Attribute sampling plans are used to inspect incoming, in-process, and final products to determine compliance with established acceptance criteria.
ANSI/ASQ Z1.4 sampling tables provide a quicker way of selecting a sampling plan without the use of complex statistics.
Until now, selecting the correct sampling plan required the user to look up a complex series of tables. This approach is error-prone.
This app provides the appropriate sample size and the accept and reject criteria based on
i. lot size (8 to 500,000+),
ii. AQL level (0.01 to 100),
iii. Inspection levels (3 normal + 4 special), under
iv. Normal, Reduced, and Tightened Inspection
