Pressure balance used as standard in the pressure range 0.1 to 1 Gpa

摘要

To complete his celibration facilities in the ranae 10 kPa to 200 MPa, L. N. E. has developed a new pressure balance in the range 30 - 1 000 MPa. This balance wzs especielly lecicned in order to determine the pressure distortion coefficients of the piston-cylinder essenblies. The uncerteinty of this standard was estimated to be #xB1; 20#xD7;10#x2212;6at 100 Mpa and #xB1;90#xD7;10#x2212;6at 1 000 MPa.
