Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
explosive properties of explosives
Type of information:
experimental study
Adequacy of study:
key study
Study period:
from 1988-08-08 to 1989-02-01
Reliability:
1 (reliable without restriction)
Qualifier:
equivalent or similar to guideline
Guideline:
EU Method A.14 (Explosive properties)
Deviations:
not specified
Principles of method if other than guideline:
Testing on explosive properties was conducted by applying:
a) Testing on thermal sensitivity (BAM steel core method): Heating of the test item in a steel tube, closed by orifice plates with differing diameters of hole, to determine whether the substance is liable to explode under conditions of intense heat and defined confinement.
b) BAM Fallhammer:
Subjecting the test substance to the shock from a specified mass dropped from a specified height.

=> The above mentioned methods corresponds uniformly to the apparatus and procedures according to EU method A.14 (Regulation No. 440/2008/EC)
GLP compliance:

a) Testing on thermal sensitivity (BAM steel core method):

Even when applying the smallest diameter (1 mm), the test substance showed no thermal sensitivity

b) BAM Fallhammer:

Applying a shock energy of 50 Joule (10 kg/50 cm), the substance showed no mechanical sensitivity

Interpretation of results:
GHS criteria not met
Conclusions:
As diammonium persulfate showed neither thermal nor mechanical sensitivity, the substance was considered not explosive.
Executive summary:

Applying the BAM steel core and the BAM Fallhammer method, which corresponds uniformly to the apparatus and procedures according to EU method A.14 (Regulation No. 440/2008/EC), diammonium persulfate showed neither thermal nor mechanical sensitivity. Therefore, and also based on experience in handling and use, the substance was considered not explosive.

Description of key information

As diammonium persulfate showed neither thermal nor mechanical sensitivity, the substance was considered not explosive.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Applying the BAM steel core and the BAM Fallhammer method, which corresponds uniformly to the apparatus and procedures according to EU method A.14 (Regulation (EC) no. 440/2008), diammonium persulfate showed neither thermal nor mechanical sensitivity. Therefore, and also based on experience in handling and use, the substance was considered not explosive. Further, company data on dust explosiveness revealed no such properties for the test substance (see: Degussa, 2001)

Justification for classification or non-classification

The available data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Based on the results obtained from the experimental study, from company data as well as on experience in handling and use, diammonium persulfate was not classified with respect to explosiveness according to Regulation 1272/2008/EC (CLP), as amended for the fifteenth time in Regulation (EU) No 2020/1182.
