Results and discussion
Pyrophoric solids
- 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: not flammable
Pyrophoric liquids
- 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)

- corresponding to 'no' in migrated source record. | Remarks: | Additional remarks: not flammable
Applicant's summary and conclusion
- Interpretation of results:
- non flammable
- Remarks:
- Migrated information
- Conclusions:
- It can be concluded that 3-amino-4-methoxybenzenesulphonic acid is flammable only at high temperature of about 950 deg C. However since such high temperatures are not found under normal circumstances of transportation and use, 3-amino-4-methoxybenzenesulphonic acid was considered non-flammable for chemical safety assessment.
- Executive summary:
From the experimental values of flammability, 3-amino-4-methoxybenzenesulphonic acid ignited when the flame of Bunsen burner having temperature of 950 deg C was brought in contact with it. Thus it can be concluded that 3-amino-4-methoxybenzenesulphonic acid is flammable only at high temperature of about 950 deg C. However since such high temperatures are not found under normal circumstances of transportation and use, 3-amino-4-methoxybenzenesulphonic acid was considered non-flammable for chemical safety assessment.
