Applicant's summary and conclusion

Conclusions:
The relative density of the test item has been determined to be 1.21 at 22.2 ± 0.5°C
Executive summary:

The relative density for the substance SLI(76) stripped conducted in study number 2517/0001 was carried out using a gas comparison pycnometer, Method A3 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC). The relative density of the test item has been determined to be 1.21 at 22.2 ± 0.5°C.
