Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

2 min

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

Remarks:

When approached by the ignition flame the test item melted. No further testing was required.

The substance in its delivery state was measured. The test substance melted when approached by the ignition flame. The substance did not burn up. No further testing was required.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Epoxid-Valerat is not a flammable solid.

Executive summary:

Epoxid-Valerat is not a flammable solid. Epoxid-Valerat is classified as a not readily combustible solid when tested according to UN-MTC Procedure N.1.

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

other:

Key result

Test procedure:

other: Expert statement

Remarks on result:

not measured/tested

Remarks:

The substance did not deliver indications of pyrophoric properties during the realization of other tests. The determination acc. to UN-MTC Procedure N.2 is not necessary.

Result:

negative outcome (no effect observed)

Remarks on result:

other: The sample in its delivery state was tested.

Remarks:

No exothermic effects were determined up to the point at which the test substance melted. The wire mesh basket was empty after the measurement.

No exothermic effects were determined up to the point at which the test substance melted. The wire mesh basket was empty after the measurement.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Epoxid-Valerat is not a self-heating substance.

Executive summary:

The test was performed as stipulated in test procedure VDI 2263, Part 1 ‘Test Methods for the Determination of the Safety Characteristic of Dusts’. The sample in its delivery state and an inert reference sample are heated up to 420 °C at a rate of 0.5 K/min in an air flow of about 20 L/h.

No exothermic effects were determined up to the point at which Epoxid-Valerat melted. The wire mesh basket was empty after the measurement. Thus, Epoxid-Valerat is not a self-heating substance.

Reference 4

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

Description of key information

a.) Flammability: Epoxid-Valerat is a not readily combustible solid according to UN N.1.

b.) Pyrophoric properties: Epoxid-Valerat has no pyrophoric properties and is in the sense of the CLP-Directive a non pyrophoric solid. The determination according to UN-MTC Procedure N.2 is not necessary.

c.) Self-heating substances: Epoxid-Valerat is not a self-heating substance in the sense of CLP Annex I, 2.11. The determination according to UN-MTC Procedure N.4 (Bowes-Cameron-Cage-Test) is not necessary.

d.) Contact with water: A review of the structure suggests that there are no chemical groups present that would imply pyrophoric properties or flammability on contact with water. A review of handling and use implies no pyrophoric properties or flammability on contact with water. Testing according to UN Procedure N.5 is not necessary.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Based on the available information, Epoxid-Valerat is not classified as flammable, pyroporic, self-heating or reactive with water.
