Administrative data

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: see 'Remark'

Remarks:

The reliability is rated 2 because the study followed the standard guideline of reference (EU A.10 method), which describes a procedure designed to evaluate this endpoint. The results were reviewed for reliability and assessed as valid. Nevertheless no information was available whether or not the study was conducted under GLP condition.

Applicant's summary and conclusion

Interpretation of results:

non flammable

Remarks:

Migrated information

Conclusions:

In a preliminary assay,it was observed that the propagation time for combustion over 200 mm was superior to 240 s. No further testing was required.
SEPISOL FAST VIOLET 881239 is not considered as highly flammable.

Executive summary:

The determination of the flammability of Sepisol Fast Violet 881239 has been carried out following the EU method A.10.

The test material is formed into an mould powder train of 250 mm length and 10 mm height on a low heat-conducting base plate. The powder train was ignited at one end with a flame for 2 minutes maximum (Bunsen burner, minimum diameter 5mm).

A preliminary essay was performed to determinated the time for the combustion to propagate over a distance of 200 mm within 4 minutes. It was observed that the propagation time was superior to 240 s. So no further testing was required according to the guideline.

It has been concluded that Sepisol fast Violet 881239 is not a highly flammable solid according to the 67/548/CE directive and the CLP regulation.
