Executive summary:

The mean between both determinations of the test item N,N'-hexane-1,6-diylbis(hexahydro-2-oxo-1H-azepine-1-carboxamide) gives the following value for the melting range:

Melting range: 84.5 to 86.6 °C (357.7 to 359.8 K)

Standard deviation: 0.21 K (begin); 0.35 K (end)

Estimated accuracy: ± 0.3 K

All validity criteria were met.
