Abstract To measure the effective area and discrimination threshold of a 1.2~10kPa pneumatic piston gauge,the FPG8601-type piston gauge (FPG) was used as the standard.The characteristics and traceability methods of the FPG8601-type piston gauge are introduced.The necessity of full-range measurement of pneumatic piston gauge and measurement procedure are expounded.The measurements were carried out at five different pressure including the lower limit of pneumatic piston gauge,and the average effective area of the piston-cylinder is 9.77371cm² .By changing different small weights on the piston of pneumatic piston gauge and reading the corresponding pressure value of the FPG8601-type piston gauge,the discrimination threshold of pneumatic piston gauge was measured.The discrimination threshold is better than 5mg which is better than 2×10^-5 compared with the measurement point.The uncertainty of the effective area at each point was evaluated,and the results show that the relative expanded uncertainty does not exceed 9.4×10^-5.

Key words： metrology pneumatic piston gauge effective area discrimination threshold
