Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Executive summary:

The work of this group pre-dates range finding toxicity guidelines and provided much of the basis for their development. Their results are cited by many subsequent authoritative review bodies and are often found in SIDS and SIAR documents via secondary references. Therefore, these results are deemed reliable.
