Division 2.1 Requirement for the lubricant and its main components
United Kingdom
The critical concentration for the aquatic toxicity for both the freshly prepared lubricant and for each main component shall not be lower than the values specified in Table 2.
Main component means any substance accounting for more than 5 % by weight of the lubricant.
Table 2
Aquatic toxicity values for both freshly prepared lubricant and for each main component
| ALL | PLL | TLL | ||
|---|---|---|---|---|
| Aquatic toxicity for the freshly prepared lubricant | Critical concentration for acute aquatic toxicity OR | > 100 mg/l | > 1 000 mg/l | > 1 000 mg/l |
| Chronic aquatic toxicity | > 10 mg/l | > 100 mg/l | > 100 mg/l | |
| Aquatic toxicity for each main component | Critical concentration for acute aquatic toxicity OR | > 100 mg/l | ||
| Chronic aquatic toxicity | > 10 mg/l | |||
Available acute aquatic toxicity test data for each main component shall be provided on each of the following two trophic levels:
-
crustacean (daphnia preferred),
-
aquatic plants (algae preferred).
In case acute aquatic toxicity test data is missing in one or both trophic levels, available test data on chronic aquatic toxicity for both the crustacean (daphnia preferred) and fish trophic level shall be accepted.
QSARs could be used to fill data gaps for chronic toxicity or for acute toxicity in only one of the relevant trophic levels.
In case the aforementioned test data is not available for each main component, a test shall be performed to generate data for acute toxicity in the missing trophic level/s (i.e. crustacean and/or aquatic plants).
Available acute aquatic toxicity test data for the lubricant shall be provided on each of the following three trophic levels:
-
crustacean (daphnia preferred),
-
aquatic plants (algae preferred),
-
fish.
In case acute aquatic toxicity test data for the applied lubricant is missing for any of the mentioned trophic levels available test data on chronic aquatic toxicity shall be accepted for the missing trophic level/s.
In case the above data is not available for the applied lubricant, a test shall be performed to generate data on acute aquatic toxicity for the missing trophic level/s.
