Reference 1

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2020

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)

Version / remarks:

Rev. 6, 2015 Method N1

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

Batch no.: 931-EMP-19004

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

Safety Pre-Test: At contact with the flame, the flame became red-pink. Also, a colourless damp was visible. No melting was observed, and the test item stayed unchanged.

Preliminary Screening Test: In the preliminary screening test following the EU and the UN method, the test item was heated with the flame of a Teclu-burner. Flame colouring to red pink was visible. The test item stayed unchanged. No ignition occurred within two minutes.

RESULTS AND DISCUSSION

No ignition was observed throughout the course of the test.

The test item AM(pfa)4 should be considered as not highly flammable (for EU regulations) and as non-flammable solid (for UN regulations). In lack of flammability, no burning rate determination was possible.

No observations were made which might cause doubts concerning the validity of the study outcome.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

As a result of this experiment, according to UN method N.1 the test item AM(pfa)4 should be considered as not highly flammable (for EU regulations) or non-flammable solid (for UN regulations), respectively.

Executive summary:

In this experiment, according to UN-test method N.1 (EU A.10) first, a safety test was performed. A small amount of the test item was heated on a magnesia groove with a gas burner in order to derive safety precautions.

At contact with the flame, the flame became red-pink. Also, a colourless damp was visible. No melting was observed, and the test item stayed unchanged.

In the preliminary screening test, following the EU and the UN method, the test item was heated with the flame of a Teclu burner. Flame colouring to red pink was visible. The test item stayed unchanged. No ignition occurred within two minutes.

Therefore, the test item AM(pfa)4 should be considered as not highly flammable (for EU regulations) or non-flammable solid (for UN regulations), respectively.

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 experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

Reference 3

Endpoint:

flammable gases

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a solid

Reference 4

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

Description of key information

The substance was tested for flammability of solids, according to UN method N.1 and in result of this the test item AM(pfa)4 should be considered as not highly flammable (for EU regulations) or non-flammable solid (for UN regulations), respectively. From handling and use it is known that the substance is not pyrophoric and that the substance does not react with water, forming flammable gases. In conclusion, the substance is non-flammable.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Neither flammability of solids was observed, nor pyrophoricity or reactivity with water to form flammable gases. Thus, the substance is not subject for classification for flammability according to CLP (Regualtion EC No. 1272/2008).
