ELEMENTS OF THE DETERMINATION OF COMPLIANCE
Obtain Restriction Limit
for substance in question (RL)
if units are by area,
(e.g. mg/dm²)
if units are by weight,
(e.g. mg/g)
Convert limit to mg/kg using
formula given in Note 1, below
Convert limit to mg/kg
Compare Limit to Total Extract (TE)
to determine compliance as shown in Figure 1
Perform extraction test on paper sample for chemical
in question and quote result in mg/kg
(= “Total Extract” TE)
Note
Qa x 100000
Qm =
G
Qm = concentration of substance in paper as mg/kg
Qa = concentration of substance in paper as mg/dm²
G = grammage of paper as g/m²
