Burning time:
89 - 103 s
Key result
Test procedure:
ignition time on contact with air
Remarks on result:
no ignition on contact with air (not further specified)

Flammability: The burning times over 100 mm of the six measurements were 103, 90, 93, 89, 97 and 95 seconds. The shortest burning time was 89 seconds.

Flammability in contact with water: The practical experience of the sponsor and the test facility shows that no gases are developed, when the test substance is in contact with water.

Pyrophoric Properties: The test was not performed experimentally because practical experience exists at the sponsor and the test facility, e.g. when handling small amounts of the test substance repeatedly in air during testing for e.g. subacute toxicity. Also experience from the test for self-ignition of the test substance at elevated temperature is available. The test substance does not ignite in air at ca. 20 °C and the self-ignition temperature was greater than 170 °C (see Section 4.12).

Interpretation of results:
GHS criteria not met
Conclusions:
The burning times over 100 mm of the six measurements were 103, 90, 93, 89, 97 and 95 seconds. The shortest burning time was 89 seconds.
The test substance burned over a length of 200 mm within 4 minutes but did not burn over a length of 100 mm within 45 seconds in the main test.
The test substance is therefore not classified as "highly flammable", according to the guideline.
The test substance is regarded as not being flammable in contact with water.
The test substance is regarded as not being pyrophoric.
Executive summary:

The flammability, the pyrophoricity and the flammability in contact with water of the test substance "TAZOBACTAM ACID" was determined according to EC-methods.

The burning times of a test substance pile over 100 mm were between 89 and 103 seconds.

The practical experience shows that no gases are developed, when the test substance is in contact with water.

Practical experience exists also demonstrating that the test substance is not pyrophoric.

The test substance is therefore not classified as "highly flammable", according to the guideline.

The test substance is regarded as not being flammable in contact with water.

The test substance is regarded as not being pyrophoric.

Description of key information
