Water content

Mean Karl Fischer factor = 4.78 mg/mL

Mean water content = <0.1 % w/w

Interpretation of results:

other: Not classified in accordance with EU criteria

Conclusions:

Under the conditions of the test, the test substance was determined not to have explosive properties.

Executive summary:

In a GLP compliant explosive properties study conducted in accordance with standardised guideline EU Method A.14, the explosive properties of the test material was determined using the BAM fall hammer test and Koenen steel tube test. Under the conditions of the test, the test material was determined not to have explosive properties.

Description of key information

Non-explosive; study conducted in accordance with EU Method A.14; Tremain (2000b)

Key value for chemical safety assessment

Explosiveness:

non explosive

Additional information

In a GLP compliant explosivity study conducted in accordance with a standardised guideline, the explosive properties of the test material were determined. Under the conditions of the test, the substance was determined to be non-explosive.

Justification for classification or non-classification

In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to explosiveness.
