Reference
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Deviations:
no
Principles of method if other than guideline:
The test was performed as stipulated in UN-MTC procedure Test N.1 ‘Test method for readily combustible solids’.
GLP compliance:
yes
Specific details on test material used for the study:
Batch number: CHC 005
Date of receipt: 2016-08-22
Expiry date: 2021-07-19

Content:
1,4-Dichloro-5,8-dihydroxyanthraquinone: 77.59 %
Isomer of 1,4-Dichloro-5,8-dihydroxyanthraquinone: 9.06 %
C14H8O4: 1.82 %
C14H5O4Cl3: 2.58 %
C14H5O4Cl3: 2.00 %
Components < 1 % (sum of 5): 1.82 %
Sulphated ash: 4.60 %
Water: 0.42 %

Physical condition: Solid
Test material form: Powder
Storage: Room temperature
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
Remarks:
not readily combustible solid

No reference substances were applied for the tests.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
1,4-Dichloro-5,8-dihydroxyanthraquinone is not readily combustible solid according to UN-MTC procedure Test N.1 ‘Test method for readily combustible solids’.
Executive summary:

The test was performed as stipulated in UN-MTC procedure Test N.1 ‘Test method for readily combustible solids’.

A preliminary screening test was performed to determine if propagation by burning with flame or smoldering occurs without wetted zone. The substance was formed into a powder train about 250 mm long by about 20 mm wide by about 10 mm high on a non-combustible, nonporous and low heat-conducting base plate. If propagation over 200 mm of the train occurs within a specified time then the full test program to determine the burning rate is carried out.

The substance was measured in its delivery state. The test substance melted when being approached by the ignition flame. The substance did not burn up. No further testing was required.
