Explanation of symbols for metallic materials:
0 = practically resistant, loss in weight less than
2,4 g/m2/day
1 = fairly resistant, loss in weight 2,4–24 g/m2/day
2 = low resistance, loss in weight 24–72 g/m2/day
3 = non-resistant, loss in weight more than 72 g/m2/day
– = not tested or not customary
for sealing materials:
• = suitable
– = not suitable
Bp. = boiling point
satd. sol. = saturated solution
hyd.sol. = hydrous solution
conc. = concentrated
