Significance and Use | ||||
5.1 Post dispensing volumetric expansion factor 5.2 Post dispensing volumetric expansion factor 5.3 This test method is intended to lend guidance in product selection as related to the post dispensing expansion characteristics of the aerosol foam sealants. 5.4 This test method recognizes that the results are reflective of controlled laboratory conditions. Post dispensing expansion in field applications may vary according to temperature, humidity, and surfaces that the aerosol foam sealants are in contact with. |

1. Scope | ||||
1.1 This test method measures the volumetric expansion of aerosol foam sealants after dispensing. 1.2 This test method provides a means for estimating the quantity of initial material required to dispense in order to fill a cavity. 1.3 Aerosol foam sealants are used for a variety of applications intended to reduce airflow through the building envelope. 1.4 This test method applies to two types of single component aerosol foam sealants: polyurethane and latex. 1.5 There are no other known standard test methods to measure aerosol foam sealants post dispensing expansion. 1.6 Values are reported in SI units only. Certain apparatus and supply items are referenced in inch-pound units for purchasing purposes. 1.7 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 and health practices and determine the applicability of regulatory limitations prior to use. |
