Reference

Reference 1

Endpoint:

explosive properties of explosives

Type of information:

experimental study

Adequacy of study:

supporting study

Study period:

20 - 22 Jul 1999

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.14 (Explosive properties)

Deviations:

yes

Remarks:

The thermal sensitivity test was conducted with the modification to the tube packing procedure as detailed in "Safety characteristic data of explosive substances - Methods of the bundesanstalt für Materialprüfung - BAM", KOENEN, IDE and SWART.

GLP compliance:

yes

Parameter:

thermal sensitivity - Koenen test: diameter of the orifice plate

Remarks on result:

not thermal sensitive if heated under defined confinement

Parameter:

sensitiveness to impact: impact energy (J)

Remarks on result:

not sensitive to impact using an impact energy of 40 J

Parameter:

sensitiveness to friction: friction load (N)

Remarks on result:

not sensitive to friction using a friction load of 360 N

Koenen steel tube test:

Hole diameter / mm	Weight / g (volume = 27,14 cm³)	T1 / s	T2 /s	Results
6	27.886	21	193	No explosion
6	27.872	30	180	No explosion
6	27.887	27	190	No explosion
2	27.876	30	175	No explosion
2	27.819	25	168	No explosion
2	27.873	28	169	No explosion

T1: time from application of the flame to a noticeable effect from the orifice

T2: time from application of the flame to the end of combustion without recorded event (e. g. explosion) as in these tests or to an explosion

 

No signs of explosion in the tests with 6 mm plate hole diameter and in the tests with 2 mm hole plate in the Koenen test.

No signs of vigorous reaction in all 6 trials at 10 kg drop hammer weight and 0.4 m drop height in the fallhammer test.

No signs of vigorous reaction in all 6 trials at 360 N and 10 mm distance in the BAM friction apparatus.

Interpretation of results:

GHS criteria not met

Reference 2

Endpoint:

explosive properties of explosives

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties

Description of key information

non explosive

Key value for chemical safety assessment

Explosiveness:

non explosive

Additional information

There are no chemical groups available in the molecule that are associated with explosive properties. This statement was confirmed by the test determined according to EU Method A.14.

Justification for classification or non-classification

The available data on explosivity of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 and are therefore conclusive but not sufficient for classification: The substance is not explosive according to the criteria of UN RTDG Test Series 2.
