Abstract

This paper shows the results of an interlaboratory comparison in Thailand for weight conducted three times. At the first starting from October 2001 to December 2001, eleven participating laboratories joined in OIML weight 500 g F1 and brass weight 500 g programs. Next, from October 2003 to February 2004, F1 OIML weights of 100 mg, 10 g, 1 kg and 5 kg were calibrated among sixteen participating laboratories. At last, started from May 2006 to July 2006 with two sets of F1 OIML weights : 100 mg, 2 g, 20 g, 50g and 1 kg, seventeen laboratories participated. The National Institute of Metrology (Thailand), NIMT, Mass Laboratory under the Department of Mechanical Metrology was a pilot laboratory, which as the coordinating interlaboratory on these three programmes, carried out to check the results on these artifacts at the beginning, the middle and the end of circulating loop. The report of these comparison is being in this document.
