Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.17 (Oxidising Properties (Solids))

Deviations:

not specified

GLP compliance:

yes

Specific details on test material used for the study:

Product designation: Monoazo Yellow TZ 2382
Identification: FAT 40224/C
Vers. 10/86 Op. 1/86

Contact with:

powdered cellulose

Sample tested:

test mixture (not specified)

Parameter:

maximum burning rate

Result:

1.1 mm/s

Sample tested:

reference mixture (not specified)

Parameter:

maximum burning rate

Result:

3.7 mm/s

The 10 % test subtance: 90 % cellulose mixture showed a maximum burning rate of 1.1 mm/s, but only 4 out of 6 tests propagated to the second reference mark. Irregular burning with flame was observed. In the other mixtures none of the 6 tests propagated to second reference mark. Extinction after 0-55 mm was observed.

Interpretation of results:

GHS criteria not met

Conclusions:

FAT 40224/C has no oxidizing properties.

Executive summary:

In a GLP-compliant study with FAT 40224/C, performed according to EU method A.17, the oxidising properties of the test substance were determined. Hot platinum wire (approximately 1000 °C) was used as an ignition source. The 10 % test subtance : 90 % cellulose mixture showed a maximum burning rate of 1.1 mm/s, but only 4 out of 6 tests propagated to the second reference mark. Irregular burning with flame was observed. In the other mixtures none of the 6 tests propagated to the second reference mark. Extinction after 0-55 mm was observed. The maximum burning rate of the reference mixture barium nitrate/cellulose (60:40) was 3.4 mm/s. Therefore, it could be concluded that the test substance had no oxidizing properties.

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Justification for classification or non-classification

As the substance has no oxidising properties, it does not need to be classified as per the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
