- guideline study
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
- Version / remarks:
- revision 6, 2015
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- Test item: Reaction mass of copper oxide and manganese dioxide
Batch No.: #6098; #6116; #6118; #6123; #6139 (mixture of five batches, homogenised)
Content: 70.26 % Manganese dioxide, 22.16 % Copper oxide
Physical state: Brown-black solid
Storage conditions: Ambient temperature (10 °C to 30 °C)
Expiry date: August 17, 2021
Certificate: Certificate of analysis dated March 07, 2017 from MSA, Berlin, Germany
The test item was tested as received. No further preliminary treatment such as drying or milling was performed. - Key result
- 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
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- No classification requirements exist for the submission substance with regard to propertiy flammable solids.
- Executive summary:
The submission substance was tested for flammability of solids according to UN test-method N.1 (UN Manual of Test and Criterita, revision 6, 2015) compliant to GLP.
In the preliminary test, the test item could not be ignited with a flame. In consequence, the performance of the main test was not necessary.
In conclusion, the test item is not a readily combustible solid in the sense of UN Manual of Test and Criteria, Method N.1.
The test item is not a flammable solid according to chapter 2.7 of the GHS (CLP) regulations (1).
(1) Chapter 2.7 of the UN Globally harmonised system of classification and labelling of chemicals (GHS), 6th revised edition, 2015 (UN GHS) and also chapter 2.7 in the CLP regulation 1272/2008 (EU GHS).
- Endpoint:
- substances / mixtures which in contact with water emit flammable gases
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
- Endpoint:
- pyrophoric solids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
- Endpoint:
- self-heating substances / mixtures
- Data waiving:
- other justification

UN N.1 -Test on flammability of solids:
Preliminary test:
The test item could not be ignited with a flame. The performance of the main test was not necessary.
Supplemental explanation: The test item is an inorganic metal oxide. Therefore the test item is not to be assessed and tested as metal.
Description of key information
No classification requirements exist for the submission substance with regard to any of the following properties:
- flammable solids (UN-test N1; RL1; 2017)
- pyrophoric solids
- self-heating substances / mixtures
- substances / mixtures which in contact with water emit flammable gases
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
The submission substance was tested for flammability of solids according to UN test-method N.1 (UN Manual of Test and Criteria, revision 6, 2015) compliant to GLP.
In the preliminary test, the test item could not be ignited with a flame. In consequence, the performance of the main test was not necessary.
In conclusion, the test item is not a readily combustible solid in the sense of UN Manual of Test and Criteria, Method N.1.
The test item is not a flammable solid according to chapter 2.7 of the GHS (CLP) regulations (1).
Further, experience from the handling and use of the substance allows to exclude pyrophoric properties (according to CLP Regulation, Annex 1, Part 2, section 2.10.4.1) as well as reaction with water to emit flammable gases (according to CLP Regulation, Annex I, part 2, section 2.12.4).
From the results of a screening test (Grever-oven test), self-heating properties can be excluded.
Overall conclusion with regard to classification and labelling:
No classification requirements exist for the submission substance with regard to any of the following properties:
- flammable solids
- pyrophoric solids
- self-heating substances / mixtures
- substances / mixtures which in contact with water emit flammable gases.
