Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Reference
Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2010-01-27 till 2010-01-29
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.3 (Relative Density)
Deviations:
no
Principles of method if other than guideline:
The test fluid is continuously flowing through a swinging U pipe which is electromagnetically stimulated to oscillate at its resonance frequency. The cycle time is a function of mass and temperature and therefore – in a defined volume – density. The evaluation proceeds automatically in the measuring equipment.
GLP compliance:
yes (incl. QA statement)
Type of method:
oscillating densitimeter
Type:
relative density
Density:
1.01
Temp.:
20 °C

Result:

Relative density D20/4:

1. Measurement = 1.010,

2. Measurement = 1.010;

mean value = 1.010

Conclusions:
The relative density of ‘N-1,4-dimethylpentyl-N’-phenyl-p-phenylenediamine' is specified as D20/4 = 1.010 (Currenta, 2009).
Executive summary:

The relative density of ‘N-1,4-dimethylpentyl-N’-phenyl-p-phenylenediamine' is specified as D20/4 = 1.010.

Description of key information
