5.2.1 General

a) Canisters from the same batch shall be used to evaluate all properties, as detailed in 5.3 to 5.8.

b) The application of PU adhesive foams for testing shall be performed using the adapter or the gun as

specified by the test sponsor.

c) The test canister(s) shall be conditioned at (23 ± 2) °C, (50 ± 5) % r.h. for at least 24 h prior to the

test.

d) Each canister shall be shaken vigorously at least 20 times just before application and the first

(50 ± 5) g of PU adhesive foam shall be discarded.

e) The test specimen shall be prepared and conditioned at (23 ± 2) °C, (50 ± 5) % r.h.

5.3.2 Test procedure (see Figures 1 to 3)

a) Five cylindrically shaped strings of PU adhesive foam, each with a diameter between 20 mm to

30 mm and a length of approximately 200 mm are dispensed onto the application substrate at a

rate of 50 mm/s to 100 mm/s. The nozzle should be at a distance of (10 ± 5) mm above the

substrate to avoid touching the dispensed foam.

b) After a minimum curing time of 24 h, the strings are trimmed at both ends to an overall length of

between 100 mm to 150 mm to form the test specimens.

c) The mass of each test specimen m shall be measured in grams with an accuracy of 0,1 g.

d) The measuring cylinder shall be filled to approximately 50 % of its capacity with tap water and the

reference volume V shall be recorded.

e) Each test specimen shall be submerged below the water surface in the measuring cylinder using the

blade of the cutting knife. The increased volume V shall be recorded immediately.

Figure 3 — Measurement
5.3.3 Calculation of results

The density of each of the five test specimens shall be determined using the following formula:

ρ × 1000 (1)
VV−
where
ρ is the foam density in kg/m3;
m is the mass of the specimen in g;
V is the volume level of water before the specimen immersion in ml;
V is the volume level of water and specimen following immersion in ml.
3 3

Each measurement is expressed in kg/m to an accuracy of 0,1 kg/m . The test result is the mean value

of five measurements.

If any measurement deviates more than ± 5 kg/m from the mean value, the test result shall be

discarded.

5.4.1.4 Stopwatch or clock capable of measuring in seconds.
5.4.2 Test procedure

a) One cylindrically shaped string of PU adhesive foam with a diameter of 20 mm to 30 mm is

dispensed onto the application substrate at a rate of 50 mm/s to 100 mm/s. The nozzle should be a

distance of (10 ± 5) mm above the substrate to avoid touching the dispensed foam. Record the time

at which dispensing started (t ).

b) The surface of the string shall be touched gently with the side of the small PolyEthylene rod/tube

without penetrating the skin (see Figure 4).
