Results and discussion

Pyrophoric solids
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record.
Pyrophoric liquids
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record.

Any other information on results incl. tables

Flammability Solids:

Results:

(i) Preliminary Test: On application of the test flame the test substance failed to ignite. It did not propagate combustion along the train and the burning time over 200mm could not be recorded.

(ii) Test Series: Not required.

Flammability contact with water:

Results:

Step 1: No gas evolved.

Step 2: No gas evolved.

Step 3: No gas evolved.

Step 4: Sample preparation: Sieved to S0.5mm particle size.

Room Temperature: 21 - 22°C

Water Temperature: 21 - 22°C.

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

PYROPHORIC PROPERTIES OF SOLIDS AND LIQUIDS:

Results:

Room temperature = 21°C

  N= No signs of ignition during dropping or throughout the 5 minute observation period.
 Test Number:  1.  2.  3.  4.  5.  6.
