Reference
Endpoint:
flammability
Remarks:
Pyrophoric liquids/solids (migrated from section 'Flammability')
Type of information:
experimental study
Adequacy of study:
key study
Study period:
07.03.2013 to 18.03.2013
Reliability:
1 (reliable without restriction)
Qualifier:
according to guideline
Guideline:
other:
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:
no
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record. | Remarks: | Additional remarks: 6-amino-4-hydroxynaphthalene-2-sulphonic acid ignited when the flame of bunsen burner having temperature of 950 degC was brought in contact with it.
Test procedure:

Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record. | Remarks: | Additional remarks: 6-amino-4-hydroxynaphthalene-2-sulphonic acid ignited when the flame of bunsen burner having temperature of 950 degC was brought in contact with it.
Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
From the experimental values of flammability, 6-amino-4-hydroxynaphthalene-2-sulphonic acid ignited when the flame of bunsen burner having temperature of 950 degC was brought in contact with it. Thus it can be concluded that 6-amino-4-hydroxynaphthalene-2-sulphonic acid is flammable only at high temperature of about 950 degC. However since such high temperatures are not found under normal circumstances of transportation and use, 6-amino-4-hydroxynaphthalene-2-sulphonic acid was considered non-flammable for chemical safety assessment.
Executive summary:

From the experimental values of flammability, 6-amino-4-hydroxynaphthalene-2-sulphonic acid ignited when the flame of bunsen burner having temperature of 950 degC was brought in contact with it. Thus it can be concluded that 6-amino-4-hydroxynaphthalene-2-sulphonic acid is flammable only at high temperature of about 950 degC. However since such high temperatures are not found under normal circumstances of transportation and use, 6-amino-4-hydroxynaphthalene-2-sulphonic acid was considered non-flammable for chemical safety assessment.

Description of key information

From the experimental values of flammability, 6-amino-4-hydroxynaphthalene-2-sulphonic acid ignited when the flame of bunsen burner having temperature of 950 degC was brought in contact with it. Thus it can be concluded that 6-amino-4-hydroxynaphthalene-2-sulphonic acid is flammable only at high temperature of about 950 degC. However since such high temperatures are not found under normal circumstances of transportation and use, 6-amino-4-hydroxynaphthalene-2-sulphonic acid was considered non-flammable.

Flammability:
not classified

Additional information

From the experimental values of flammability, 6-amino-4-hydroxynaphthalene-2-sulphonic acid ignited when the flame of bunsen burner having temperature of 950 degC was brought in contact with it. Thus it can be concluded that 6-amino-4-hydroxynaphthalene-2-sulphonic acid is flammable only at high temperature of about 950 degC. However since such high temperatures are not found under normal circumstances of transportation and use, 6-amino-4-hydroxynaphthalene-2-sulphonic acid was considered non-flammable.

Justification for classification or non-classification

From the experimental values of flammability, 6-amino-4-hydroxynaphthalene-2-sulphonic acid ignited when the flame of bunsen burner having temperature of 950 degC was brought in contact with it. Thus it can be concluded that 6-amino-4-hydroxynaphthalene-2-sulphonic acid is flammable only at high temperature of about 950 degC. However since such high temperatures are not found under normal circumstances of transportation and use, 6-amino-4-hydroxynaphthalene-2-sulphonic acid was considered non-flammable.
