Characterisation of one component foam - Part 1: Foam yield characteristics
This document specifies test methods for the evaluation of the foam yield characteristics 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 - Determination of the apparent density of an OCF extruded in a joint and calculation of the theoretical foam yield in running meters of the whole can.
- Method 2 - Determination of the real yield of cured foam, respecting eventual cavities inside the foam structure.
- Method 3 - Determination of the free foamed density of a cured OCF for identification purposes only.
- Method 4 - Determination of the total foam yield for the whole OCF container for moisture and self-curing foam that can be measured by water displacement.

4 Test methods
4.1 Method 1 – Joint foamed density and foam yield
4.1.1 Principle
The foam is dispensed into a joint with fixed dimensions. The joint foamed density of the cured foam is
calculated using the weight and volume of the foam. The theoretical joint foam yield is calculated by
measuring the amount sprayed.
NOTE Joint density can differ from the free foamed density determined by Method 3 in 4.3.
4.1.2 Equipment
For each joint:
4.1.2.1 2 gypsum boards, with dimensions 420 mm × 100 mm × 12,5 mm.
4.1.2.2 2 spacers, not water absorbing, not adherent (e.g. polyethylene (PE),
polytetrafluoroethylene (PTFE), on which polyurethane (PU) does not adhere), dimensions:
100 mm × 30 mm × 30 mm.
4.1.2.3 Joint mould of inner dimensions 360 mm × 100 mm × 30 mm.
4.1.2.4 Uncoated paper, recommended A3 typewriter
Additional tools:
4.1.2.5 Weighing scale with an accuracy of ±0,1 g.
4.1.2.6 Sharp and clean knife blade.
4.1.2.7 Conditioning chamber capable of being controlled at (23 ± 2) °C and (50 ± 5) % RH.
4.1.3 Sampling
4.1.3.1 Conditioning
The test conditions shall be (23 ± 2) °C and (50 ± 5) % relative humidity unless indicated otherwise.
Bring the test container, gypsum board and paper to the test conditions for at least 24 h.
4.1.3.2 Test pieces
A minimum of three samples shall be subjected to the tests given in this section to obtain accurate
measurements of material properties.
