Key result
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record. | Remarks: | Additional remarks: tert-butyl-4-methoxyphenol ignited when the flame of bunsen burner having temperature of 950°C was brought in contact with it.
Test procedure:

Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record. | Remarks: | Additional remarks: tert-butyl-4-methoxyphenol ignited when the flame of bunsen burner having temperature of 950°C was brought in contact with it.
Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
Test chemical 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 test chemical is flammable only at high temperature of about 950°C. However since such high temperatures are not found under normal circumstances of transportation and use, test chemical was considered non-flammable.
Executive summary:

Test chemical 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 test chemical is flammable only at high temperature of about 950°C. However since such high temperatures are not found under normal circumstances of transportation and use, test chemical was considered non-flammable.

Description of key information

Test chemical 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 test chemical is flammable only at high temperature of about 950°C. However since such high temperatures are not found under normal circumstances of transportation and use, test chemical was considered non-flammable.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Test chemical 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 test chemical is flammable only at high temperature of about 950°C. However since such high temperatures are not found under normal circumstances of transportation and use, test chemical was considered non-flammable.

Justification for classification or non-classification

Test chemical 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 test chemical is flammable only at high temperature of about 950°C. However since such high temperatures are not found under normal circumstances of transportation and use, test chemical was considered non-flammable.
