Density

Link to relevant study record(s)

Reference

Endpoint:

relative density

Type of information:

experimental study

Adequacy of study:

key study

Study period:

6-10 August 2010

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study without detailed documentation

Remarks:

The study was conducted according to an internationally recognised method, and under GLP. The substance is adequately identified, but details on composition are missing. Therefore validation applies with restrictions.

Qualifier:

according to guideline

Guideline:

EU Method A.3 (Relative Density)

Deviations:

no

Principles of method if other than guideline:

Not applicable

GLP compliance:

yes (incl. QA statement)

Remarks:

effective 24 July 2009 (validity 18 months)

Type of method:

pycnometer method

Specific details on test material used for the study:

Storage conditions of test material: Stored at room temperature protected from direct sun light.

Table 4.4/1: Density results

 

Replicate	Certified volume	Empty weight	Test with water		Test with test item		Relative density D20/4
			Temperature	Total weight	Temperature	Total weight
1	50.007	35.6274 g	4.4 °C	85.5621 g	20.3 °C	78.0114 g	0.849
2	51.841	31.4314 g	4.4 °C	83.1954 g	20.3 °C	75.3741 g	0.849

 

Relative density D20/4 = 0.849 ± 0.000

Density = 0.848 g/mL

Conclusions:

The substance is much less dense than water.

Executive summary:

The density of the test substance was measured under GLP according EU A3 guideline, pycnometer method.

 

Experiment was performed at 20 °C in duplicate, and compared to water at 4.4°C.

 

The relative density (D20/4) of the test substance was calculated to be 0.849.

Description of key information

The substance is much less dense than water.

Key value for chemical safety assessment

Relative density at 20C:

0.849

Additional information

A reliable experimental study, conducted according to a recognized EC method and under GLP, is available.

Despite minor restrictions due to incomplete test item identification, it is considered as a key study, and the result is retained as key data.
