Abstract
In this paper rules are discussed for suspending inspection on the basis of unfavorable lot history, when small sample sampling plans are specified. The decision to suspend, which is based on cumulative lot dispositions over k consecutive lots, occurs if j lots are rejected. The expected time to suspension is given for j = 2 and j = 3. The user is offered the choice of employing a designed plan of suspension systems based on MIL-STD-105D or designing a specific system using the notion of a reference quality level. Several methods of choosing a suspension system are discussed.
