- Conclusions:
- The relative density of the test item was determied at 20 °C by using the pycnometer method according to OECD Guideline 109.
The relative density of the test item was determined to 1.088 +- 0.008. - Executive summary:
The relative density of the test item was determined to 1.088 +- 0.008.
Reference
The relative density of the test item was determied at 20 °C by using the pycnometer method according to OECD Guideline 109. The empty and dry pycnometer is weighed. Then the test item is weighed into the pycnometer and covered with immersion liquid (Shellsol T). Remaining air is removed by evacuation, then the pycnometer is filled with immersion liquid and incubated at 20 °C. Afterwards the pycnometer is topped up to the mark, wiped and weighed.
The difference of total weight and the weight of the pycnometer with test substance is the weight of the immersion liquid.
The density of the immersion liquid is determined at 20 °C. First, the pycnometer is filled with water incubated at 20 °C and weighed. The procedure is repeated for the immersion liquid. The density of the test item is calculated according to following equation:
rho(test item) =
(m(test item) x (rho(immersion liquid)^-0.0012) / m1(immersion liquid) - m3(immersion liquid in addition to the sample)) + 0.0012
Relative density is calculated accoridng to equation shown below:
D420 = rho(test item, 20 °C) / rho(water, 4 °C)
The relative density of the test item was determined to 1.088 +- 0.008.
Description of key information
The relative density of the test item was determined to 1.088 +- 0.008.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.088
