Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 15 September 2016 to 31 August 2016
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Key result
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
Remarks:
the test item glowed with the contact of the flame
Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item is not classified as a flammable solid of Division 4.1
Executive summary:

The flammability of the test item was determined according to recognized guideline (UN Test N.1) and under GLP. No deviation from the guideline was observed during the test.

Based on the preliminary test, the test item is not classified as flammable solid of Division 4.1.

Endpoint:
pyrophoric solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
Endpoint:
self-heating substances / mixtures
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
other:
Reason / purpose for cross-reference:
data waiving: supporting information

Description of key information

The flammability of lutetium oxalate was investigated using the UN N.1 test method in a GLP study. Based on the negative result, the test item is not considered to be a flammable solid.

Furthermore, based on experience in day-to-day handling and use, the test item is not considered pyrophoric or not to emit flammable gases in contact with water. Finally, since no relative self-ignition temperature could be determined up to 400°C in a test performed according to the EU A.16 method, the substance is not self-heating either.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

According to a UN N.1 test, the substance is not classified as a flammable solid of Division 4.1 and is not assigned to any packing group. Furthermore, the test item is considered not to be pyrophoric or self-heating and not to emit flammable gases in contact with water.

Justification for classification or non-classification

According to a UN N.1 test, the substance is not classified as a flammable solid of Division 4.1 and is not assigned to any packing group. Furthermore, the test item is considered not to be pyrophoric or self-heating and not to emit flammable gases in contact with water.
