The National Institute for Standards (NIS), Egypt, has developed and constructed a new primary force standard, a 1kN deadweight machine (DWM) at its facility in Egypt. The new machine features low cost and compact size, making it an excellent option for manufacturing and smaller laboratories. In this paper, the 1kN DWM is introduced with explanation and description of the design criteria, construction features, and uncertainty evaluations. In addition, the paper demonstrates the advantages and disadvantages of this purely local attempt supported by suggested future work.
