STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: At room temperature protected from light - Key result
- Test no.:
- #1
- Temp.:
- 20 °C
- Vapour pressure:
- <= 0 Pa
- Key result
- Test no.:
- #2
- Temp.:
- 25 °C
- Vapour pressure:
- <= 0 Pa
- Conclusions:
- The vapour pressure of the substance was determined to be less than or equal to 0.000019 Pa at 20 °C and less than or equal to 0.000043 Pa at 25 °C.
- Executive summary:
The vapour pressure of the substance has been determined by an isothermal TGA effusion method according to OECD 104, EC A.4., and OPPTS 830.7950. At 20 °C the vapour pressure has been determined to be ≤1.9 × 10-5 Pa, and at 25 °C the vapour pressure has been determined to be ≤4.3 × 10-5 Pa.
