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.

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.
