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 wheter 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 essay, it was observed that the propagation time for combustion over a strip of 200 mm of the test item was superior to 240 s. No further testing was required.
SEPISOL FAST RED SN is not considered as highly flammable.

Executive summary:

A test to determine if Sepisol Fast Red SN is a flammable solid has been carried out by following the EU method A.10.

The test material is formed into an mould powder train of 250 mm length, 20 mm width and 10 mm height on a low heat-conducting base plate. The powder train was ignited at one end with a micro burner (minimum diameter 5mm) for 2 minutes.

A preliminary essay was performed to determine the time for the combustion to propagate over a distance of 200 mm within 4 mintues. 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 Red SN is not a highly flammable solid according to the CLP regulation.
