Study title: Relative density of Pencycuron (NTN 19701), technical substance
Test Guideline: 92/69/EEC, Part A, Method A.3., OECD 109 EPA Product Properties Test Guideline OPPTS 830.7300
The relative density of Pencycuron (NTN 19701), technical substance was determined according to the above mentioned guidelines.
The relative density of Pencycuron (technical substance) at 20°C was (compared to water at 4 °C):
D420 = 1.23

Mean Density g / cm3 | 1.2251 | 1.2418 | ||
Mean (experiments 1 to 2) 1.23 g/cm3
Standard deviation: 0.012 g/cm3
Relative standard deviation: 1.0 %
Relative density of Pencycuron (compared to water at 4 °C) was:
D420 = ρp20/ρw4= 1.23g/cm3/ 1.000g/cm3 = 1.23
Final Result
The relative density of Pencycuron (NTN 19701), technical substance was determined ac-cording to the above mentioned guidelines.
The relative density of Pencycuron (technical substance) at 20°C was (compared to water at 4 °C):
D420 = 1.23
Description of key information
The relative density of the test substance is 1.23 g/cm³.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.23
