- 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:
- pyrophoric solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010-02-01 to 2010-02-17
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP guideline study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.13 (Pyrophoric Properties of Solids and Liquids)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: UN test N.2
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- signed 2009-10-29
- Test procedure:
- ignition time on contact with air
- Remarks:
- Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
- Remarks on result:
- no ignition on contact with air (not further specified)
- Remarks:
- corresponding to 'no' in migrated source record. | Remarks: | Additional remarks: In 6 tests the test item did not ignite during dropping or within 5 minutes of settling.
- Interpretation of results:
- non flammable
- Remarks:
- Migrated information
- Conclusions:
- The test item zinc selenite has no pyrophoric properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.13. /UN test N.2. The test item is not a pyrophoric solid in the sense of Regulation (EC) No. 1272/2008 (CLP Regulation).

- Conclusions:
- Preliminary test: Zinc selenite could not be ignited with a flame. The performance of the main test was therefore not necessary. Zinc selenite is not a flammable solid according to the classification criteria as laid down in Regulation (EC) No. 1272/2008. It is not a highly flammable solid in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.10. and UN test N.1.

Preliminary test:
The test item could not be ignited with a flame. The performance of the main test was therefore not necessary.
Description of key information
The test item zinc selenite could not be ignited with a flame. It is not a highly flammable solid and it has no pyrophoric properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.13. /UN test N.2. It is not flammable in contact with water.
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
The test data (GLP, OECD guideline conform) is reliable without restrictions.
Testing of flammability in contact with water is not considered to be required, because the substance does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable. Furthermore, long-term industrial experience in practical handling of the substance shows that it does not react with water, and recent experimental testing for water solubility has also not reported any formation of gases.
Justification for classification or non-classification
The test item zinc selenite could not be ignited with a flame. The test item is not a flammable solid or a pyrophoric solid in the sense of Regulation (EC) No. 1272/2008 (CLP Regulation). Zinc selenite is not proposed for classification as flammable solid, pyrophoric solid or substance which in contact with water emits flammable gases.
