ISO/IEC 15416 Verification Method
The grade of each scan is converted to a numeric value according to the table on the left.
The average is calculated from the grades of the data from 10 scans. Then, this average is further classified into a grade according to the total grade judgment table.
In the example shown in the table on the left, the average is 2.9.
|Average||ISO/IEC 15416 total grade|
|4.0 to 3.5||A|
|3.4 to 2.5||B|
|2.4 to 1.5||C|
|1.4 to 0.5||D|
|0.4 to 0.0||F|
The total grade is determined for the calculated average according to the table on the left.
