Dear Marc,
I am working as quality system engineer at SMT & COB assembly company. I need your advice about the sampling plan.
Regarding QS9000 manual third edition,
Inspection and Testing - Element 4.10.
Acceptance Criteria for Attribute Characteristics - 4.10.1.1
Acceptance criteria for attribute data sampling plans shall be zero defect. Appropriate acceptance criteria for all other situations (eg. visual standards) shall be documented by the supplier and approved by the customer.
I'd like to settle the sampling plan with my customer. Pls. advise what is the correct method to find out sampling plan for zero defect between a) or b).
Example : Lot size 21,000 pcs. with 0.10% AQL, level II.
a) Refer to C=0 sampling plan table (as attached "C=0 sampling.jpg") from Nicholas L. Squelia, 4th edition : Zero Acceptance Number Sampling Plans, the sampling size is 294 pcs. The lot is rejected if found any defect.
b) Refer to single sampling plan table (as attached "ANSI ASQC Z1.4-1993 table 2a.jpg") from ANSI ASQC Z1.4-1993, the sampling size is 500 pcs. with defect allowance 1/2 (acc,/rej.). But according to mentioned QS9000, adapt it to sampling size 500 pcs. with defect allowance 0/1 (acc./rej.).
Pls. advise.
Thank you and Best regards,
Sarunya P.
