Key result

Type:

relative density

Density:

0.978 g/cm³

Temp.:

20 °C

Details on measurements and calculations:

Measurements performed:

m_1-Test 1 = 24.0976 g

m_1-Test 2 = 24.0874 g

m_1-Test 3 = 24.0729 g

m_2-Water = 24.5960 g

Density of the sample at 20°C:

Test 1: 0.978 g/cm^3

Test 2: 0.978 g/cm^3

Test 3: 0.977 g/cm^3

average value: 0.978 g/cm^3

Density of water at 4°C: 0.9999 g/cm^3

Relative density of the sample:

ρ rel = ρ sample (g/cm^3)/ ρ water (g/cm^3) = 0.978/ 0.9999 = 0.978

Conclusions:

Relative density (ISO 758-1976): 0.978

Executive summary:

The relative density was determined according to ISO 758-1976 (referenced to for pycnometric method for liquids within OECD 109) and OECD 109. Three replicate measurements were performed, resulting in a mean density of 0.978 g/cm^3 (Test 1: 0.978 g/cm^3; Test 2: 0.978 g/cm^3; Test 3: 0.977 g/cm^3). This equals the relative density D⁴₂₀ (dimensionless) of 0.978.
