Acceptable Quality Levels (AQL) - What is the usage of AQL 100 to 1000?

Hi,

ISO 2859-Sampling procedures for inspection by attributes

5.2 Specifying AQLs
The AQL to be used shall be designated in the contract or by (or in accordance with the prescription laid down by) the
responsible authority. Different AQLs may be designated for groups of nonconformities considered collectively or for
individual nonconformities as defined in 3.1.5. The classification into groups should be appropriate to the quality
requirements of the specific situation. An AQL for a group of nonconformities may be designated in addition to AQLs for
individual nonconformities, or subgroups, within that group. When the quality level is expressed as percent of
nonconforming items (3.1.8 and 3.1.9), AQL values shall not exceed 10 % nonconforming. When the quality level is
expressed as number of nonconformities per 100 items (3.1.10 and 3.1.11), AQL values up to 1 000 nonconformities
per 100 items may be used.

Starting to get Involved
Though this topic does't seem to have been picked up for a long time, and considering what has been elaborately explained here, I'm quiet confused by the way many, if not all of the quality inspection providers I have worked with so far misinterpret the AQL rules by mixing defects with defectives. I've never seen an inspection report differentiating defects and defectives either. Does this actually really exist and does anyone have a sample?
