At the beginning of the 1960s, electronics component makers experienced difficulties as a result of the increased variety of products, since this hampered the progress of mass-production and cost reductions. The Electronic Industries Association of Japan (EIAJ) tried to solve this problem by making group standards (Component Engineering Standards: CES) which were suited to the markets of the day. In the process of making the draft standards, not only components makers but also television and radio set-makers joined the working groups and delivered their opinions. The working groups avoided setting strict standards so that members would not hesitate to use them. By the end of the 1960s, more than 80 CES had been established. Many set-makers used the CES standards to reduce the variety of components they purchased and this enabled the components makers to increase the level of mass-production. JIS standards were only applied to the establishment of technical terms, to definitions and to methods of testing. A negative point, however, was that as the tolerance of CES was assumed to be at a level similar to JIS, CES standards could not serve as a target for components makers who had already attained manufacturing techniques superior to JIS. These firms therefore gave priority to in-house specifications rather than to CES when producing parts for which new techniques were required.
