Nor1517A

Nor1517A Airflow resistance measurement system

The Nor1517A airflow resistance measurement system measures the airflow resistance in porous materials according to ISO 9053-2:2020.

Features

Measure the specific airflow resistance in Pa s m-1 according to ISO 9053-2 (2020): Acoustics – Determination of airflow resistance – Part 2: Alternating airflow method. Related quantities as airflow resistance and airflow resistivity may also be measured.

  • Measurement range: 10 Pa s m-1 to 30 000 Pa s m-1, up to 100 000 Pa s m-1 when correcting for non-linearities.
  • Airflow speed: 1,6 mm/s and 5 mm/s (r.m.s.) selected by the stroke 4,46 mm (Cal) or 14 mm (Meas)
  • Diameter of test area: 100 mm
  • Overall dimension (W×D×H): 590 mm × 290 mm × 640 mm
  • Power supply: 230 V/50 Hz (or 110 V/60 Hz – option US)
  • Weight: 19 kg

Options

  • Norsonic may deliver mounting devices for test materials.
  • Sample holder Nor1517A/02.

Standards

  • ISO 9053-2:2020
