Link to relevant study record(s)

Reference

Reference 1

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Type of information:

experimental study

Adequacy of study:

weight of evidence

Study period:

until 1988-06-22

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study without detailed documentation

Remarks:

only summary and parts of the in general well-documented study report available

Qualifier:

according to guideline

Guideline:

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

Deviations:

not specified

GLP compliance:

not specified

Key result

Test procedure:

other: not stated, but test was properly performed

Remarks on result:

no reaction with water observed

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Only summary and parts of the in general well-documented study report available, but given data indicate that the study was performed properly and the results are reliable.

Executive summary:

The rate of evolution and flammability of any gaseous products produced by action of water on the test item has been investigated.

The test conducted gives no indication of hazardous properties.

The test item, when in contact with water, does not produce gases that spontaneously ignite. In steps 1-3 of the test, no gas evolution or ignition was observed.

In step the maximum rate of gas evolution observed was 278 ml/kg per hour, which is well below the rate of 1 l/kg per hour which is considered hazardous.

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:

self-heating substances / mixtures

Type of information:

experimental study

Adequacy of study:

key study

Study period:

until 1986-11-14

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study

Reason / purpose for cross-reference:

reference to same study

Qualifier:

equivalent or similar to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.4 (Test method for self-heating substances)

Version / remarks:

According to the negative Grever oven test, the UN Manual of Tests and Criteria: Test No.4 is unnecessary.

Deviations:

not specified

GLP compliance:

not specified

Key result

Test procedure:

other: Grewer Oven test

Result:

negative outcome (no effect observed)

During this test no exothermic reaction was observed. However, the material did show two small endotherms centred at 76 °C and 136 °C. No further reaction occurred

Interpretation of results:

not classified based on GHS criteria

Conclusions:

No exotherm reaction was seen in the Grewer oven test, showing that the substance is not self-heating. The UN Manual of Tests and Criteria: Test No.4 is unnecessary.

Executive summary:

No exotherm reaction was seen in the Grewer oven test, showing that the substance is not self-heating. The UN Manual of Tests and Criteria: Test No.4 is unnecessary.

Reference 4

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

weight of evidence

Study period:

until 1986-11-14

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

comparable to guideline study

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

not applicable

GLP compliance:

not specified

Key result

Test procedure:

burning rate test over 100 mm length

Remarks on result:

other: No combustion occurred. In an area up to approximately 1 cm from the wire the test material melted. The test item is therefore classed as BZ 1.

Interpretation of results:

GHS criteria not met

Conclusions:

Test procedure wa sufficiently documented and is hence considered reliable. During burning test, no combustion occurred. In an area up to approximately 1 cm from the wire the test material melted. The test item is therefore classed as BZ 1.

Executive summary:

Testing was performed similar to EU method A.10. The test item was not considered to be a flammable solid.

Description of key information

EU method A.12: The test conducted gives no indication of hazardous properties.

EU method A.10. The test item is not a flammable solid.

Key value for chemical safety assessment

Flammability:

not classified
