Zinc selenite

Auto flammability

Link to relevant study record(s)

Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2010-02-18 to 2010-03-01

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:

other: VDI-Richtlinie 2263 (Grewer-Oven screening test)

Deviations:

no

Principles of method if other than guideline:

According to Regulation (EC) No. 1272/2008 (CLP-Regulation) the classification procedure for self-heating substances (based on UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part III, subsection 33.3.1.6, UN test N.4: Test method for self-heating substances) need not be applied if the results of a screening test can be adequately correlated with the classification test and if an appropriate safety margin is applied. Therefore, the Grewer Oven test (VDI guideline 2263, Part 1, 1990, Test methods for the Determination of the Safety Characteristics of Dusts) was performed as a first screening if the test item has self-heating properties.

GLP compliance:

yes (incl. QA statement)

Remarks:

signed 2009-10-29

Remarks on result:

other: No self-ignition of the test item was observed up to 430 °C.

Conclusions:

For zinc selenite, no self-ignition was observed up to 430 °C according to VDI-Richtlinie 2263 (Grewer-Oven). The Grewer-Oven test is a screening test which is sufficient for the evaluation of the test substance as being not self-heating. A main study according to the classification procedure for self-heating substances (according to UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part III, subsection 33.3.1.6, UN test N.4: Test method for self-heating substances) need not be applied. The test item has not to be classified as self-heating substance in the sense of the classification criteria as laid down in Regulation (EC) No. 1272/2008 (CLP Regulation).

Description of key information

For zinc selenite, no self-ignition was observed up to 430 °C according to VDI-Richtlinie 2263 (Grewer-Oven).

Additional information

The test data (GLP, OECD guideline conform) is reliable without restrictions. The Grewer-Oven test is a screening test which is sufficient for the evaluation of the test substance as being not self-heating. A main study according to the classification procedure for self-heating substances (according to UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part III, subsection 33.3.1.6, UN test N.4: Test method for self-heating substances) need not be applied. The test item has not to be classified as self-heating substance in the sense of the classification criteria as laid down in Regulation (EC) No. 1272/2008 (CLP Regulation).
