Hello,
My Quality Engineers have a disagreement with the interpretation of switching rules under Z1.4. I queried the forum and couldn't find anything. Z1.4 isn't clear to me.
Engineer 1 says you define your inspection characteristic with an AQL and an Inspection Level (Level II, for example). If you were to switch from normal to tightened, you'd pick the same sample size code letter (i.e., the one for Level II), but you'd look up the sample size, acceptance number, and rejection number in the tightened table.
Engineer 2 says you define your inspection characteristic with an AQL. If you were to switch from normal to tightened, you'd pick the sample size code letter for Level III instead and look up the sample size, acceptance number, and rejection number in the tightened table.
Who is correct?
Engineer 2 is basically saying Level 1 = reduced, Level II = normal, and Level III = tightened. Engineer 1 says the Levels and the switching rule "state" are separate parameters.
