Test conditions:
1000 hours@80°C under pressure
Measures and calculation: ASTM D-471-72 method
W1 = initial weight of sample in air [gr]
W2 = initial weight of sample in water [gr]
W3 = weight of sample after immersion, in air [gr]
W4 = weight of sample after immersion, in water [gr]Volume change [%] = (W3 - W4) - (W1 - W2) X 100
W1 - W2
Weight change [%] = - (100 - 100 W3 )
W1Hardness [shore A] after immersion and 72 h drying.
