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
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.
