Sampling Plans
Our Statistical Sampling Plans are based on ASQC Z1.4 2008 Level II with Zero rejects. Sampling may vary by the manufacturing process. Please refer to Table 1 and Table 2 below for examples of sampling plans for our Non-Additive and Additive processes. Please refer to our Inspections and Sampling Plans page for more information on which processes we provide inspection and statistical sampling.
