| Abstract: | By the result of repeated tests on the lead of the ketchup, the paper calculated the standard deviation of the experiment, analyzed and calculated the value of the standard uncertainty that the systematic effect produces in the course of testing, and reached the rational evaluation of standard uncertainty of measurement on the lead of the ketchup, and expanded appropriately to combined standard uncertainty. |
