6.2.4.3 Calculating the fogging value G
To calculate G in mg, the value of G j is calculated for each glass plate by using:
G
= G
– G
j
1
0
where
G
is fogging mass of condensation on each piece of aluminium foil
j
G
is the mass of the aluminium foil after the test, in mg
1
G
is the mass of the aluminium foil before the test, in mg
0
The fogging value G is the mean value of G
