CNQ 200 USING SAMPLE SYSTEMS. - QUALITY - D.A.U. UNIVERSITY

In the MIL-STD-1916 sampling system given the tightened sampling plan: sample size (n)=320, Ac=0, and Re=1, what is the acceptance decision if eight defects are found during inspection?

1. Accept because the defective products will be replaced before delivery.

2. Reject because eight defects are greater than or equal to the rejection number 1.

3.Accept because the percent nonconforming is less than or equal to the acceptance number.

4.Reject because percent nonconforming is greater than or equal to the rejection number.

Determine the verification level (VL). Use contract, QALI, or LOD criteria for determining the VL for each characteristic to be inspected. If a VL is not specified, use the MIL-HDBK-1916 criteria presented in this table. Default Verification Verification Level Range Level Critical VII VII Major | III to VIL IV Critical characteristics should always use VL VII. Minor I to III II Major characteristics should typically use VL levels between III and VI. If no VL is specified, then VL IV should be used. Minor characteristics should typically use VL levels between I and III. If no VL is specified, then VL II should be used for minors. The more important the characteristic is, the higher the VL. Lower VLs may also be considered where relatively small sample sizes are necessary and large sampling risks can or must be tolerated as, for example, when inspection costs are high.
