performance and overall sound insulation in buildings.

1 Scope
ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one
or several building components.
This document specifies laboratory and field measurements of buildings where at least one of the
elements that form the construction under test is a Type A element (defined in ISO 10848-1).
Laboratory measurements are used to quantify the performance of the junction with suppressed
flanking transmission from the laboratory structure. Field measurements are used to characterize
the in situ performance and it is not usually possible to suppress unwanted flanking transmission
sufficiently; hence, the results are primarily representative of the performance of that junction when
installed in that particular building structure.
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.

1 Domaine d'application
L’ISO 10848 (toutes les parties) spécifie les méthodes de mesure pour la caractérisation des
transmissions latérales d’un ou de plusieurs éléments de construction.
Le présent document spécifie les mesurages en laboratoire et les mesurages sur site des bâtiments dont
au moins un des éléments qui constituent la construction soumise à l’essai est un élément de type A
(défini dans l’ISO 10848-1).
Les mesurages en laboratoire sont utilisés pour quantifier la performance de la jonction avec suppression
des transmissions latérales de la structure du laboratoire. Les mesurages sur site sont utilisés pour
caractériser la performance in situ et il n’est généralement pas possible de supprimer suffisamment
les transmissions latérales parasites; les résultats sont donc principalement représentatifs de la
performance de cette jonction si elle est installée dans cette structure de bâtiment particulière.
Les grandeurs mesurées peuvent être utilisées pour comparer différents produits, pour exprimer

ISO 10848-4:2017은 건물 구성요소의 부발음 및 건물 서비스 장비 소음에 대한 이음 전달을 측정하기 위한 측정 방법을 규정하는 표준이다. 이 부분에서는 테스트되는 요소 중 적어도 하나가 A형 요소(ISO 10848-1에서 정의됨)인 건물에 대한 실험실 및 현장 측정을 규정하고 있다. 실험실 측정은 실험실 구조에서 불필요한 이음 전달을 억제한 상태에서 이음 공유의 성능을 정량화하는 데 사용된다. 현장 측정은 현장에서의 성능을 특성화하는 데 사용되는데, 불필요한 이음 전달을 충분히 억제하는 것이 일반적으로 불가능하기 때문에 결과는 특정 건물 구조에 설치된 해당 접합 부위의 성능을 주로 나타낸다. 측정된 양은 다른 제품을 비교하거나 요구 사항을 표현하거나 ISO 12354‑1 및 ISO 12354‑2와 같은 예측 방법에 대한 입력 데이터로 사용될 수 있다.

ISO 10848-4:2017 is a standard that specifies measurement methods for assessing the flanking transmission of building components. This particular part of the standard focuses on buildings where at least one of the elements being tested is a Type A element. The standard outlines both laboratory and field measurements. Laboratory measurements are used to evaluate the performance of the junction with suppressed flanking transmission, while field measurements provide information on the in situ performance, which may not always be able to eliminate unwanted flanking transmission. The results can be used to compare different products, establish requirements, or serve as input data for prediction methods such as ISO 12354‑1 and ISO 12354‑2.
ISO 10848-4:2017は、建築構造の一つ以上の要素のうち、少なくとも1つがタイプA要素である建物における、エアボーン、衝撃、および建物サービス機器の音響的な隣接部屋間の伝達を測定するための方法を規定する国際規格です。本規格では、実験室および現地での測定方法を特定しています。実験室での測定は、実験室構造からの不要な音響伝達を抑制した状態で、ジャンクションの性能を定量化するために使用されます。現地での測定は実態での性能を特性付けるために使用されますが、不要な音響伝達を十分に抑制することは通常不可能であるため、結果は特定の建物構造に設置されたジャンクションの性能を主に表しています。測定された量は、異なる製品を比較したり、要件を表現したり、ISO 12354‑1およびISO 12354‑2などの予測手法に入力データとして使用することができます。
ISO 10848-4:2017 is a standard that specifies measurement methods to determine the flanking transmission of building components. The standard focuses on buildings where at least one element of the construction being tested is a Type A element. It outlines both laboratory and field measurements. Laboratory measurements are used to assess the junction's performance with minimized flanking transmission, while field measurements reflect real-world conditions where suppressing unwanted flanking transmission may not be possible. The measured quantities can be used for product comparison, setting requirements, or as input data for prediction methods like ISO 12354‑1 and ISO 12354‑2.
