Key result
Remarks on result:
other: 2-amino-5-hydroxynaphthalene-1,7-disulfonic acid 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 substance is flammable only at high temperature of about 950°C.
Conclusions:
2-amino-5-hydroxynaphthalene-1,7-disulfonic acid did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 2-amino-5-hydroxynaphthalene-1,7-disulfonic acid is not auto-flammable.
Executive summary:

2-amino-5-hydroxynaphthalene-1,7-disulfonic acid did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that  2-amino-5-hydroxynaphthalene-1,7-disulfonic acid is not auto-flammable.
