Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

> 2 min

Remarks on result:

substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

Preliminary Test

The test item did not ignite at room temperature using a flame as ignition source being applied for at least 2 minutes.

Main Test

ln the preliminary test the test item could not be ignited by a flame. Therefore, the performance of the main test was not necessary.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

In conclusion, the test item Magnesium-(L)-hydrogen aspartate 2-hydrate could not be ignited applying a flame as ignition source for at least 2 minutes. The test item remained unchanged. Thus, the main test does not need to be performed. The test item has to be classified neither as readily combustible solid in Class 4, Division 4.1 according to the UN Transport Regulation nor as flammable so/id according to GHS / CLP Regulation EC 1272/2008 Annex 1: 2.7.

Executive summary:

The test item was tested according to Regulation EC No. 440/2008, Part A, A.10., UN Transport Regulation (Class 4, Division 4.1) and GHS / CLP Regulation EC 1272/2008 (Annex 1: 2.7), in order to assess whether the test item is highly flammable solid. Therefore, the test item was filled in a mould of a length of 250 mm, an inner height of 10 mm and a thickness of 20 mm.

As ignition source, a flame was applied on the test item until it ignites or for at least 2 minutes (for metal dusts and metal alloys 5 minutes). Since the test item could not be ignited by a flame the main test was not performed. The test item is not classified as highly flammable according to Regulation EC No. 440/2008, Part A, A.10., UN Transport Regulation (Class 4, Division 4.1) and GHS / CLP Regulation EC 1272/2008 (Annex 1: 2.7).

Description of key information

The test item was tested for flammability according to Regulation EC No. 440/2008 Method A.10. Flammability of Solids and Recommendations on the TRANSPORT OF DANGEROUS GOODS: Manual of

Tests and Criteria, 6th edition, New York and Geneva, 2015: Class 4, Division 4.1: Readily Combustible Solids, Test N.1. Since the test item could not be ignited applying a flame as ignition source for at least 2 minutes, the substance was not classified.

Key value for chemical safety assessment

Flammability:
