Macrolex Orange R melted on approach of the flame. No ignition and no burning of the substance were seen.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

No ignition and no burning of Macrolex Orange R were observed.

Executive summary:

The test was conducted according to UN-MTC procedure Test N.1 'Test method for readily combustible solids' and in EC A.10, Guideline EC 440/2008.

A preliminary screening test was performed to determine if propagation by burning with flame or smoldering occurs without wetted zone. Macrolex Orange R was formed into a powder train about 250 mm long by about 20 mm wide by about 10 mm high on a non-combustible, non-pourous and low heat-conducting base plate.

Macrolex Orange R melted on approach of the flame. No ignition and no burning of the substance were observed.

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:

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

Flammability:

Macrolex Orange R melted on approach of the flame. No ignition and no burning of the substance were observed.

Pyrophoric properties:

Macrolex Orange R is known to be stable in contact with air at room temperature for prolonged periods of time (days) and did not deliver indications of pyrophoric properties during the realization of other tests.

Contact with water:

Macrolex Orange R does not contain metals or metalloids and hence the classification procedure does not need to be applied.

Self-heating:

According to column 2 of Annex VII to REACH, the study does not have to be conducted if preliminary results exclude self-heating of the substance up to 400 °C (see auto-flammability).

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Based on available data, Macrolex Orange R is not flammable, not pyrophoric, not self-heating and does not emits flammable gases in contact with water. Thus, it does not have to be classified based on GHS criteria.
