Key result
Test procedure:
other: not specified
Remarks on result:
other: 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione 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:
3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione 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 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione was considered non-flammable.
Executive summary:

3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione 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 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione was considered non-flammable.

Description of key information

3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione 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 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione was considered non-flammable.

Additional information

3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione 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 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione was considered non-flammable.

Justification for classification or non-classification

3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione 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 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione was considered non-flammable.
