Description of key information

The test item ignited after contact with the flame, but after a burning distance of 1.5 cm, the propagating flame died and further combustion of the test item was observed only where the test item was in direct contact with the flame of the burner. When the burner was removed, the flame at the test item died. 

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Key study was performed in order to determine the flammability of zinc methacrylate according to the EU.method A.10 and UN Method N1, 2009: “Test method for readily combustible solids” under GLP.

In the preliminary screening test, the test item was heated with the flame of a teclu burner. The test item ignited, but after a burning distance of 1.5 cm,

the propagating flame died and further combustion of the test item was observed only where the test item was in direct contact with the flame of the burner. When the burner was removed, the flame at the test item died. After cooling down, the test item had turned grey-black.

Therefore, the test item zinc methacrylate should be considered as not highly flammable.

The result has been considered as reliable without restriction because the test was performed in compliance with OECD and EU guidelines giving scientifically valid results

Justification for classification or non-classification

As the substance failed to ignite in the burning rate test (EC A10 method), it is classified as not highly flammable according to Directive 67/548/EEC Annex VI criteria.

The preliminary test in EC A10 method is identical to the one of test N1 of UN manual of tests and criteria (Recommendations on the transport of dangerous goods,4th revised edition, 2008), therefore the result also fulfills criteria for non-classification according to Regulation (EC) No.1272/2008 (CLP)."
