Description of key information

Burning number BZ:

- at room temperature BZ 1

- at 100 °C BZ 3

GHS / CLP Regulation EC 1272/2008 Annex 1: 2.7:

The test item does not have to be classified as flammable solid according to GHS or CLP Regulation EC 1272/2008 Annex 1: 2.7, respectively.

UN Transport Regulation:

The test item does not have to be classified as readily combustible solid in class 4, division 4.1 according to the UN Transport Regulation.

The test item is not a highly flammable solid.

No pyrophoricity.

No flammability on contact with water.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The determination of the burning number was performed according to the guideline VDl 2263, sheet 1.

Justification for classification or non-classification

The burning number of the test item at room temperature was determined to be BZ 1 (No ignition).

The burning number of the test item at an elevated temperature of 100 °C was determined to be BZ 3 (Localised combustion or glowing with practically no spreading).

Therefore, neither classification as flammable solid, nor as pyrophoric solid or substance which, in contact with water, emits flammable gases, are warranted.
