Conformity (compliance)
testing
The
program conform1e.exe
is freeware and can be downloaded in the usual way. The program is written in
Delphi 4Ò and requires
Windows 95Ò or later. A
monitor with a resolution of 800 ´ 640 is recommended.
The
file manual.doc
contains the manual for running the program.
The
file formulas.doc
contains information of the formulas used in the calculations.
The
program calculates the probability of declaring conformity for an entity with
specified requirements. The following four cases are covered by the program:
RPV
denotes Region of permissible values
while RNV denotes Region of
non-permissible values. The specification limits are denoted LV, LVL,
LVU, LV1 and LV2, respectively.
The
calculations are performed according to the guidelines given in ISO/DIS
10576-1; Draft International Standard. (1999). Statistical
methods — Guidelines for the evaluation of conformity with specified
requirements. Part 1: General principles. Genéva: International
Standardization Organization. This standard is expected to be published as a
Final Draft International Standard early in 2002. A theoretical exposition of
the concept conformity testing can be found in Holst E, Thyregod P, Wilrich P.
(2001): On conformity testing and the
use of two-stage procedures. Int. Statistical Review, Vol 69 (3).
