F0023 - Digital Foam Porosity Tester

The Digital Foam Porosity Tester is an instrument for monitoring the porosity of flexible cellular polyurethane. The machine determines the ease with which air passes through a cellular structure. Airflow values may be used as an indirect measurement of certain cell structure characteristics.

A flexible cellular test piece, 50mm x 50mm x 25mm, is placed in a cavity over a vacuum chamber and a specified constant differential air pressure is created. The rate of airflow required to maintain this pressure, is the airflow value. 

The Foam Porosity Digital Tester meets the following standards:

• AS 2282.14
• ASTM D3574 - Test G
• ISO 7231
• BS EN ISO 7231
• DIN EN ISO 7231
• EN ISO 7231
