This document specifies test methods for the evaluation of the
mechanical 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 – Compression strength: This test method describes
how to determine the compressive strength of a cured foam. It
gives an indication of the foams resistance against area
distributed pressure. The maximum endurable stress is
determined.
-
Method 2 – Movement capability: This test method describes
how to determine the movement capability of cured foam. The
result gives an indication of the degree of flexibility of the
cured foam.
-
Method 3 – Bonding strength: The method displays the
measurement of the bonding power of a One Component (Foam)
Adhesive, dispensed from a pressurized foam container, between
two substrates with direct contact.
-
Method 4 – Tensile strength: This test method describes how
to determine the maximum stress a cured foam can withstand
while being stretched before breaking. The result gives an
indication of the elasticity of the cured foam.
-
Method 5 – Shear strength: This method displays the
behaviour of a foam system towards shear forces. It shows the
strength and the bonding power of the foam as the sandwich
element between wooden plates. The test is conducted according
to
EN 12090 .
