As a result of globalization process and TBT agreement, KS is also being revised, reestablished and some are abolished according to international standards such as ISO, IEC, etc. Conventional KS sampling inspection standards contained many different procedures from ISO, but recently, to match with international standards, all the rest of the standards except KS A 3102, 3104, 3151 were abolished, and the even the ones being in use still are also scheduled and be revised. Especially, KS A 3101, KS A 3105, KS A 3109, which were used most frequently in Korea were abolished, and the KS A ISO $2859-0\~3$ which coincide with ISO standards were established 3 years ago, but the implementation rate is very slow. Starting next year the national examination for qualification process for the product quality related item will the started and the preparation is underway. This study will investigate the recent sampling inspection process of KS as well as SPC related KS overhaul problem and present the data to help workers in SPC related field. One of the main example will be on KS A ISO 2859-3 and will attempt to help those medium and small sized companies with examples.

The growing importance of product quality is becoming more and more daily apparent as we enter the age of globalization around the world. And the product safety is getting more focus as well as product quality. As a result, many domestic companies are putting a lot of emphasis on safety measures and management activities and these companies' products are mainly superior to other companies' product. When we separate the product quality procedure into 3 steps, i.e. quality secure-quality confirm-quality guarantee, of course the 1st step is the most important, but also End step of product quality confirm process is important. And in mass production environment, sampling inspection is more desirable than the 100 % inspection procedure. As a part of globalization trend, KS system is also being revised and reestablished based on ISO, IEC, etc. which are based on international standard. Conventional KS sampling inspection standards were in many areas quite different from ISO sampling standards, only KS A 3102, 3104, 3151 are left and the rest become obsolete, and even the ones that are still around are planned to the gone step by step. It has been already 3 years since the new KS A ISO 2859-0-3 sampling inspection process has been established which the abolition of the popular KS A 3101, KS A 3105, KS A 3109, yet the implementation rate is very slow. This study will attempt to analyze the new KS A ISO 2859-2 and KS A ISO 2859-3, and try to understand the difference as that the new standard can be easily understood and used widely among companies, by using examples. Our attempt is to help implement with the companies with active safety involvement but the final result can be spread among other companies as well in the near future.

This paper is concerned with the International Standard ISO 2859-1 (1989), Sampling Plans Indexed by Acceptable Quality Level (AQL) for Lot-by-Lot Inspection, his standard is AQL type sampling scheme, and incorporates switching rules to move among normal, tightened, and reduced inspections. Sample size code letters and inspection levels of ISO 2859-1 are the same as those of other attributes standards MIL-STD-105D, ANSI Z1.4, and KS A 3109. But ISO 2859-1 has more simple switching rules than KS A 3109 has. The sampling procedures of the ISO 2859-1 are matched to the variables international standard ISO 3951 to enable us to move between them. Composite OC and ASN curves are given for AQL 2.5% and code letter F.
