The static airflow resistance meter is designed to obtain reliable measurements of the static airflow resistance, resistivity, and static viscous permeability for a wide range of open cell porous materials used in noise control. The system is based on the direct method described in ASTM C522-03 and ISO 9053-91 standards.
➡ Static airflow resistivity (Pa.s/m² or rayls/m)
➡ Static airflow resistance (Pa.s/m or rayls)
➡ Static viscous permeability (m² or Darcy)
Mecanum’s static airflow resistance meter is used by the world’s leading material suppliers for both automotive and aircraft industry for quality control in the manufacturing process of materials; research, development, and innovation, and for feeding acoustical prediction software dealing with sound absorbing materials.
The system includes:
- Two specimen holders (100-mm and 44.44-mm diameter) *(other sizes are available)
- Thin film holder
- Certified calibrated resistance
- Grids to support limp material
- Rings to minimize airflow leaks around the sample
- SIGMA-X software
The SIGMA-X software fully controls the measurement and calculates the main properties and statistics related to the measurement. It corrects pressure and temperature. The system works with disc shaped samples.
Optional calibrated samples, holders and air compressor unit are available.
Mecanum can manufacture custom systems to meet your exact application requirements such as specific sample holder or specific measurement range.
