- Endpoint:
- pyrophoric liquids
- Remarks:
- aqueous solution
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
- GLP compliance:
- no
- Endpoint:
- substances / mixtures which in contact with water emit flammable gases
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture
- Endpoint:
- flammable solids
- Data waiving:
- study technically not feasible
