Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

no

GLP compliance:

yes

Test procedure:

Remarks:

or specified in description of method (migrated information)

Remarks on result:

other: The test material melted but did not ignite in contact with the test flame

In the preliminary test, the test material melted but did not ignite in contact with the test flame. The substance did not propagate combustion and the burning time over 200 mm could not be determined. Further testing was not required.

Interpretation of results:

non flammable

Remarks:

Migrated information

Conclusions:

Under the conditions of the test, the test material did not propagate combustion. The test material is therefore not classified as highly flammable in relation to its burning characteristics. The study is considered to be reliable, relevant and adequate for risk assessment and classification and labelling purposes.

Executive summary:

The flammability of the test material (burning characteristics) was assessed in accordance with EU Method A.10. Under the conditions of the test, the test material melted and failed to ignite and so further tests were not performed. The test material is therefore not classified as highly flammable in relation to its burning characteristics.

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Type of information:

experimental study

Adequacy of study:

key study

Study period:

17 July 2003 to 22 August 2003

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.12 (Flammability (Contact with Water))

Deviations:

no

GLP compliance:

yes

Step 1: No gas evolved

Step 2: No gas evolved

Step 3: No gas evolved

Step 4:

Sample preparation : Sieved ≤0.5 mm

Room temperature : 21-23 °C

Water temperature: 22 °C

No gas was evolved on contact with water over a period of 7 hours in each of the three tests.

Interpretation of results:

non flammable

Remarks:

Migrated information

Conclusions:

Under the conditions of the test, the test material did not evolve highly flammable gases on contact with water. The test material is therefore not classified as highly flammable in terms of its reactivity with water. The study is considered to be reliable, relevant and adequate for risk assessment and classification and labelling purposes.

Executive summary:

The flammability of the test material (reactivity with water) was assessed in accordance with EU Method A.12. Under the conditions of the test, the test material did not evolve highly flammable gases on contact with water. The test material is therefore not classified as highly flammable in relation to its reactivity with water.

where N = No signs of ignition during dropping or throughout the 5 minute observation period.

Room temperature = 22 ºC

Interpretation of results:

non flammable

Remarks:

Migrated information

Conclusions:

Under the conditions of the test, the test material did not spontaneously ignite on contact with air at ambient temperature. The test material is therefore not classified as highly flammable in terms of its pyrophoric properties. The study is considered to be reliable, relevant and adequate for risk assessment and classification and labelling purposes.

Executive summary:

The flammability of the test material (pyrophoric properties) was assessed in accordance with EU Method A.13. Under the conditions of the test, the test material did not spontaneously ignite on contact with air at ambient temperature. The test material is therefore not classified as highly flammable in relation to its pyrophoric properties.

Description of key information

Flammability (solids) = non flammable, EU Method A.10, Jackson 2003a

Flammability (pyrophoric properties) = non flammable, EU Method A.13, Jackson 2003b

Flammability (contact with water) = non flammable, EU Method A.12, Jackson 2003c

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

The test material was assessed for flammability using three tests to investigate three methods of propagation.

1. The flammability of the test material (burning characteristics) was assessed in accordance with EU Method A.10. Under the conditions of the test, the test material melted and failed to ignite and so further tests were not performed.

2. The flammability of the test material (pyrophoric properties) was assessed in accordance with EU Method A.13. Under the conditions of the test, the test material did not spontaneously ignite on contact with air at ambient temperature.

3. The flammability of the test material (reactivity with water) was assessed in accordance with EU Method A.12. Under the conditions of the test, the test material did not evolve highly flammable gases on contact with water.

Overall, the test material can be concluded to be non-flammable as it did not produce a positive result in any of the three tests performed. All studies were performed in line with GLP and accepted standardised guidelines all with a high standard of reporting. All three studies were assigned a reliability score of Klimisch 1 and considered suitable for assessment as an accurate reflection of the test substance.

The available data is complete and the conclusion, the test substance was non-flammable based on all three studies, was taken forward for risk assessment.

Justification for classification or non-classification

In accordance with Regulation (EC) No. 1272/2008, the test material does not require classification for flammability as it produced negative results in all the flammability tests performed.

In accordance with Directive 2001/59/EC, 2.2, the test material does not require classification for flammability as it produced negative results in all the flammability tests performed.
