42、 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
43、 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 V0shall be recorded. e) Each test specimen shall be submerged below t
44、he water surface in the measuring cylinder using the blade of the cutting knife. The increased volume V1shall be recorded immediately.

46、ml; V1is the volume level of water and specimen following immersion in ml. Each measurement is expressed in kg/m3to an accuracy of 0,1 kg/m3. The test result is the mean value of five measurements. If any measurement deviates more than 5 kg/m3from the mean value, the test result shall be discarded.
