Full title and description

ISO 10140-5:2021 — Acoustics — Laboratory measurement of sound insulation of building elements — Part 5: Requirements for test facilities and equipment. This part of the ISO 10140 series specifies the laboratory test facilities and the equipment needed to perform reproducible sound insulation measurements of building components, building elements and small technical elements, and it defines qualification and commissioning procedures for test facilities and equipment.

Abstract

Specifies requirements for laboratory test facilities where flanking transmission is suppressed and structural isolation exists between source and receiving rooms; covers facility characteristics, measurement equipment, commissioning and periodic qualification procedures to ensure valid airborne and impact sound insulation measurements of components, building elements and sound-insulation improvement systems.

• Publication date: April 2021 (ISO edition published 2021-04).
• Publisher: International Organization for Standardization (ISO); adopted national publishers and bodies produce regional publications (examples include BSI and DIN).
• ICS / categories: 91.120.20 (Acoustics in building. Sound insulation).
• Edition / version: Edition 2 (2021).

Scope

Applies to laboratory test facilities and equipment for measuring airborne and impact sound insulation of building elements, components and small technical elements under controlled conditions where flanking transmission is suppressed. It specifies the physical and acoustic characteristics of source and receiving rooms, instrumentation and tapping/impact sources, procedures for commissioning a new facility and periodic checks to verify continued conformity of the facility and equipment. The document is intended for laboratory (not in-situ) measurements used for product comparison, classification and R&D.

Key topics and requirements

• Definition of acceptable test-facility geometry and room volumes, and guidance on room surface treatments and boundary conditions to achieve reproducible results.
• Requirements for suppression of flanking transmission and structural isolation between source and receiving rooms.
• Instrumentation and calibration: sound sources, reference microphones, measurement systems and traceability considerations.
• Background noise, signal-to-noise ratio, reverberation time measurements and acceptable limits for valid tests.
• Impact-source specifications (standard tapping machine and alternative impact sources) and references to tapping-machine details used in ISO 10140-3.
• Commissioning and qualification procedures for new facilities, periodic verification tests, and recommended documentation and reporting elements.
• Consideration of measurement uncertainty and reproducibility to support product comparison and classification.

Typical use and users

Used by accredited acoustical test laboratories, product manufacturers (doors, windows, façades, partition systems, floor constructions), façade and building-product test centres, certification bodies, acoustical consultants and research institutes for laboratory measurement, product development, quality control and conformity assessment. National standards bodies and test houses also use this standard when adopting EN/ national versions.

FAQ

Q: What is this standard?

A: ISO 10140-5:2021 is the part of the ISO 10140 series that defines requirements for laboratory test facilities and the equipment needed to carry out reliable sound-insulation measurements of building elements.

Q: What does it cover?

A: It covers physical and acoustic characteristics of source and receiving rooms, instrumentation and calibration, acceptable background noise and reverberation limits, impact-source specifications, commissioning/qualification procedures for test facilities and periodic verification to maintain measurement validity.

Q: Who typically uses it?

A: Accredited test laboratories, product manufacturers, certification bodies, acoustical consultants and research institutes use it for laboratory testing, product development, quality control and conformity assessment. National adoption bodies (for example BSI, DIN, NEN) publish localized versions for regional use.

Q: Is it current or superseded?

A: Current — ISO 10140-5:2021 (Edition 2) replaces the earlier 2010 edition and its 2014 amendment. The 2021 edition is the active international edition.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 10140 series (Parts 1–4 and others) covering laboratory measurement of sound insulation; those parts define application rules, airborne and impact test methods and measurement procedures used alongside Part 5.

Q: What are the key keywords?

A: Acoustics; sound insulation; laboratory measurement; test facility; tapping machine; airborne sound; impact sound; measurement uncertainty; flanking transmission.
