Research on the correction of smoldering rate of cigarette paper under non-standard atmospheric pressure
In order to modify the systematic difference between the smoldering rate of cigarette paper under non-standard atmospheric pressure and standard atmospheric pressure,four experimental samples were selected for smoldering rate in six laboratories with different atmospheric pressure (five non-standard atmospheric pressure laboratories and one approximate standard atmospheric pressure laboratory). According to the test results,the correlation was analyzed between atmospheric pressure and the smoldering rate. The correction equation was established for smoldering rate to non-standard atmospheric pressure,and the feasibility was verified. The results showed that:1) The smoldering rate of cigarette paper was positively correlated to atmospheric pressure,R2 ranged from 0.8572 to 0.9141,and the correlations between the smoldering rate in the four samples and atmospheric pressure all reached extremely significant level. 2) The correlation equation between the smoldering rate of cigarette paper to atmospheric pressure was rc=rm×(0.8157×√P0/P1+0.1936);3) The correction values of the experimental sample under non-standard atmospheric pressure was not significantly different from the smoldering rate at standard atmospheric pressure,and the maximum absolute deviation between the corrected value of the verified sample and the smoldering rate of the sample at standard atmospheric pressure was only 0.170. It showed that the correction equation could be used to correct the smoldering rate of cigarette paper under non-standard atmospheric pressure and eliminate the systematic difference between non-standard atmospheric pressure and standard atmospheric pressure.
