It ferskil tusken eksploazjebestindich nivo AT6 en BT4

De eksploazjebestindige wurdearring foar Zone A is leger as dy foar Zone B; lykwols, de temperatuerklasse T6 is boppe T4. Dêrtroch, it is net passend om te beweare dat de iene in heger eksploazjebestindich nivo hat as de oare.

It is krekter om te sizzen dat elk is ôfstimd om te passen by ûnderskate flammable en eksplosive omjouwings.
