Reference
Endpoint:
explosive properties of explosives
Type of information:
experimental study
Adequacy of study:
key study
Study period:
The study was conducted between 8 May 1998 and 15 May 1998
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.14 (Explosive properties)
GLP compliance:
yes (incl. QA statement)
Specific details on test material used for the study:
Identification: BHES-100X
Description: off white solid block
Batch number: 1A0110
Date received: 20 January 1998
Storage conditions: room temperature in the dark
Test series:
UN Test series 3
Method:
UN Test 3 (a) (ii): BAM Fallhammer
Parameter:
other: Observations were made for any signs of an explosion
Result:
negative, no explosion
Remarks on result:
no ignition, explosion, self-heating or visible decomposition
Test series:
UN Test series 3
Method:
UN Test 3 (b) (i): BAM friction apparatus
Parameter:
other: Observations were made for any signs of an explosion
Result:
negative, no explosion
Remarks on result:
other: There were no signs of ignition or explosion. A brown mark on the porcelain plate and peg indicated decomposition.
Test series:
other: Koenen steel tube test
Method:
other: Koenen steel tube test with 6 mm and 2 mm orifice plates
Parameter:
other: Condition of tube on recovery
Result:
negative, no explosion
Remarks on result:
other: The tube was recovered intact.

During the Koenen steel tube tests an orange flame from the orifice was observed and test material was ejected from the orifice. The orange flame self-extinguished 158 - 205 s into the test time.

Interpretation of results:
GHS criteria not met
Conclusions:
BHES- 100X has been determined not to have explosive properties.
Executive summary:

The explosive properties were determined based on Method A 14 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).

The test material was subjected to the following:

1) The BAM fall hammer test which is a test of mechanical sensitivity with respect to shock.

2) The BAM friction test which is a test of mechanical sensitivity with respect to friction.

3) The Koenen steel tube test which is a test of thermal sensitivity.

BHES- 100X has been determined not to have explosive properties.

non explosive

Additional information

Justification for classification or non-classification

BHES- 100X has been determined not to have explosive properties and is therefore not classified.
