Results and discussion
Any other information on results incl. tables
In the test medium and the blank control vessels of the 24-h pre-test @ 100 rpm at pH 6 and pH 8 the concentration measurements for silver, cobalt, chromium, copper, nickel and lead were below the corresponding limits of detection.
pH 6
In the blank corrected test vessels of the 24-h pre-test @ 100rpm at pH 6 no amounts of dissolved chromium have been measured. Small amounts of silver (0.07 μg Ag/L), cobalt (0.16 μg Co/L) , copper (0.83 μg Cu/L), nickel (0.50 μg Ni/L) and lead (0.11 μg Pb/L) have been measured with coefficients of variation of 58% for silver, 31% for cobalt, 9% for copper, 16% for nickel and 37% for lead. The coefficients of variation of silver, cobalt and lead exceeded the quality criterion of 20%, probably due to low concentration values near the detection limits.
pH 8
In the blank corrected test vessels of the 24-h pre-test @ 100rpm pH 8 no amounts of dissolved chromium, copper and nickel have been measured. Low concentrations of silver (0.11 μg Ag/L), cobalt (1.25 μg Co/L) and lead (0.10 μg Pb/L) were measured with coefficients of variation of respectively 81%, 91% and 93%. The coefficients of variation of silver, cobalt and lead exceeded the quality criterion of 20%, probably due to low concentration values near the detection limits or to the fluctuation of the pH.
There was a large within- and between-vessel variation for cobalt.
Applicant's summary and conclusion
- Conclusions:
- The worst case pH defined in this test is pH 6. Silver, cobalt, copper, nickel and lead are the measured elements which showed dissolution above the limits of detection and may be important in the design of a full test for classification purposes. The pH didn’t stay between the proposed ranges (pH 6 or pH 8 ± 0.2) for all test vessels.
- Executive summary:
The worst case pH defined in this test is pH 6. Silver, cobalt, copper, nickel and lead are the measured elements which showed dissolution above the limits of detection and may be important in the design of a full test for classification purposes. The pH didn’t stay between the proposed ranges (pH 6 or pH 8 ± 0.2) for all test vessels.
This study is considered reliable an acceptable for use for this endpoint.
