Overview
EN ISO 10140-1:2021 - Acoustics - Laboratory measurement of sound insulation of building elements - Part 1: Application rules for specific products (ISO 10140-1:2021) defines how to apply the ISO 10140 laboratory measurement framework to particular building elements and products. This third-edition, CEN-endorsed standard (May 2021) updates the 2016 version and clarifies product-specific requirements for sound insulation, including preparation, mounting, test conditions, measured quantities and reporting.
Key technical topics and requirements
- Scope and purpose: Specifies application rules for laboratory measurement of sound insulation of building elements and products; complements the general procedures in ISO 10140-2 (airborne) and ISO 10140-3 (impact).
- Preparation and mounting: Detailed requirements for how test specimens (walls, floors, windows, doors, etc.) are prepared, mounted and supported in the test opening to ensure reproducible laboratory results.
- Operating and test conditions: Environmental and laboratory conditions, conditioning of specimens, and other operating constraints required for valid measurements.
- Applicable quantities: Defines which acoustic quantities to measure and report (e.g., sound reduction indices and related metrics) and references measurement procedures in ISO 10140-4 and ISO 10140-5.
- Reporting requirements: Additional product-specific information to be included in test reports so results are comparable and traceable.
- Product-specific annexes: Normative annexes cover common building elements, e.g.:
- Walls - airborne sound insulation
- Doors, windows, glazing, shutters - airborne sound insulation
- Floors - airborne and impact sound insulation
- Floor coverings and acoustical linings - improvement effects
- Small technical elements, joints, roofs/rooflights - special rules
- Normative references: Includes ISO 10140 series parts, ISO 717-1 (rating of sound insulation), and related ISO documents.
Practical applications and who uses this standard
- Laboratory test facilities use the standard to set up and conduct repeatable, compliant sound insulation tests for building elements.
- Manufacturers and product developers rely on it to evaluate and publish laboratory performance of walls, windows, doors, glazing, floors and acoustic treatments.
- Acoustic consultants and specifiers reference results generated under this standard when designing buildings or specifying products to meet acoustic performance targets.
- Certification bodies and regulators use the documented procedures to assess compliance and harmonize product declarations.
- Researchers benefit from consistent, comparable laboratory measurement methods for product development and validation.
