Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2019

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

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

Version / remarks:

2015

Deviations:

no

GLP compliance:

yes

Specific details on test material used for the study:

Identification: Esacure 3644
Physical Description: Light yellow solid
Purity/Composition: UVCB
Storage Conditions: At room temperature protected from light

Test procedure:

burning rate test: preliminary screening test

Burning time:

0 s

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

In contact with the flame of the gas burner the test item melted and turned into a brown/green residue.  White smoke was observed.  After removal of the ignition source, no propagation of combustion of the test item was observed.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The preliminary screening test was performed for the determination of the flammability of Esacure 3644.
No propagation of combustion of the test item along 200 mm length of the pile within 2 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test item is considered ‘not flammable’.

Executive summary:

The preliminary screening test was performed for the determination of the flammability of Esacure 3644.

No propagation of combustion of the test item along 200 mm length of the pile within 2 minutes was observed.  According to the guidelines, performance of the burning rate test is not required.  Based on the results obtained, the test item is considered ‘not flammable’.

Reference 4

Endpoint:

self-heating substances / mixtures

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

the study does not need to be conducted because the substance is completely molten at 160°C

Description of key information

Study conducted to recognised testing guidelines with GLP certification

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

No propagation of combustion of the test item along 200 mm length of the pile within 2 minutes was observed.  According to the guidelines, performance of the burning rate test is not required.  Based on the results obtained, the test item is considered ‘not flammable’.
