1. ZERO ACCEPTANCE NUMBER SAMPLING PLANS fourth edition by Nicholas L. Squeglia. This book gives a number of zero based sampling plans and their corresponding Operating Characteristic (OC) Curves and Values. It is the state of the art in zero based sampling plans. It's only draw back is as with all zero based sampling plans, the OC curves flatten out at the bottom. This means when the probability of you accepting a bad lot goes down to approximately 10% or below, you would be more apt to accept a bad lot using a zero based sampling plan. This document is made available by ASQC, Quality Press, 611 East Wisconsin Avenue, Milwaukee, Wisconsin 53202.
2. MIL-STD-1916, DoD PREFERRED SAMPLING PLANS FOR ACCEPTANCE OF PRODUCT This document contains a set of statistically sound sampling plans and procedures for planning and conducting the inspection of product to assess quality and provide information of conformance to contract requirements. This new military standard complies with the Department of Defense policy of eliminating acceptable quality levels (AQLs) and associated practices. The standard is currently available, however, the handbook addressing this standard and providing clarification is still being written. Also, some of these plan may be too stringent to use, based on contract requirements.
3. Electronic Industries Association (EIA) Standard, ZERO ACCEPTANCE NUMBER SAMPLING PROCEDURES AND TABLES FOR INSPECTION BY ATTRIBUTES BY A CONTINUOUS MANUFACTURING PROCESS Since conventional attribute sampling plans based on nonzero acceptance are no longer desirable, this industry standard places an emphasis on zero based sampling plans as they relate to Lot Tolerance Percent Defective (LTPD) value or the limiting quality protection of MIL-STD-105. The OC curves of this document are for the most part equal to or better than their associated MIL-STD-105 curves. Published by Electronic Industries Association, Engineering Department, 2001 Pennsylvania Ave. N.W., Washington, D.C. 20006. EIA Standard Sales Dept (202/457-4966).
You may wish to note if you still have contracts which require MIL-STD-105, American Society for Quality Control, now has available, ASQC Z1.4. a virtual exact copy of MIL-STD-105E.
Remember also, that in order to use the Contractor's sampling plan, the plan shall afford us equal or better protection that the requirements of the contract.
