Key result
Test procedure:
other: Not specified
Remarks on result:
other: disodium [μ-[[7,7'-iminobis[4-hydroxy-3-[[2-hydroxy-5-sulphamoylphenyl]azo]naphthalene-2-sulphonato]](6-)]]dicuprate(2-) 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:
Disodium [μ-[[7,7'-iminobis[4 -hydroxy-3 -[[2 -hydroxy-5 -sulphamoylphenyl]azo]naphthalene-2 -sulphonato]](6 -)]]dicuprate(2 -) 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 disodium [μ-[[7,7'-iminobis[4 -hydroxy-3 -[[2 -hydroxy-5 -sulphamoylphenyl]azo]naphthalene-2 -sulphonato]](6 -)]]dicuprate(2 -) is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus disodium [μ-[[7,7'-iminobis[4 -hydroxy-3 -[[2 -hydroxy-5 -sulphamoylphenyl]azo]naphthalene-2 -sulphonato]](6 -)]]dicuprate(2 -) was considered non-flammable for chemical safety assessment.
Executive summary:

Disodium [μ-[[7,7'-iminobis[4 -hydroxy-3 -[[2 -hydroxy-5 -sulphamoylphenyl]azo]naphthalene-2 -sulphonato]](6 -)]]dicuprate(2 -) 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 disodium [μ-[[7,7'-iminobis[4 -hydroxy-3 -[[2 -hydroxy-5 -sulphamoylphenyl]azo]naphthalene-2 -sulphonato]](6 -)]]dicuprate(2 -) is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus disodium [μ-[[7,7'-iminobis[4 -hydroxy-3 -[[2 -hydroxy-5 -sulphamoylphenyl]azo]naphthalene-2 -sulphonato]](6 -)]]dicuprate(2 -) was considered non-flammable for chemical safety assessment.
