Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
