no ignition within 5 minutes

Key result

Test procedure:

effect on filter paper

Temp.:

23 °C

Remarks on result:

other: The test item did not spontaneously ignite or produce charring of the filter paper.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item is non-pyrophoric.

Executive summary:

Pyrophoric properties of the test item were determined according to EU Method A.13 (Pyrophoric Properties of Solids and Liquids).

 

In test 1, the test item (5 mL) was poured onto a Pyrex dish filled with diatomaceous earth (Kieselguhr) to a depth of 0.5 cm. Six replicate tests were performed at 23 °C.The test item did not spontaneously ignite within five minutes in any of the replicate tests.

In test 2, the test item (0.5 mL) was placed on an indented filter paper. Three replicate tests were performed at 23 °C. The test item did not spontaneously ignite or produce charring of the filter paper.

 

In conclusion, the test item is non-pyrophoric.

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Type of information:

experimental study

Adequacy of study:

key study

Study period:

From 1997-06-06 to 1997-06-30

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

Study performed to EU Method with no significant deviations.

Qualifier:

according to guideline

Guideline:

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

Deviations:

no

GLP compliance:

yes

Specific details on test material used for the study:

Batch No.: 9705-1A
Purity: >97%

Key result

Test procedure:

step 4

Remarks on result:

only step 4 of test procedure conducted because substance does not react violently with water

Remarks:

Evolution of gases was not observed.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item is not classified as a substance which, in contact with water, emit flammable gases.

Executive summary:

The test item was determined according to EU Method A.12 (Flammability (Contact with Water)).

Since it was known from handling the test material during this study that the test item does not react violently with water, tests 1 to 3 were considered unnecessary. The test was conducted in duplicate in an incubator at 20 °C. The gas collection was checked hourly for up to seven hours.

Evolution of gases was not observed.

 

The test item is not classified as a substance which, in contact with water, emit flammable gases.

Reference 4

Endpoint:

flammable liquids: obsolete as covered by section 'Flash point'

Data waiving:

study technically not feasible

Justification for data waiving:

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

Description of key information

Flammable solids:

The study does not to be conducted because the substance is a liquid.

Flammable liquids:

No flash point was determined for the substance, as the vapour of the test item was observed to ignite on boiling (80 °C).

Pyrophoric liquids:

The test item is non-pyrophoric.

Substances / mixtures which in contact with water emit flammable gases:

The test item is not classified as a substance which, in contact with water, emit flammable gases.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Flammable liquids: EC A9, No flash point was determined for the test substance, as the vapours of the test substance were observed to ignite on boiling (80 °C).

In accordance with Regulation (EC) No. 1272/2008 section 2.6.1, the substance should be classified as flammable liquid when a liquid has a flash point of not more than 60 °C. Therefore this substance should not be classified as flammable liquid.

 

Pyrophoric liquids: EC A13, the test item did not spontaneously ignite within five minutes or produce charring of the filter paper in any of the replicate tests.

In accordance with Regulation (EC) No. 1272/2008, table 2.9.1, a pyrophoric liquid shall be classified when the liquid ignites within 5 min when added to an inert carrier and exposed to air, or it ignites or chars a filter paper on contact with air within 5 min. Therefore, this substance should not be classified as pyrophoric liquids.

 

Substances and mixtures which in contact with water emit flammable gases: EC A12, evolution of gases was not observed.

In accordance with Regulation (EC) No. 1272/2008 section 2.12.2.2, a substance or mixture shall be classified as a substance or mixture which in contact with water emits flammable gases if spontaneous ignition takes place in any step of the test procedure. Therefore, the substance is not classified as a substance which in contact with water emits flammable gases.
