Principles of method if other than guideline:

Grewer oven test

GLP compliance:

no

Specific details on test material used for the study:

Batch No.: LAM-2487-3
Expiry date: 2021-05-28

Key result

Test procedure:

other: Grewer oven test

Max. temp. reached:

359

Result:

negative outcome (no effect observed)

The temperature of the solid test item and the temperature of the reference substance (graphite) do not differ until approx. 160 °C. At this point a slightly endothermic peak was observed followed by a larger endothermic event. Around 260 °C a very low exothermic event was recorded. Additional heating until 359 °C did not lead to a difference in the temperature profile of the test item and the reference substance.

The classification procedure for self-heating substances or mixtures does not need to be applied if the results of a screening test can be adequately correlated with the classification test and an appropriate safety margin is applied: The Grewer oven test (VDI guideline 2263, Part 1, 1990, Test methods for the Determination of the Safety Characteristics of Dusts) with an onset temperature 80 K above the reference temperature for a volume of 1 L.

This onset temperature is equal to or greater than 220 °C.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item is not a self-heating substance.

Executive summary:

Based on the data of the Grewer oven test, the test item is not classified as self-heating substance according to the CLP-regulation.

Reference 2

Endpoint:

pyrophoric solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Reference 3

Endpoint:

pyrophoric liquids

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a solid

Reference 4

Endpoint:

flammable gases

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a solid

Reference 5

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 organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied

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

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2021-05-03

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study without detailed documentation

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)

GLP compliance:

no

Specific details on test material used for the study:

CAS No.: 199387-97-8
Purity: 100 area%
Batch No.: LAM-2487-3
Expiry date: 2021-05-28

Key result

Test procedure:

burning rate test over 100 mm length

Remarks on result:

substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

After ignition of the pile on the “left end” only local melting of the solid substance was observed. No distribution of a decomposition front was recorded.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item is not a flammable solid.

Executive summary:

Based on the behavior of the test item at the UN test N.1, this solid substance must not be classified as flammable solid according to the CLP-regulation.

Description of key information

Based on the behavior of the test item at the UN test N.1, this solid substance must not be classified as flammable solid according to the CLP-regulation.

The data of the Grewer oven test indicate, that the test item is not classified as self-heating substance according to the CLP-regulation. 

The substance is known to be stable in contact with air at room temperature for prolonged periods of time and hence is not considered pyrophoric. Experience in production and handling shows, that the substance does not emit flammable gases in contact with water.

 

Key value for chemical safety assessment
