Flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods
- 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)
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- ca. 2 min
- 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:
- Based on the results of this study, the test item not to be classified as ‘flammable solid’ according to GHS / CLP Regulation EC 1272/2008 Annex 1: 2.7 and not as ‘highly flammable solid’ according to Regulation EC No. 440/2008 and Directive 67/548/EEC. The test item has to be classified as ‘Not readily combustible solid of Division 4.1’ in the sense of the test guideline UN Test N.1.
- Executive summary:
The flammability of the test item was determined according to UN Test N.1 on 2018-01-24 at the test facility Noack Laboratorien GmbH. The flammability of the pulverized test item was determined by ignition of a cluster with a length of 250 mm and a triangular cross-section of 10 mm height and 20 mm width with the hot flame of a gas burner.The test item was not flammable within 2 minutes by the flame of a butane gas burner within the ignition zone (the first 50 mm of the formed test item).
Based on the results of this study, the test item not to be classified as ‘flammable solid’ according to GHS / CLP Regulation EC 1272/2008 Annex 1: 2.7 and not as ‘highly flammable solid’ according to Regulation EC No. 440/2008 and Directive 67/548/EEC. The test item has to be classified as ‘Not readily combustible solid of Division 4.1’ in the sense of the test guideline UN Test N.1.

Additional information
Justification for classification or non-classification
The flammability of the test item was determined according to UN Test N.1 on 2018-01-24 at the test facility Noack Laboratorien GmbH. The flammability of the pulverized test item wasdetermined by ignition of a cluster with a length of 250 mm and a triangular cross-section of 10 mm height and 20 mm width with the hot flame of a gas burner.The test item was not flammable within 2 minutes by the flame of a butane gas burner within the ignition zone (the first 50 mm of the formed test item).
