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.

Any other information on results incl. tables

The pile failed to ignite during the 2 minutes that the Bunsen flame was applied. The result of the preliminary screening test obviated the need to perform the main test. The material is therefore not considered to be highly flammable.

The moisture content was determined gravimetrically.

  Determination A Determination B
a) Mass of loss bottle (g) 19.3537 20.6947
b) Mass of loss bottle and test material (g) 20.3989 21.6731
c) Mass of loss bottle and test material after drying (g) 20.3774 21.6529
Moisture content (% w/w) 2.057 2.065
Mean moisture content (% w/w)

2.06

The moisture content was calculated using the following equation:

Moisture Content (%) = (b - c) / (b - a) x 100

Applicant's summary and conclusion

Conclusions:
The test material has been determined to be not highly flammable as it failed to ignite in the preliminary screening test.
Executive summary:

In a determination of hazardous physico-chemical properties study (Harlan project number: 0959/0225) the test material has been determined to be not highly flammable as it failed to ignite in the preliminary screening test. The pile failed to ignite during the 2 minutes that the Bunsen flame was applied. The result of the preliminary screening test obviated the need to perform the main test.

The flammability (solids) was determined by measuring the burning rate of test material prepared as a pile of set dimensions. Testing was conducted using Method A10 Flammability (Solids) of Council Regulation (EC) No 440/2008 of 30 May 2008, Part A: Methods for the determination of physico-chemical properties.
