Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
experimental study
Adequacy of study:
key study
Study period:
May 2014
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Study conducted to standard UN test guidelines, with possible minor methodological deficiencies, which do not effect the quality of the relevant results
according to guideline
other: UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Fifth revised edition, 2009: Explosives; Series 1 type (b): Koenen Test
2.0 mm orifcace plate used only
GLP compliance:
not specified
thermal sensitivity - Koenen test: diameter of the orifice plate
Remarks on result:
not thermal sensitive if heated under defined confinement

The test results are summarized in the table below. The reactions are characterized in the UN Manual of Tests and Criteria as effect type “O” (i.e. tube unchanged), which is categorized as “no explosion” (considered negative). Each trial produced a flame out of the top of the orifice (approximately 2 feet) that had a burn time of roughly 40 seconds for each trial.

Summary of Koenen Test Results



Conditions and Results


Dibutyl phthalate

1.5-mm orifice: Heating rate of 3.3°C/sec ± 0.3°C, Koenen apparatus within calibration



BMS-589152-01 – Trial 1

2.0-mm orifice; 3.3°C/sec ± 0.3°C; Effect type “O” (i.e. tube unchanged); 5-minute test duration



BMS-589152-01 – Trial 2

2.0-mm orifice; 3.3°C/sec ± 0.3°C; Effect type “O” (i.e. tube unchanged); 5-minute test duration



BMS-589152-01 – Trial 3

2.0-mm orifice; 3.3°C/sec ± 0.3°C; Effect type “O” (i.e. tube unchanged); 5-minute test duration


Interpretation of results:
non explosive
Based on the test results of a limiting diameter of 2.0 mm, BMS-589152-01 sample shows no violent effect on heating under confinement.

Description of key information

Testing on the sample BMS-589152-01 was conducted to characterize its sensitiveness to the effect of intense heat under high confinement using the Koenen test

Based on the test results, sample BMS-589152-01 has shown to have no violent effect on heating under confinement since the limiting diameter is 2.0 mm or less.

Key value for chemical safety assessment

non explosive
