Reference

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

1993-04-19 to 1993-04-19

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

no

GLP compliance:

yes

Key result

Test procedure:

burning time over 250 mm for metal powders or metal alloys

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

Interpretation of results:

not classified based on GHS criteria

Conclusions:

In a GLP study conducted according to EU Method A.10, trisodium EDDS could not be ignited by a flame.

Executive summary:

In a GLP study conducted according to EU Method A.10, the flammability of trisodium EDDS was examined by the application of a flame to a strip of the solid material 250 mm long, 20 mm wide and 10 mm high. The test material failed to ignite and blackened in contact with the flame. Trisodium EDDS is considered 'not highly flammable' according to the test conditions, and would not be classified as a flammable solid according to EU CLP or DSD regulations.

Additional information

In a GLP study conducted according to EU Method A.10, the flammability of trisodium EDDS was examined by the application of a flame to a strip of the solid material (250 mm long, 20 mm wide and 10 mm high). The test material failed to ignite and blackened in contact with the flame. Trisodium EDDS is considered 'not highly flammable' according to the test conditions (van Helvoirt, 1993e).

In addition, in a GLP study conducted according to EU Method A.10, the flammability of EDDS acid was examined on six occasions by the application of a flame or hot wire to a strip of the powdered material (250 mm long, 20 mm wide and 10 mm high). The test material ignited briefly, but no flame propagation occurred. EDDS acid is considered 'not highly flammable' according to the test conditions (Gair et al. 2002). [Data on EDDS free acid is considered relevant to use for predicting the flammability of trisodium EDDS, and is acceptable for using as read-across information.]

Justification for classification or non-classification

Trisodium EDDS was not easily ignited by brief contact with an ignition source in a reliable test and, therefore, would not be classified as a flammable solid according to EU CLP or DSD regulations.
