ASTM C1806-21

Standard Test Method for Measuring the Flow Rate of Aerosol Foam Sealants

SIGNIFICANCE AND USE
5.1 This test method provides a calculated data point regarding the amount of foam dispensed at one time from a single can of foam at standard laboratory conditions or a specific temperature and relative humidity range.  
5.2 Flow Rate does not predict the performance capability of the foam sealant or its suitability for the intended application.  
5.3 Flow Rate can be measured with a testing machine (Procedure B) or with the intended applicator or dispensing unit (Procedure A).  
5.4 The test is suitable for product performance certification and quality control programs, and can be useful to the general public, aerosol foam sealant manufacturers, distributors, specifiers, architects, contractors, testing laboratories, and other businesses and professionals.
SCOPE
1.1 This test method describes a procedure for determining the flow rate of aerosol foam sealants.  
1.2 Flow rate is determined in a controlled laboratory environment with manual dispensing (Method A) or using a flow rate machine (Method B).  
1.3 Currently, two foam sealant types are applicable to this test method: single component polyurethane and latex.  
1.4 There are no other known test methods specific for measuring the flow rate of aerosol foam sealants.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
