Description of key information
Non flammable
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
Screening Test - Burning behavior, according to the VDI-guideline 2263, part 1.
The test substance is considered as non flammable, because at 100 °C there are only localized combustion and/or glowing, with practically no spreading.
Justification for classification or non-classification
According to the CLP Regulation (EC 1272/2008), 2.7 Section, Flammable Solids, powdered, granular or pasty substances or mixtures shall be classified as readily combustible solids when the time of burning of one or more of the test runs, performed in accordance with the test method described in Part III, sub-section 33.2.1, of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, is less than 45 seconds or the rate of burning is more than 2.2 mm/s.
Alternatively, according to the Guidance on the Application of the CLP Criteria*, the burning index (referred to as ‘class number’ in VDI 2263) as obtained from the Burning Behaviour test (VDI 2263, part 1) may be used. If a burning index of 3 or less is found, the substance should not be classified as a flammable solid and no further testing is required.
A burning index of 3 resulted from the burning behaviour test for Malachite Green.
In conclusion, Malachite Green Oxalate does not meet the criteria to be classified as flammable, according to the CLP Regulation (EC 1272/2008).
