- Abstract:
- The 5 t standard weight was constructed to support the newly design of 1 MN deadweight force standard machine in Korea according to International Organization of Legal Metrology (OIML)’s requirements. The weight consists of five pieces of 1 t weight and was considered safety and convenience in handling of large capacity. We have also set up a commercial mass comparator with auto-centering pan for calibration of up to 5 t deadweights. Each 1 t piece was compared with 1 t mass standard by the method of double substitution. We have tested the repeatability of comparator with the newly manufactured 5 t weight. In this presentation, however, we summarize the manufacturing procedures of weight and the preliminary test result of comparator’s performance.
