Note: The actual quality of steel bars and the nominal quality deviation are calculated as follows
Mass deviation (%) = ã€{The actual total mass of the sample - (The total length of the sample * nominal mass)} / The total length of the sample * Nominal mass] * 100
Among them: the total number of samples is not less than 10, the total length of not less than 60m.
