Certification of Reference Materials for Distillation of Kerosene

This paper studies the atmospheric distillation method based on the method in the national standard GB/T 6536-2010, with the focus on the traceability of the recovered temperature. The consistency between the measured recovered temperatures by a platinum resistance and by a mercury thermometer was achieved. We collaborated with several laboratories to certify the CRM developed. The uncertainty of the certified values U_c (k=2) from the initial boiling temperature to 95% of the recovered temperature ranged from 0.7 ℃ to 4.6 ℃.
