Show affiliationsThis comparison, APMP.QM-K3, is intended to be an equivalent RMO key comparison in the APMP (Asia Pacific Metrology Program) region and uses basically the same protocol as CCQM-K3. Four national metrology institutes, CSIR-NML (South Africa), CMS-ITRI (Taiwan), KRISS (Republic of Korea) and NMIJ/CERI (Japan), participated in the key comparison. ERL-HIAST (Syria) participated as a 'study' and the results will not be included in MRA Appendix B. APMP.QM-K3 was organized by the Korea Research Institute of Standards and Science (KRISS). The selected primary gas mixtures for this comparison were individually prepared using gravimetry and thoroughly studied for their chemical composition and stability. The comparison was carried out at an amount-of-substance fraction level of 28 mmol/mol carbon monoxide, 124 mmol/mol carbon dioxide and 1.95 mmol/mol propane in nitrogen (balance gas). All laboratories participated as key comparison submitted results that were within ±1% relative to the gravimetric value. The results of this comparison are linked to the key comparison CCQM-K3 through the link laboratories: NMIJ/CERI and KRISS.
