ANSI/ASQ Z1.4

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,
