If you're using a Type 5000 Pressure Balance with software to solve the pressure equation, the value to use for piston assembly density is 7920 kg/m3. Some calibration certificates show the reference but not the value, "The mass of the piston and plate assembly is adjusted so that under standard conditions the as left apparent mass of the assembly is equal to the apparent mass of a 0.2 kg AISI 304L stainless steel laboratory reference mass ±0.001%."
