Oxidising properties

Link to relevant study record(s)

Reference

Endpoint:

oxidising solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

21 March 1990 to 04 February 1991

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

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

Deviations:

no

GLP compliance:

yes

Specific details on test material used for the study:

Product designation: Monoazo Yellow BG 3247
Identification: FAT 40400/A BG 3247/TV 6

Contact with:

powdered cellulose

Sample tested:

reference mixture (not specified)

Parameter:

maximum burning rate

Result:

2.7 other: mm/s

In all the tested mixtures only smouldering fire was observed. For the 30 % test substance:70 % cellulose mixture and the 50:50 mixture, none of the six test propagated to the first reference mark. For the 40:60 mixture extinction was observed after 50 mm before the second reference mark was reached.

Interpretation of results:

GHS criteria not met

Conclusions:

The test substance has no oxidizing properties.

Executive summary:

In a GLP-compliant study, performed according to EU method A.17, the oxidizing properties of FAT 40400/A were determined. Hot platinum wire (approximately 1000 °C) was used as an ignition source. In all the tested mixtures only smouldering fire was observed. For the 30 % test substance:70 % cellulose mixture and the 50:50 mixture, none of the six test propagated to the first reference mark. For the 40:60 mixture extinction was observed after 50 mm before the second reference mark was reached. The maximum burning rate of the reference mixture barium nitrate/cellulose (60:40) was 2.7 mm/s. Overall, it was 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 test substance has no oxidising properties, so 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.
