Abstract: Metrology performances has been compared for diverse force standard machines all over the world, and it has been expounded that research situation of Chinese force metrology standards and some advanced technologies.A new technology of loading weight respectively is suggested, which is effective for reducing load fluctuation caused by counter-span exchanging weihgts of deadweight force standard machines and for solving counter-force phenomenon. A system of build-up force standard machine is developed, its force transducers are acted as reference standards and its value can trace to primary force standards directly. All above are expected to offer a referrence for designing and developping a large scale force metrology standards.
