A mixture of Fendolite MII and water was prepared by mixing 20 kg of Fendolite MII and 15-19 liters of water for 3 minutes. The mixture was then sprayed from a spray head to conduct a density test. The spray was collected in an empty 1 liter container, filled to the brim without mixing, and weighed. The weight of the mixture was 1671 grams and the empty container was 504 grams, resulting in a density measurement of the spray head mixture of 1167 grams, within the required range of 1000 to 1300 grams.

DENSITY TEST SPRAY HEAD (Y3DC)
So spray head density is
1671 – 504 = 1167 gms
which is within the required range of
1000 to 1300 gms
1671 gms is the weight of the
Fendolite MII & water mixture sample
504 gms is the weight of empty 1 litre
container
