This paper reports the results of measurements performed on seven standard weights by 15 metrology laboratories throughout Romania. The goal of the Inter-laboratory's measurements was to provide verification of each participating laboratory's measurement capability by obtaining a measurement that agrees with the pilot laboratory.
The comparison began in 2005 and concluded in 2006, the National Institute of Metrology (INM) acting as a pilot (coordinating) laboratory for the programme.
Seven mass standards (nominal values: 10 kg, 1 kg, 500 g, 200 g, 100 g, 20 g and 100 mg) were sent to the participants.
The results are analyzed using En values.
The laboratory's results are presented for each weight, uncertainty declared and the errors normalized by each laboratory, with respect to the INM.
