Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

bulk density
Density:
600 g/L
Temp.:
25 °C
Conclusions:
The bulk density of the test item was determined to be 600 g/L.
Executive summary:

The purpose of the study was to determine the density of the test article at a specific temperature. Due to the chemical properties of the test item it was not possible to determine the density by means of a gas comparison pycnometer according to EEC- and OECD guidelines which would require the drying of the test item. Therefore, the bulk density was determined instead in order to provide data of practical relevance. The density of the dried material is not relevant because it will not be handled. The determination of the bulk density of the test article was performed in accordance with the EPA 712-C-96-035: OPPTS 830.7300 Melting Point/Melting Range (Product Properties Test Guidelines), August 1996 and CIPAC Handbook, Volume F, MT 159, Physico-chemical Methods for Technical and Formulated Pesticides, 1995. The test was performed at room temperature and in duplicate. The density of the test article GAP was determined to be 600 g/L using a simplified measurement cylinder test.
