The paper analyses the effective durabilty of a class A foam (Phos-Check WD 881) in different conditions of use. A test has been carried out in the prealpine area of the Belluno Province in the North-eastern part of Italy. The foam has been distributed in two different periods (autumn and summer), at three different concentrations (0.3% 0.6% 0.9%) and on four different surfaces (bared soil, meadow, broad-leaved floor and coniferous floor). The effective durability of the foam ranges from 20 minutes to 140 minutes. The concentration 0.9% offers the best results in both the two periods of the year and on the four substrates but it must be considered that during the summer it is more convenient to use the concentration 0.3% because it allows to obtain almost the same results of the concentration 0.9% saving the 75% of the concentrate.

Abstract
The paper analyses the effective durabilty of a class A foam (Phos-Check WD 881) in different conditions of use. A test has been carried out in the prealpine area of the Belluno Province in the North-eastern part of Italy. The foam has been distributed in two different periods (autumn and summer), at three different concentrations (0.3% 0.6% 0.9%) and on four different surfaces (bared soil, meadow, broad-leaved floor and coniferous floor). The effective durability of the foam ranges from 20 minutes to 140 minutes. The concentration 0.9% offers the best results in both the two periods of the year and on the four substrates but it must be considered that during the summer it is more convenient to use the concentration 0.3% because it allows to obtain almost the same results of the concentration 0.9% saving the 75% of the concentrate.Pubblicazioni consigliate
