Key result
Test procedure:
other: Not specified
Remarks on result:
other: 4-hydroxy-6-(methylamino)naphthalene-2-sulfonic acid not ignited when the flame of bunsen burner having temperature of approximately 950°C was brought in contact with it.
Interpretation of results:
other: non flammable
Conclusions:
4 -hydroxy-6 -(methylamino)naphthalene-2 -sulfonic acid does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that 4 -hydroxy-6 -(methylamino)naphthalene-2 -sulfonic acid is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 4 -hydroxy-6 -(methylamino)naphthalene-2 -sulfonic acid was considered non-flammable for chemical safety assessment.
Executive summary:

4 -hydroxy-6 -(methylamino)naphthalene-2 -sulfonic acid does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that 4 -hydroxy-6 -(methylamino)naphthalene-2 -sulfonic acid is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 4 -hydroxy-6 -(methylamino)naphthalene-2 -sulfonic acid was considered non-flammable for chemical safety assessment.
