Temp.:
20 °C
Remarks on result:
other: Mean density value at 20°C is 0.8619 g/cm3. The standard deviation is ± 0.0000 g/cm3.

Measured density of the test substance at 20°C:

- measurement 1: 0.8619 g/cm3

- measurement 2: 0.8619 g/cm3

- measurement 3: 0.8619 g/cm3

- measurement 4: 0.8619 g/cm3

Mean value at 20°C is 0.8619 g/cm3. The standard deviation is ± 0.0000 g/cm3.

Conclusions:
The relative density of the test substance was determined according to EC Regulation No 440/2008, Guideline A.3, and according to OECD Guideline 109. The relative density of tert-pentyl peroxypivalate, 75% solution in isododecane is 0.8619 (± 0.0000). Note that the organic peroxide cannot be handled in pure form.
Executive summary:

The relative density of tert-pentyl peroxypivalate, 75% in isododecane was determined according to EC Regulation No 440/2008, Guideline A.3 [1] and according to OECD Guideline 109 [2], and in accordance with European Chemicals Agency (ECHA), Guidance on information requirements and chemical safety assessment, Chapter R.7a, Endpoint specific guidance, May 2008 [3]. The relative density of tert-pentyl peroxypivalate, CAS 29240-17-3, 75% in isododecane at 20°C is 0.8619 (± 0.0000). Note that the organic peroxide cannot be handled in pure form.
