6. Glossary
Densité Optique (DO); optical density
For a given length, it is the decimal logarithm of the inverse of the transmission factor :
DO = log(1/T)
where T is the ratio of transmitted energy flux to incident flux.
if T = 0.1 = 10 –1 then DO = 1
Exposure Limit Value (ELV); Valeur Limite d'Exposition (VLE)
Maximum eye or skin exposure value at which no deleterious biological effects are expected, irreversible. (synonyms: LE and VLEP).
