- experimental study
- Adequacy of study:
- key study
- Study period:
- 09. Apr. 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.21 (Oxidising Properties (Liquids))
- Version / remarks:
- EU-Guideline A.21 “Oxidising Properties (Liquids)“, of 30 May 2008 published on 31 May 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- No further details specified in the study report.
- Contact with:
- powdered cellulose
- Duration of test (contact time):
- 60 s
- Key result
- Sample tested:
- test mixture 1:1
- Parameter:
- mean pressure rise time
- Remarks on result:
- other: In all five determination, a pressure rise above 2070 kPa was detected but it took much more time than any reference mixture.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item LUMULSE GMT-K is considered as not oxidising, as the increase in pressure took place very slowly, taking much more time than the reference mixture.
- Executive summary:
Determination of the oxidising properties of LUMULSE GMT-K according to EU A.21
Findings and Results:
Five determinations were performed with the test item LUMULSE GMT-K, using a mixture with cellulose.
In all five determination, a pressure rise above 2070 kPa was detected but it took much more time than any reference mixture.
The reference mixture of cellulose and nitric acid (65 %) showed a fast increase above 2070 kPa within 3.835 seconds.
Therefore, LUMULSE GMT-K should not be classified as oxidizing liquid.

Description of key information
LUMULSE GMT-K should not be classified as oxidizing liquid.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Five determinations were performed with the test item LUMULSE GMT-K, using a mixture with cellulose.
In all five determination, a pressure rise above 2070 kPa was detected but it took much more time than any reference mixture.
The reference mixture of cellulose and nitric acid (65 %) showed a fast increase above 2070 kPa within 3.835 seconds.
Therefore, LUMULSE GMT-K should not be classified as oxidizing liquid.
Justification for classification or non-classification
In all five determination, a pressure rise above 2070 kPa was detected but it took much more time than any reference mixture.
Therefore, LUMULSE GMT-K should not be classified as oxidizing liquid.
