| Abstract: | The result of these comparison measurements have shown that it is possible to determine theoretically the effective transmission ratio of the hydraulic force standard machines with a relative uncertainty of about 1 à 10-4 for the mean widening of the piston cylinder systems. Furthermore, it is possible to apply the same stack of dead to the different, independent loading piston-cylinder systems for the different nominal forces and thus achieve an economical solution for the design of the hydraulic force standard machines. |
