Study design

Test type:
static
Water media type:
freshwater
Limit test:
yes
Total exposure duration:
48 h

Test conditions

Test temperature:
18-22°C, constant within ±1°C.
pH:
Between 6 and 9. Should normally not vary by more than 1.5
unit.
Dissolved oxygen:
No aeration of the test solutions.
Nominal and measured concentrations:
Samples for possible analysis will be taken from all
concentrations and the control immediately before transfer to
the individual replicates. Care will be taken not to include any
floating layer, test item film or undissolved material in separate
vessels. At the end of the test samples will be taken from the
approximate center of the pooled solutions (provided that
solutions are still homogeneous) of the vessels at each
concentration. In case of volatile items solutions will not be
pooled before sampling. Instead, samples will be taken from at
least one replicate.
