equal to 0; and the number of minor defects is less than or equal to 4;
First-class products: the number of severe defects is equal to 0; the number of serious defects
is equal to 0; the number of minor defects is less than or equal to 7. Or the number of severe
defects is equal to 0; the number of serious defects is equal to 1; and the number of minor
defects is less than or equal to 3;
Qualified products: the number of severe defects is equal to 0; the number of serious defects is
equal to 0; the number of minor defects is less than or equal to 8. Or the number of severe
defects is equal to 0; the number of serious defects is equal to 1; and the number of minor
defects is less than or equal to 6.
Batch (sample)
Superior product batch: the number of superior products in the appearance sample is greater
than or equal to 90%; and the number of first-class products and qualified products is less than
or equal to 10% (excluding unqualified products).
First-class product batch: the number of products above first-class products in the appearance
sample is greater than or equal to 90%; and the number of qualified products is less than or
equal to 10% (excluding unqualified products).
Qualified product batch: the number of products above qualified products in the appearance
sample is greater than or equal to 90%; and the number of unqualified products is less than or
equal to 10% (excluding unqualified products with severe defects).
