flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:

yes
Specific details on test material used for the study:
Batch number: CN61204501
Content: 95.5%
Physical condition: white powder
Expiration date: 2017-12-04
Storage: Room temperature
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
other: not readily combustible
Interpretation of results:
not classified based on GHS criteria
Conclusions:
Vulkacit P Extra N is not a readily combustible substance.
Executive summary:

The test was performed as stipulated in UN-MTC procedure Test N.1 'Test method for readily combustible solids') and in EC A.10, Guideline EC 440/2008.

A preliminary screening test was performed to determine if propagation by burning with flame or smoldering occurs without wetted zone. The substance was formed into a powder train about 250 mm long by about 20 mm wide by about 10 mm high on a non-combustible, nonporous and low heat-conducting base plate. If propagation over 200 mm of the train occurs within a specified time then the full test program to determine the burning rate is carried out.

The test item Vulkacit P Extra N melted on approach of the burner flame. The test item burned for about 1 s after removal of the burner flame and extinguished than. There was no burning up of the powder

train. The performance of the full test was not necessary.

Vulkacit P Extra N is not a readily combustible substance.
