2-3 seconds, glowed under the ignition source and colored black. Underneath the black surface the unaltered test item/cellulose mixture remained. The barium nitrate/cellulose mixture during the same test burned for 66 seconds with a sizzling flame.
In order to confirm the results from the preliminary test, a main test was performed. For all prepared Acid Yellow RN 2903/cellulose mixtures only surface burning or no burning was observed and therefore no burning rates could be calculated. Therefore the test was stopped according to the guideline. In comparison: the fastest barium nitrate/cellulose mixture contained 50% barium nitrate.
Details of the individual measurements are given in Table 1 and Table 2.

RESULTS AND DISCUSSION
The determination of the oxidizing properties of Acid Yellow RN 2903 was performed in
accordance with the EEC Directive 92/69, EEC Publication No. L383, December 1992 and
Council Regulation (EC) No. 440/2008, Methods for the determination of physico-chemical
properties, A.17 “Oxidizing Properties (solids)”.
During the preliminary test the Acid Yellow RN 2903/cellulose mixture only burned for about
2-3 seconds, glowed under the ignition source and colored black. Underneath the black surface
the unaltered test item/cellulose mixture remained. The barium nitrate/cellulose mixture during
the same test burned for 66 seconds with a sizzling flame.
In order to confirm the results from the preliminary test, a main test was performed. For all
prepared Acid Yellow RN 2903/cellulose mixtures only surface burning or no burning was
observed and therefore no burning rates could be calculated. Therefore the test was stopped
according to the guideline. In comparison: the fastest barium nitrate/cellulose mixture contained
50% barium nitrate. Details of the individual measurements are given in Table 1andTable 2 (see above).
In conclusion, Acid Yellow RN 2903 has no oxidizing properties.
Applicant's summary and conclusion
- Interpretation of results:
- other: no oxidising properties
- Remarks:
- Migrated information
- Conclusions:
- Acid Yellow RN 2903 is considered to have no oxidizing properties.
- Executive summary:
Acid Yellow RN 2903 is considered to have no oxidizing properties because all test item/cellulose mixtures only showed surface burning or no burning. Therefore no burning rates were calculated.
