Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2010-10-07 to 2010-10-11

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: Test was performed with a dried residue of a concentrated solution. The substance (Nickel bis (dihydrogen phosphate) is stable in solution only.

Qualifier:

according to guideline

Guideline:

EU Method A.16 (Relative Self-Ignition Temperature for Solids)

GLP compliance:

not specified

Specific details on test material used for the study:

- Name of test material (as cited in study report): Nickel bis (dihydrogen phosphate) dry residue of a concentrated solution
- Substance type: dry residue of a concentrated solution
- Physical state: solid
- Sample preparation: The sample was delivered as concentrated solution (about 40 %). In order to analyse the characteristics of a dried solution which was the purpose of this analysis) the sample was dried with a rotary drying unit under vacuum (50 mbar). During the drying process the liquid solution was turned to a dry salt. The distilled water contained no acidity. The dry residue was crushed with a rotary knife mill to a powder and the complete sample was sieved with a mesh size of 250 µm (recovery 100 %, residual moisture content 17 %).

Key result

Relative self-ignition temperature:

> 400 °C

Remarks on result:

other: The substance does not ignite when heated up to 400 °C

Description of key information

The Self-Ignition Temperature for solids of Nickel bis (dihydrogen phosphate), EINECS 242-522-3 (dry residue of a concentrated solution) was determined according to the test method A. 16. as described in the Council Regulation (EC) No 440/2008.

No self-ignition was observed up to a heating temperature of 400 °C.
