Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Version / remarks:

European Commission Regulation (EC) No. 440/2008

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

Test item: WARADUR LG
Batch No.: W00004534
Expiry date: April 11, 2018
Certificate: Certificate of analysis No. 28657 dated April 23, 2013
The test item was tested as received. No further preliminary treatment such as drying or milling was performed. The results given in this report only apply to the tested sample.

Key result

Test procedure:

burning rate test: preliminary screening test

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

Preliminary test

The test item could not be ignited with a flame. The test item melted. The performance of the main test was not necessary.

Final results

The test item is not a highly flammable solid in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.10.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Flammable solids (EU method A.10): not highly flammable according to A.10 - no classification requirements with regard to flammable solids

Executive summary:

Flammability (solids) was tested in a reliable study performed according to EU method A.10 compliant with GLP (RL 1).

In the preliminary test the burning behaviour over a distance of 200 mm was measured. The pile did not ignite after 2 min of contact with the flame. Rather, the test item melted.

As such, according to EU method A.10 the performance of the main test was not necessary and the test item Waradur LG was determined to be not a highly flammable solid in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.10.

In consequence, there are no classification requirements with regard to flammable solids according to REGULATION (EC) No. 1272/2008 (CLP) in conjunction with ECHA guidance document R.7a.

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:

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 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 completely molten at 160°C

Description of key information

No classification requirements with regard to flammability or self-heating properties.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Flammability (solids) was tested in a reliable study performed according to EU method A.10 compliant with GLP (RL 1).

In the preliminary test the burning behaviour over a distance of 200 mm was measured. The pile did not ignite after 2 min of contact with the flame. Rather, the test item melted.

As such, according to EU method A.10 the performance of the main test was not necessary and the test item Waradur LG was determined to be not a highly flammable solid in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.10.

In consequence, there are no classification requirements with regard to flammable solids according to REGULATION (EC) No. 1272/2008 (CLP) in conjunction with ECHA guidance document R.7a.

Justification for classification or non-classification

• Flammable solids (EU method A.10): not highly flammable according to A.10 - no classification requirements with regard to flammable solids
• Pyrophoric properties: Experience from the handling and use of the substance allows to exclude pyrophoric properties (according to CLP Regulation, Annex 1, Part 2, section 2.10.4.1)
• Substances / mixtures which in contact with water emit flammable gases: No testing required as screening information allows to exclude this property (according to CLP Regulation, Annex I, part 2, section 2.12.4): Experience from the handling and use of the substance allows to exclude reaction with water to emit flammable gases; the chemical structure of the substance or mixture does not contain metals or metalloids.
• Self-heating properties: According to the Guidance on the Application of the CLP Criteria (ECHA-17-G-21-EN, July 2017), "Substances or mixtures with a low melting point (< 160 °C) should not be considered for classification in this class since the melting process is endothermic and the substance-air surface is drastically reduced." The melting range was determined for the substance (OECD 102; DSC) at ambient pressure (ca. 1013 hPa): 51.50 °C to ca. 85°C.
