Applicant's summary and conclusion

Conclusions:
The results obtained with GR-85-2517 at 20°C were:

First determination: density = 0.875 g/mL
Second determination: density = 0.876 g/mL
Average (rounded off): density = 0.876 g/mL
Estimated precision : +/- 0.001 g/mL
Executive summary:

The density of GR - 85 -2517 was determined according to the OECD guideline No. 109 (oscillating densimeter method). The result can be expressed as follows:

density = 0.876 +/- 0.001 g/mL at 20°C

or D204 = 0.876 +/- 0.001
