Applicant's summary and conclusion

Conclusions:

Doré was heated up to 400°C. There were no signs of self-ignition or self-heating over the duration of the test.

Executive summary:

Doré was heated up to 400°C and there were no signs of self-ignition or self-heating over the duration of the test. The results are taken from a GLP compliant study (Harlan 2010) following a modified method compatible with Method N.4 of the UN Transport of Dengerous Goods, Manual of Tests and Criteria. The study is considered to be reliable and acceptable for use for this endpoint.
