Key Comparison of National Pressure Standards in the Range 1 Pa to 15 kPa of Absolute and Gauge Pressure

Project Description

Recently, in the range 1 Pa to 15 kPa new KC CCM.P-K4.2012 was performed, and also new pressure standards were established at some NMIs, demanding their equivalence to be demonstrated. This new EURAMET KC should check the equivalence of the new standards. CMI, which participated in CCM.P-K4.2012, will provide a link to CCM.P-K4.2012 for absolute pressure and to former EURAMET.M.P-K4.2010 KC for gauge pressure. CMI's Force-Balanced Piston gauge (FPG) will serve as a transfer standard. However, it will not travel. Instead, each participant will bring its standard to CMI. Alternatively, laboratories whose standards are not movable will make a comparison with the CMI FPG using a suitable travelling standard. Measurements will be done at nominal pressures of 1 (optional), 3, 10, 30, 100, 300, 1000, 3000, 10000, 15000 Pa.
