AnStat is an ANSI/ASQ z1.4 2003 ( z1.4-2008 ) and MIL-STD-105E standards sampling plans software program that takes the tedium and irritation out of extrapolating a sampling plan on Sampling Plan Charts, and eliminates the need for pricey slide rules that can break or become lost.

- Perform single, double, and multiple inspection plans, with normal (standard), reduced (loosened), or strict (tightened) inspection levels.

- Store and print log reports for inspections, and store profiles for frequently inspected items.

- Easily calculates sample numbers based on lot size.

- This inspection and quality control sampling plan
software tells accept and reject levels for all lots samples instantly.

- AQL - Acceptable Quality level - is easy to select at the touch of a button.

AnStat is essential for any and all quality control engineers, or anyone overseeing or supervising quality control or quality assurance

From there, all you have to do is select your AQL (Acceptable Quality Levels) and you are told immediately how many units to inspect and what the pass:fail ratio is.

A note about 2003 vs. 2008:

The ASQ (American Society for Quality) has released the ANSI/ASQ Z1.4-2008 standard. The foreword of this standard states:

"This standard is a reaffirmation of ANSI/ASQC Z1.4-2003, "Sampling Procedures and Tables for Inspection by Attributes."

There are no changes from the ANSI/ASQ Z1.4-2003 to ANSI/ASQ Z1.4-2008 standard. All ASQ Inspector's charts conforming to ANSI/ASQ Z1.4-2003 also conform to ANSI Z1.4-2008.

Differences: ANSI/ASQ Z1.4-2008 is nearly identical to MIL-STD-105E.

There are no changes in the tables of sampling plans. The only change in the switching rules is that ANSI/ASQ Z1.4-2008 makes the use of the limit numbers for switching to reduced optional. In addition, ANSI/ASQ Z1.4-2008 contains additional OC curves called scheme OC curves that describe the protection provided by the switching procedure during periods of constant quality. Numerous changes where also made to the explanatory text but which do not affect any procedures.

The MIL-STD-105E was officially cancelled in February 1995 by the Air Force to eliminate duplication. Many other standards were cancelled as well where equivalent civilian standards existed.
