Reference
Endpoint:
flammability
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
comparable to guideline study
Justification for type of information:
Experimental test result performed using standard test guidelines
Reference:
Composition 0
Qualifier:
according to
Guideline:
other: It is how easily substance can burn or ignite, causing fire or combustion by brief contact with an ignition source (such as a burning match)
Principles of method if other than guideline:
It is how easily substance can burn or ignite, causing fire or combustion by brief contact with an ignition source (such as a burning match)
GLP compliance:
not specified
Test material information:
Composition 1
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
other: Tris[5-amino-4-hydroxy-3-(phenylazo)naphthalene-2,7- disulphonato(2-)]dialuminium ignited when the flame of bunsen burner having temperature of 950°C was brought in contact with it.
Interpretation of results:
other: non flammable
Conclusions:
Tris[5-amino-4-hydroxy-3-(phenylazo)naphthalene-2,7- disulphonato(2-)]dialuminium ignites only when the flame of bunsen burner having temperature of 950°C is brought in contact with it. Thus it can be concluded that Tris[5-amino-4-hydroxy-3-(phenylazo)naphthalene-2,7- disulphonato(2-)]dialuminium is flammable only at high temperature of about 950°C. However since such high temperatures are not found under normal circumstances of transportation and use, Tris[5-amino-4-hydroxy-3-(phenylazo)naphthalene-2,7- disulphonato(2-)]dialuminium was considered non-flammable for chemical safety assessment.
Executive summary:

Tris[5-amino-4-hydroxy-3-(phenylazo)naphthalene-2,7- disulphonato(2-)]dialuminium ignites only when the flame of bunsen burner having temperature of 950°C is brought in contact with it. Thus it can be concluded that Tris[5-amino-4-hydroxy-3-(phenylazo)naphthalene-2,7- disulphonato(2-)]dialuminium is flammable only at high temperature of about 950°C. However since such high temperatures are not found under normal circumstances of transportation and use, Tris[5-amino-4-hydroxy-3-(phenylazo)naphthalene-2,7- disulphonato(2-)]dialuminium was considered non-flammable for chemical safety assessment.

Description of key information

 Tris[5-amino-4-hydroxy-3-(phenylazo)naphthalene-2,7- disulphonato(2-)]dialuminium ignites only when the flame of bunsen burner having temperature of 950°C is brought in contact with it.
