Hi,
For critical defects where acc/ rej criteria is [0,1], what should my sample size be when using ANSI Z1.4?
For eg: Lot size = 151 to 280, general inspection II, therefore the code letter would be G.
Can I go to the double sampling plans for normal inspection, and just take the 1st sample size of the double sampling plan as my sampling plan.
i.e. sample size = 20; acc/ rej = [0,1]
Or I should go to single sampling plan instead?
i.e. sampling size = 32; acc/ rej = [0,1]
Please advise.
