This document specifies test methods for the evaluation of the
expansion properties for moisture curing, self-curing activatable
or water drying foams dispensed from single pressurized foam
containers.
This document 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 document to establish appropriate safety and
health practices and determine the applicability of regulatory
requirements prior to use.
The following test methods are described:
-
Method 1 – Dimensional stability: This test method describes
how to determine the dimensional stability (shrinkage or
expansion) of cured foam under typical and extreme
conditions.
-
Method 2 – Curing pressure: This method describes how to
determine the generation of pressure during the curing process
of an OCF.
-
Method 3 – Post expansion: This method describes how to
measure the expansion of a dispensed froth during the curing
phase.
