Reference

Reference 1

Endpoint:

oxidising liquids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied

Justification for type of information:

No oxidising properties; Tremain & Atwal; EU Method A.21.

Pressure rise time for the 1:1 mixtures, by mass, of 65 % nitric acid and cellulose

	Test 1	Test 2	Test 3	Test 4	Test 5
Time at 2070 kPagin s	22.785	22.445	22.990	20.065	18.605
Time at 690 kPagin s	18.325	17.425	18.250	16.415	15.085
Pressure rise time in s	4.46	5.02	4.74	3.65	3.52

 

The mean pressure rise time is 4.28 s. All measured values are within the tolerable range of± 30% (2.99 – 5.56 s) of the mean pressure rise time.

*) No increase up to 2070 kPa_gwas detected.

The mean pressure rise time of the tests can not be calculated for thetest item because the pressure limit of2070 kPa_gwas not reached.

The mixture was heated until the bursting disk ruptures or until at least 60 s had elapsed.Due to the fact that the 1:1 mixture, by mass, of test item and cellulose has a pressure rise time higher than that of a 1:1 mixture, by mass, of 65 % nitric acid and cellulose the other mixtures of cellulose with the other reference items had not to be tested. The test item has no oxidising properties.

Interpretation of results:

other: no oxidising properties

Remarks:

Migrated information

Conclusions:

The substance has no oxidising properties.

Executive summary:

The test item has no oxidising properties under the test conditions.

The test item does not meet the classification criteria for oxidizing properties in the sense of the Recommendations on the Transport of Dangerous Goods Division 5.1, Manual of Tests and Criteria, Part 34.4.2 (Test 0.2).

The test item does not meet the classification criteria for oxidizing properties in accordance with Regulation (EC) No. 1272/2008 on the classification, labelling and packaging of substances and mixtures ("CLP Regulation").

The test item has no oxidising properties under the test conditions in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.21.

Description of key information

No oxidising properties; Tremain & Atwal; EU Method A.21. (waiver)

No oxidising properties; Dornhagen (2012); EU Method A.21.

Key value for chemical safety assessment

Oxidising properties:

no

Additional information

The oxidising properties were predicted using Method A21 Oxidising Properties (Liquids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.

The test item is a multi constituent containing two components.

The structures were assessed for chemical groups that would imply oxidising properties. Examples of such groups are nitrates, metal oxides, hypofluorites, difluoroaminopolynitroaryls, perchlorates, bromates and iodites.

There are no groups within the structure that would imply oxidising properties.

Based on the chemical structure the result for the oxidising properties has been predicted negative.

Justification for classification or non-classification

There are no groups within the structure that would imply oxidising properties and therefore based on the chemical structure the result for the oxidising properties has been predicted negative.

The substance is therefore unclassified for oxidising properties.
