- Sample tested:
- reference: 3:7 mixture potassium bromate + cellulose
- Parameter:
- mean burning time
- Result:
- 105 s
- Interpretation of results:
- other: non oxidizing
- Conclusions:
- The burning time of the mixtures of Dilithium salicylate with cellulose (4:1 and 1:1) was greater than the burning time of the reference mixture of potassium bromate and cellulose (3:7). Based on the test results the test item does not have to be classified as oxidizing solid.
- Executive summary:
The burning time of the mixtures of the test item, Dilithium salicylate, with cellulose (4:1 and 1:1) was greater than the burning time of the reference mixture of potassium bromate and cellulose (3:7). Based on the test results the test item does not have to be classified as oxidizing solid.
In accordance with the results obtained in UN Test O.1 (Oxidising Properties, Solids) the test item is classified as follows:
UN Transport Regulation
The test item does not have to be classified as oxidizing solid in Division 5.1 according to the UN Transport Regulation.
GHS and EC 1272/2008 (CLP Regulation), Annex 1: 2.14
The test item does not have to be classified as oxidizing solid according to GHS and EC 1272/2008 (CLP Regulation) Annex 1: 2.14.
Reference
The results of the reference mixtures of potassium bromate and cellulose are shown in the below tables.

The burning time of the mixtures of the test item with cellulose (4:1 and 1:1) is greater than the burning time of the reference mixture of potassium bromate and cellulose (3:7). Due to the tests the test item does not have to be classified as oxidizing solid.
Description of key information
The burning time of the mixtures of the test item, Dilithium salicylate, with cellulose (4:1 and 1:1) was greater than the burning time of the reference mixture of potassium bromate and cellulose (3:7). Based on the test results the test item does not have to be classified as oxidizing solid.
In accordance with the results obtained in UN Test O.1 (Oxidising Properties, Solids) the test item is classified as follows:
UN Transport Regulation
The test item does not have to be classified as oxidizing solid in Division 5.1 according to the UN Transport Regulation.
GHS and EC 1272/2008 (CLP Regulation), Annex 1: 2.14
The test item does not have to be classified as oxidizing solid according to GHS and EC 1272/2008 (CLP Regulation) Annex 1: 2.14.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
This study was GLP compliant and followed UN Test O.1. The study was given a reliability rating of 1 (reliable without restrictions).
Justification for classification or non-classification
The burning time of the mixtures of Dilithium salicylate with cellulose (4:1 and 1:1) was greater than the burning time of the reference mixture of potassium bromate and cellulose (3:7). Based on the test results the test item does not have to be classified as oxidizing solid.
