In the current situation, it is necessary to summarize the development history of China's standardization work. This paper reviews the formation of China's standardization concept and explores the relationship between standardization work and the shifts in the global situation.展开更多

Over the years,comparing with our national solar radiation standard(absolute cavity radiometer),its performance is very stable. As a working standard pyranometer,it has been used for more than twenty years in the field of metrological calibration of meteorological radiation instruments.展开更多

A set-up composed of an integrating sphere, a standard photometer and a group of five luminous flux standard lamps ranged from 25 to 200 W calibrated and traceable to the National Physical Laboratory （NPL, UK） is used to measure and recalibrate the total luminous flux for these five working standard lamps. After recalibration, NIS （Egypt） maintains the national scales for luminous flux in lumen.展开更多

Thus, it is necessary to develop ways to f＇md standardized work that is suitable for smaller enterprises. Therefore, we investigated two kinds of factories that utilized flexible manufacturing procedures for the ＂production of many models in small quantities,＂ and considered their work instructions, work contents, changeover methods, workers＇ abilities, etc. One of the compared processes was a case where there was defined standardized work, which was not observed. In the other, a QA （quality assurance） network was created to guarantee the quality. Based on the investigation results, we formulated improvement plans, had the supervisors review them, and clarified the characteristics of their problems. The results revealed areas where much attention was required to find standardized work for such processes. In addition, we made it possible to support the specification of difficult tasks and the renewal of standardized work by extending a standardized work table for the entry of workers＇ actions. This paper reports a method to define and make good use of standardized work tables and standardized work combination tables, i.e., a way to find and use standardized work based on the results of the previously mentioned factory investigation.展开更多
