Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- other information
- 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
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- Batch number: CHA2016
Physical condition: Orange powder
Expiration date: 2017-09-16 - 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:
- Sample melted during approaching of the burner flame. Sample burned after removing of the burner flame for about 1 s, then the test sample extinguished. A complete combustion of the powder train was not observed.
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- Dihydrochinizarin is not readily combustible according to UN N.1.
- Executive summary:
The test was performed as stipulated in UN-MTC*) procedure Test N.1 (‘Test method for readily combustible solids’).
During the preliminary screening test the Dihydrochinizarin melted during approaching of the burner flame. The sample burned after removing of the burner flame for about 1 s, then the test sample extinguished. A complete combustion of the powder train was not observed.
The performance of the complete test program was not necessary, as Dihydrochinizarin is not readily combustible.
- Endpoint:
- self-heating substances / mixtures
- Type of information:
- experimental study
- Adequacy of study:
- other information
- 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.4 (Test method for self-heating substances)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Test procedure:
- other: Dihydrochinizarin was placed in a wire basket with 8 mL volume in an oven at room temperature. Heating rate: 0.5 K/min up to 420 °C
- Max. temp. reached:
- 400
- Result:
- negative outcome (no effect observed)
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- Dihydrochinizarin has no self-heating potenial.
- Executive summary:
The test was performed as stipulated in UN-MTC (Recommendations on the Transport of Dangerous Goods - Manual of Test and Criteria, 6th revised edition, 2015) procedure 4. In the temperature/time diagram no exothermic effect was observed. At the end of the test the basket was empty. According to appendix 6, chapter 5.2.2 of UN-MTC no additional tests are necessary.
Therefore, Dihydrochinizarin has no self-heating potential.

Description of key information
Dihydrochinizarin is a non-combustable solid according to UN-MTC procedure test N.1 (‘Test method for readily combustible solids’) and did not deliver any indications of pyrophoric properties during the realization of the burning rate test N.1. Therefore the determination according to UN-MTC procedure N.2 is not necessary. Dihydrochinizarin has no self-heating potential according to UN-MTC procedure N.4. The chemical structure of Dihydrochinizarin contains no metals or metalloids. According to UN-MTC Appendix 6 point 5.3 the testing procedure N.5 is not necessary.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
a) Flammability: Dihydrochinizarin is not readily combustable according to UN-MTC procedure N.1.
b) Pyrophoric solids: Dihydrochinizarin did not deliver any indications of pyrophoric properties during the realization of other tests, specially during performing the burning rate test N.1. Testing according to UNMTC procedure N.2 is not necessary.
c) Self-heating substances: Dihydrochinizarin has no self-heating potential according to UN-MTC procedure N.4.
d) Contact with water: The chemical structure of Dihydrochinizarin contains no metals or metalloids. According to UN-MTC Appendix 6 point 5.3 the testing procedure N.5 is not necessary.
Justification for classification or non-classification
Dihydrochinizarin is a not readily combustible solid, does not emit flammable gases in contact with water and does not exhibit pyrophoric or self-heating properties.
Bases on the available information Dihydrochinizarin is not classified for physical hazards according to Regulation (EC) NO. 1272/2008 (CLP).
