Rationale for reliability incl. deficiencies:

other: Basic data given

Principles of method if other than guideline:

Flammability test of solid substances according to company guideline
Determination of burning number and burning time.

Test procedure:

burning time (test type not further specified)

Remarks:

or specified in description of method (migrated information)

Burning time:

ca. 175 s

Remarks on result:

other: Burning distance 100 mm

The test substance burns by itself after contact with an ignition source.

The combustion class BZ 5 (spread of an open fire) was assigned.

Interpretation of results:

non flammable

Remarks:

Migrated information

Conclusions:

The test substance showed spread of an open fire (BZ 5) with a burning time of 175 s for a burning distance of 100 mm. Classification as a flammable solid class 4.1 is not required.

Executive summary:

The flammability of the test substance was determined by a combustion class (BZ) test. The test substance showed spread of an open fire (BZ 5) with a burning rate of 0.57 mm/s. The test item is not a flammable solid.
