Abstract (English):
To determine the duration of pyrolysis of PVC building structures’ coke residue through elemental analysis, it is suggested to conduct complex laboratory studies in order to measure the correlation of the residual CHNS concentration (pyrolysis duration substances). The data obtained will help to determine the duration of temperature effect on certain polymeric materials. Meanwhile, the one is a list of major challenges in searching for the hearth of initial combustion in fire investigation.

Keywords:
elemental analyzer, coke residue, CHNS indicators, PVC, experimental research
