Key result
Remarks on result:
other: 2,2'-[(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-nonylphenol] ignites only when flame of bunsen burner having temp of 950°C is brought in contact with it.Thus it concluded that substance is flammable only at high temp of about 950°C.
Conclusions:
2,2'-[(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-nonylphenol] (CAS no. 67990-27-6) did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 2,2'-[(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-nonylphenol] (CAS no. 67990-27-6) is not auto-flammable.
Executive summary:

2,2'-[(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-nonylphenol] (CAS no. 67990-27-6) did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 2,2'-[(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-nonylphenol] (CAS no. 67990-27-6) is not auto-flammable.
