Auto flammability

Link to relevant study record(s)

Reference

Reference 1

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

November 1999

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

test procedure in accordance with national standard methods with acceptable restrictions

Qualifier:

equivalent or similar to guideline

Guideline:

other: no guideline reported

Principles of method if other than guideline:

Deposited dust: This test determines the ignition temperature of a dry product on a hot surface. For a description of the method see "any other information on materials and methods".

GLP compliance:

not specified

Key result

Relative self-ignition temperature:

> 360 °C

Remarks on result:

no self ignition observed under the test conditions

At the highest tested temperature (360°C) there was no reaction observed for deposited Creatinine dust.

Conclusions:

No auto-ignition of deposited Creatinine dust occurred on surfaces until 360°C.

Executive summary:

The test determines the ignition temperature of a deposited dusty test substance on hot surfaces. The test is conducted according to the test protocol. The surface area of the substance is increased intentionally in this test by preparing the test substance accordingly to simulate the deposited dusty properties. The ignition temperature of deposited dusty test material is expected to be lower than the ignition temperature of the solid with larger particle diameters. At the hottest temperature in this test (360°C) there was no reaction observed for deposited Creatinine dust.

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

supporting study

Study period:

November 1999

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

test procedure in accordance with national standard methods with acceptable restrictions

Qualifier:

equivalent or similar to guideline

Guideline:

other: no guideline reported

Principles of method if other than guideline:

Dispersed dust: This test determines the ignition temperature of flammable dispersed dusty substances on hot surfaces. See section "any other information on materials and methods" for detailed description of the method.

GLP compliance:

not specified

Key result

Relative self-ignition temperature:

> 600 °C

Remarks on result:

no self ignition observed under the test conditions

At the highest tested temperature (600°C) there was no reaction observed for dispersed Creatinine dust.

Conclusions:

No auto-ignition of dispersed Creatinine dust occurred until 600°C.

Executive summary:

The test determines the ignition temperature of a dispersed dusty test substance on hot surfaces. The test is conducted according to a test protocol. The surface area of the substance is increased intentionally in this test by preparing the test substance accordingly to simulate the dispersed dusty properties. The ignition temperature of dispersed dusty test material is expected to be significantly lower than the ignition temperature of the solid with larger particle diameters. Until 600 °C there was no reaction observed for dispersed Creatinine dust.

Description of key information

Two tests for dusty Creatinine are available evaluating the auto-flammability on a hot surface for deposited and dispersed Creatininine.

No auto-ignition of deposited Creatinine dust occurred on surfaces until 360°C. Also no-auto-ignition of dispersed Creatinine dust was observed until 600 °C.

Additional information

The test for deposited Creatinine (100 mg) was conducted for 5 min on a hot surface up to 360 °C. No reaction was observed.

The test for dispersed Creatinine was conducted on a surface up to 600 °C. No reaction was observed.
