Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- 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 a solid which decomposes before boiling
