Описание (английский):

This document specifies procedures for assessing the measurement uncertainty of sound insulation in building acoustics. It provides for — a detailed uncertainty assessment; — a determination of uncertainties by inter-laboratory tests; — an application of uncertainties. Furthermore, typical uncertainties are given for quantities determined according to ISO 10140 (all parts), ISO 16283 (all parts) and ISO 717 (all parts).

Overview

EN ISO 12999-1:2020 - "Acoustics - Determination and application of measurement uncertainties in building acoustics - Part 1: Sound insulation" - specifies procedures to assess and apply measurement uncertainty for sound insulation in building acoustics. Published by CEN and identical to ISO 12999-1:2020, this second edition updates the earlier 2014 version and provides both procedural guidance and typical uncertainty values for common acoustic measurands.

Key topics

Scope and purpose

Procedures for: a detailed uncertainty assessment, determination of uncertainties by inter‑laboratory tests, and practical application of uncertainties.
Typical uncertainties for quantities measured according to ISO 10140, ISO 16283 and ratings in ISO 717.

Measurement concepts and definitions

Clear definitions for measurand, measurement result, uncertainty, standard uncertainty (u), combined standard uncertainty (uc), expanded uncertainty (U) and coverage factor (k).

Uncertainty methods

Detailed uncertainty budgets (Clause 4 and Annex C) following the principles of ISO/IEC Guide 98‑3 where applicable.
Use of repeatability and reproducibility concepts and inter‑laboratory comparisons to determine method uncertainty (Clause 5).
Treatment and reporting of single‑number values and their uncertainties (Clause 6–7).

Supporting material

Informative annexes with worked examples for handling uncertainties, example calculations for single-number values, and guidance on reproducibility limits for airborne sound insulation (Annexes A–D).

Practical applications

Accurate reporting of test results: Laboratories use the standard to calculate and report measurement uncertainty with airborne and impact sound insulation results.

Inter-laboratory validation: Standardizes procedures for round-robin tests to derive method uncertainty and identify outliers.

Product development and comparison: Manufacturers and acoustic consultants use uncertainty assessments when comparing materials, assemblies or product performance.

Regulatory compliance and contracts: Authorities, specifiers and clients rely on uncertainty-aware results for acceptance criteria, performance verification and building code compliance.

Quality assurance: Establishing uncertainty budgets supports laboratory accreditation and consistent test outcomes.

Who should use this standard

Acoustic testing laboratories and measurement technicians

Manufacturers of building elements (walls, floors, windows, façades)

Building acoustics consultants and façade designers

Certification bodies, regulators and product specifiers

Researchers working with ISO 10140 / ISO 16283 / ISO 717 test methods

Related standards

ISO 10140 (laboratory measurements of sound insulation)

ISO 16283 (field measurements of sound insulation)

ISO 717 (rating of sound insulation)

ISO/IEC Guide 98‑3 (GUM) and ISO 5725 (repeatability & reproducibility)

Using EN ISO 12999-1:2020 ensures measurement uncertainty is handled consistently across laboratories and applications, enabling reliable comparisons and defensible acoustic assessments.
