Full title and description

ISO 10140-1:2021 — Acoustics — Laboratory measurement of sound insulation of building elements — Part 1: Application rules for specific products. This part specifies application and reporting rules for laboratory measurements of sound insulation of building elements and products, including preparation and mounting of test specimens, required operating and test conditions, applicable acoustic quantities and additional information to be included in test reports.

Abstract

Part 1 of ISO 10140 defines the specific application rules used when performing laboratory measurements of airborne and impact sound insulation for a wide range of building elements and small technical products. It complements the measurement procedures given in the companion parts of the ISO 10140 series and sets out the information that must be recorded and reported to ensure comparability and reproducibility of laboratory results.

Scope

ISO 10140-1:2021 provides the application rules for performing laboratory measurements of sound insulation for building elements and products. It covers test specimen preparation and mounting, defined operating and environmental conditions, the acoustic quantities to be measured (for example sound reduction indices and normalized impact sound levels), and mandatory reporting items. The part is intended to be used together with the general measurement methods described in ISO 10140-2 (airborne) and ISO 10140-3 (impact) and with procedural and facility requirements in ISO 10140-4 and ISO 10140-5. The document includes annexes with product-specific application rules for elements such as walls, floors, doors, windows, glazing, floor coverings and small technical elements.

Key topics and requirements

• Detailed preparation and mounting requirements for test specimens to ensure reproducible boundary and mounting conditions.
• Specified operating and environmental conditions (room temperature, background noise limits, reverberation control) required during tests.
• Definitions of applicable acoustic quantities and measurement metrics (e.g., sound reduction index R, standardized level differences, normalized impact sound level L'n,w and frequency-dependent spectra).
• Requirements for instrumentation, calibration and measurement bandwidth (1/3-octave and octave band considerations where applicable).
• Mandatory report contents and presentation of results to ensure comparability (test arrangement sketches, specimen description, mounting details, measurement uncertainties and corrections).
• Annexed application rules for specific products (doors, windows, façades, floor systems, linings, small technical elements) that modify or add to general procedures.

Typical use and users

Laboratories performing laboratory sound insulation testing, product manufacturers (doors, windows, floor systems, glazing), acoustic consultants, test houses, certification bodies and regulatory authorities use ISO 10140-1 to ensure that laboratory measurements are carried out and reported consistently. It is also used by researchers and designers evaluating the acoustic performance of building elements and systems prior to in-situ installation.

Related standards

ISO 10140-1 is part of the ISO 10140 series. Closely related parts include ISO 10140-2 (measurement of airborne sound insulation), ISO 10140-3 (measurement of impact sound insulation), ISO 10140-4 (measurement procedures and requirements) and ISO 10140-5 (requirements for test facilities and equipment). ISO 10140 results are commonly used together with ISO 717-1 and ISO 717-2 (rating/assessment of airborne and impact sound insulation) for classification and regulatory purposes.
