Test procedure:

burning rate test: preliminary screening test

Remarks:

test substance melted when approached by the ignition flame

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

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:

HPP 12879-1 is classified as a not readily combustible solid when tested according to UN-MTC Procedure N.1.

Executive summary:

A flammability test according to UN test procedure ‘Recommendations on the Transport of Dangerous Goods - Manual of Tests and Criteria’ (UN-MTC) (Part III, sub-section 33.2.1.4.1, Test N.1 ‘Test method for readily combustible solids’) has been performed. The test substance melted when approached by the ignition flame. The substance did not burn up. The test substance HPP 12879-1 is classified as a not readily combustible solid when tested according to UN-MTC Procedure N.1.

Reference 2

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

Reference 3

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

GLP compliance:

no

Other quality assurance:

ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)

Test procedure:

other: Grewer oven test

Result:

negative outcome (no effect observed)

No safety-relevant exothermic reactions were detected (see field 'illustration'). The wire mesh basket was nearly empty after the measurement. HPP 12879-1 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.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

HPP 12879-1 is not a self-heating substance in the sense of CLP Annex I, 2.11.

Executive summary:

A Grewer oven test according to procedure VDI 2263, Part 1 has been performed. The sample in its delivery state and an inert

reference sample are heated up to 380 °C at a rate of 0.5 K/min in an air flow of about 20 L/h.

No safety-relevant exothermic reactions were detected. Thus, HPP 12879-1 is not a self-heating substance in the sense of CLP Annex I, 2.11.

Description of key information

HPP 12879-1 is classified as a not readily combustible solid when tested according to UN-MTC Procedure N.1.

HPP 12879 -1contains none of the functional groups quoted in UN-MTC (appendix 6, article 5.3) which may react with water to emit flammable gases. Therefore, it can be concluded by expert judgement that HPP 12879-1 does not emit flammable gases in contact with water.

HPP 12879 -1 did not deliver indications of pyrophoric properties during the realization of other tests.

No safety-relevant exothermic reactions were detected. Thus, HPP 12879-1 is not a self-heating substance in the sense of CLP Annex I, 2.11.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

HPP 12879 -1 is not flammable, does not ignite spontaneously with water and air and does not liberate gases in hazardous amounts. Based on the chemical structure and experience in handling and use, pyrophoricity is not expected. The substance does not show self-heating properties. No safety relevant exothermic reactions were detected.

Justification for classification or non-classification

The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 and are therefore conclusive but not sufficient for classification.
