Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 25 June 2010
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- according to guideline
- Guideline:
- other: Not stated
- Principles of method if other than guideline:
- Method used in the study: LCQC 001.
- Before measurement ensure that the instrument is set at the required temperature and that the relative constants have been set correctly.
- Check that the instrument has been cleaned properly, i.e that the air density reading is less than 0.0015.
- Place the sample in a small beaker and place the end of the sampling tube into the sample. Suck up sample into the instrument using a 2 mL syringe.
- Switch on the instrument light and check that there are no bubbles in the sample tube. Repeat the sampling as necessary.
- Switch off the light and allow the sample temperature to equilibrate. This is indicated by the period when the 'cooling' and 'heating' indicator lights are lit for approximately the same time.
- Check that the reading does not vary by more than 1 unit in either direction in 15 seconds.
- Read off the density of the sample. - GLP compliance:
- not specified
- Type of method:
- oscillating densitimeter
- Key result

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
