Event Description

Description :

ANSI/ASQ Z1.9 (formerly MIL-STD 414) is a generally accepted sampling standard for products with real-number (variables) data. Acceptance or rejection depends on the sample statistics. The sampling plan itself is a function of the lot size, acceptable quality level (AQL), and sampling level. Switching rules similar to those for ANSI/ASQ Z1.4 (MIL-STD 105) determine whether sampling is at the normal, tightened, or reduced level.

Areas Covered in the Session :

Practical requirements for drawing the sample

Plan considerations: one-sided or two-sided specification? Equal or unequal AQLs for the two specification limits? Process variation known or unknown?
Selection of normal, tightened, or reduced inspection as a function of quality performance and consistency of production
Definition of the appropriate sample plan (sample size and acceptance criteria) on the basis of the lot size N, sampling level, and AQL
Calculation of sample statistics and quality indices, and estimation of the nonconforming fraction (at each specification limit if necessary) to determine whether the lot should be accepted

Who Will Benefit:

Manufacturing and quality engineers, technicians, and inspectors with responsibility for inspections that involve quantitative measurements of parts.
