- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- GLP compliance:

- Temp.:
- 20 °C
- Vapour pressure:
- < 0 Pa
- Conclusions:
- According to OECD 104 and EU Method A.4, the vapor pressure of Everzol Red CDN Crude at 20°C (293K) was < 1.33 × 10-8 Pa (< 1.00 × 10-10 mm Hg).
- Executive summary:
This test using the procedures outlined in the NOTOX Study Plan for 487467, OECD 104 and EU Method A.4. With the determination of the melting and boiling temperature of the test substance it was found that the compound reacted and/or decomposed at a temperature > 250°C. According to this, the temperature program was selected. The results of the test were compared with the results of benzo(ghi)perylene obtained with a similar temperature program during the validation test. The weight loss of the test substance at 210°C, 220°C, 230°Cand 240°C was lower than the weight loss of benzo(ghi)perylene at the same temperatures. Therefore, the vapor pressure of Everzol Red CDN Crude at 20°C (293K) was < 1.33 × 10-8Pa (< 1.00 × 10-10mm Hg).
Reference
The weight loss of the test substance at 210°C, 220°C, 230°Cand 240°C was lower than the weight loss of benzo(ghi)perylene at the same temperatures.

Additional information
With the determination of the melting and boiling temperature ofthe test substance it was found that the compound reacted and/or decomposed at a temperature > 250°C. According to this, the temperature program was selected. The results of the test were compared with the results of benzo(ghi)perylene obtained with a similar temperature program during the validation test. The weight loss of the test substance at 210°C, 220°C, 230°C and 240°C was lower than the weight loss of benzo(ghi)perylene at the same temperatures. Therefore, the vapor pressure of Everzol Red CDN Crude at 20°C (293K) was < 1.33 × 10-8 Pa (< 1.00 × 10-10mm Hg).
