Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with national standard methods

Remarks:

according to Directive VDI 2263, part I

Reason / purpose for cross-reference:

reference to same study

Qualifier:

according to guideline

Guideline:

other: Directive VDI 2263, part I

Test procedure:

burning rate test: preliminary screening test

Burning time:

425 s

Test procedure:

other: VDI 2263, part 1

Remarks on result:

other: combustion class BZ 5

Remarks:

bruning with flame or spark generation

Using an ignition source (flame or hot wire, 2 min) at ambient temperature spreading of combustion wasobserved. .

The combustion behaviour of the product at ambient and at elevated temperature is characterized by the burning index BZ 5 (burning with flame of spark generation) and the burning rate had to be determined.

In the preliminary test the burning rate of 425 s/200 mm clearly exceeded the limit of 120 s. Therefore no main test had to be conducted

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The substance has not to be classified as flammable solid according to Regulation (EC) no 1272/2008

Key value for chemical safety assessment

Flammability:

not classified
