Reference
Results
Preliminary Test
The test item did not ignite at room temperature, the test item melted. Only the molten mass burned partly local and partly with propagation of flame for 5 minutes over a distance of 170 mm.
Main Test
In the preliminary test the test item could not be ignited by a flame. Therefore, the performance of the main test was not necessary. Only the molten mass burned partly local and partly with propagation of flame for 5 minutes over a distance of 170 mm.
Final Results
The test item could not be ignited applying a flame as ignition source for at least 2 minutes. The test item melted.
The test item is classified as follows:
UN Transport Regulation:The product has not to be classified asreadily combustible solidin class 4.1 according to the UN Transport Regulation.
GHS (CLP Regulation EC 1272/2008: Annex 1: 2.7):The product has not to be classified asflammable solidaccording to GHS / CLP Regulation EC 1272/2008 Annex 1: 2.7.
Description of key information
non flammable
no pyrophoricity
no flammability on contact with water
not self-heating
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
The substance is not flammable according to UN Test N.1.
Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.
The substance is completely molten at a temperature well below 160 °C and therefore shows not self-heating behaviour if it is not absorbed on a large surface.
Justification for classification or non-classification
The substance is not flammable according to UN Test N.1 and has not to be classified as flammable solid according to GHS / CLP Regulation EC 1272/2008 Annex 1: 2.7.
The available data on flammability in contact with water, pyrophoricity and self-heating of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification.
Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.
The substance is completely molten at a temperature well below 160 °C and therefore shows not self-heating behaviour if it is not absorbed on a large surface.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
