ASTM C1806-21 PDF Download

ASTM C1806-21 is a standard test method that outlines the procedure for measuring the flow rate of aerosol foam sealants. The flow rate is determined in a controlled laboratory environment using either manual dispensing or a flow rate machine. This test method provides a calculated data point that indicates the amount of foam dispensed from a single can of foam at standard laboratory conditions or specific temperature and relative humidity range.

It should be noted that the flow rate does not predict the performance capability of the foam sealant or its suitability for the intended application. However, this test can be useful for product performance certification and quality control programs. It is applicable to both single component polyurethane and latex foam sealants.
