1391 parts is the batch size. As per EN3004, table 4, discontinuities are considered as major defect with AQL = 0,065%. So, sampling shall be 200 parts instead of 125. The down arrow in table 4 is applicable for Acceptance/Rejection criteria and related sampling as well.
It should be good to add sampling for marking, surface treatment, dimensional and visual controls.
What is the sampling size for hardness test ?
