Type of information:

experimental study

Adequacy of study:

key study

Study period:

2007

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with generally accepted scientific standards and described in sufficient detail

Qualifier:

according to guideline

Guideline:

other:

Version / remarks:

CEI-1241-2-1 Part 2 - Method B "in cloud"

Principles of method if other than guideline:

The temperature is determined in a "Godbert-Greenwald" oven. The powder is suspended in contact with the wall of the heated oven. Then, the detection of the ignition or not of the dust is done.
Several test are realised. In each one, several parameters varie : hoven temperature (in steps of 20°C), mass of powder tested (0.15 - 0.3 - 0.6 g), air pressure of the suspension of the sample (0.15 , 0.3 pr 0.5 bar)

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

Sponsor sample identification : "Ultra - fines Erythritol" / Ineris sample identifiction : 07AA261
Sample received from the Sponsor on 03/01/07
No sample preparation.

Key result

Relative self-ignition temperature:

ca. 440 °C

Conclusions:

The temperature of auto-ignition (in cloud) of the sample is 440°C

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2007

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with generally accepted scientific standards and described in sufficient detail

Remarks:

test performed before

Qualifier:

according to guideline

Guideline:

other: Normalized method : CEI-1241-2-1 Part 2 - Method A - "in layer"

Principles of method if other than guideline:

The temperature of auto-ignition of a layer of the pulverulent product is the minimal temperature of a hot surface for which an ingition occurs in the layer, placed an this surface.
The ignition were considered if we noticed a flare or flames in the material, or if we measured a temperature of 450°C or more, or an increase of 250 K or more compared to the temperature of the hot surface, during the test.

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

Sponsor sample identification : "Ultra - fines Erythritol" / Ineris sample identifiction : 07AA261
Sample received from the Sponsor on 03/01/07

Key result

Relative self-ignition temperature:

>= 400 °C

Remarks on result:

other: 5 mm layer

Conclusions:

The temperature of autoignition "in layer" of the product is > 400°C

Key value for chemical safety assessment
