Event Description

Description :

ANSI/ASQ Z1.9 (formerly MIL-STD 105) is an internationally recognized set of sampling plans for attribute (pass/fail, good/bad, or defect count) data. The standard specifies, on the basis of (1) the lot size N, (2) the inspection level, and (3) the acceptable quality level (AQL), a sample size n and acceptance number c. If the number of nonconformances exceeds the acceptance number, the lot is rejected. This does not mean the entire lot is thrown away, but rather that 100% inspection is required to remove all nonconforming items and possibly replacing them with known good ones.

Objective :

Use ANSI/ASQ Z1.9 to define a sampling plan on the basis of (1) the lot size N, (2) the inspection level, and (3) the acceptable quality level (AQL).
- Be aware of the "chutes and ladders" (up and down arrows) aspect of the sampling tables.
Know how double and multiple sampling plans reduce the amount of inspection and therefore inspection costs
Generate a sequential sampling plan whose performance is identical to that of the corresponding ANSI/ASQ Z1.9 plan at the operating characteristic curve points (AQL, 1-a) and (RQL, b).
- This can be done in Microsoft Excel, and attendees will be provided with a spreadsheet, or an off-the-shelf program like StatGraphics.

Areas Covered in the Session :

Comprehensive overview of ANSI/ASQ Z1.9 including
Generation of a sequential sampling plan whose performance (operating characteristic curve) is essentially identical to that of the corresponding ANSI/ASQ Z1.9 plan

Who Will Benefit:

ALL Quality managers, engineers, and technicians with responsibility for lot inspections that use attribute data.
