*In standard ISO/IEC 15426-1 the values for defects and decodability are cited as absolute values
with reliable tolerances of +/-0.08. For improved comprehensibility, we refer to these two values on
the test reports as percentages. The corresponding tolerance values are therefore +/- 8. In the
event that the tolerances for decodability and/or defects are exceeded, the device must be
inspected and serviced at the manufacturer.
