Overview
EN ISO 9053-1:2026, published by CEN and based on ISO/FDIS 9053-1:2026, establishes a standardized static method for determining the airflow resistance of porous materials used in acoustical applications. The document specifically addresses measurement within a laminar flow regime, ensuring consistency and accuracy when evaluating materials intended for sound insulation, sound absorption, or other noise control functions.
Airflow resistance is a critical property influencing the acoustic effectiveness of materials such as foams, fibrous panels, and textiles. This standard supports materials testing in construction, automotive, and industrial acoustics, helping manufacturers, laboratories, and quality assurance teams to reliably assess products for optimal sound attenuation and insulation.
Key Topics
