Final report APMP. M. M-K 6 Comparison of Mass standards multiples and submultiples of the kilogram 1 kg, 500 g, 2 g and 100 mg (Class OIML E 2). The list of participants are : 1. Vietnam Metrology Institute (VMI) 2. South Africa National Metrology Laboratory (CSIR-NML, CSIR for short) 3. Syria National Standards and Calibration Laboratory (NSCL) 4. National Measurement Institute, Australia (NMIA) 5. Industrial Technology Development Institute (ITDI) 6. National Institute of Metrology Thailand (NIMT) 7. Mongolia Agency for Standardization and Metrology (MASM) 8. Egypt National Institute for Standards (NIS) 9. Measurement Units, Standards and Services Department (MUSSD) 10. Nepal Bureau of Standards and Metrology (NBSM) 11. National Physical Laboratory of India (NPLI) 12. National Physical & Standards Laboratory of Pakistan (NPSL) 13. Indonesian Institute of Sciences (KIM-LIPI) 14. Industrial Laboratory Center of Cambodia (ILCC) formerly Cambodia Department of Metrology (Do. M-MIME) 2

This report summarizes the results of a comparison of Mass Standards conducted between fourteen participating members of the Asia-Pacific Metrology Program. Two weights sets with five nominal mass values: 1 kg, 500 g, 2 g, and 100 mg (OIML Class E 2) were used as travelling artifacts. These nominal values were chosen as they followed the nominal values of CCM. M-K 1 and CCM. M-K 2 except the 10 kg. 3

Mass values assigned by the participating laboratories with bars representing expanded uncertainties. Zero mass value corresponds to the key comparison reference value of CCM. M-K 2. The uncertainty of the reference value is 8 μg (k=2). 4

The program was sponsored by Physikalisch. Technische Bundesanstalt (PTB) and Vietnam Metrology Institute, VMI was the coordinating laboratory with National Measurement Institute (NMIA) being a technical assisting laboratory as well as a link The Draft B report was sent Dr Philippe Richard, Chair of the working group on mass of the CCM. He suggested a few minor modifications. After incorporating his comments, it was sent to Dr. Claudine Thomas, Coordinator, KCDB, BIPM on 10 th October, 2008. It appeared on 24 th Oct. 2008 5

K 6 All headers All attachments Dear AKB, This is to inform you that the results of key comparison APMP. M. MK 6 are now published in the KCDB, as may be seen by clicking here. I have also initiated the issue of the corresponding Metrologia Technical Supplement. The results for 1 kg are now added on the graph of equivalence of CCM. M-K 1, which had already been extended with results of four other RMO key comparisons. This graph is by far the most complete on the KCDB, with 74 degrees of equivalence all together! Thank you very much for your help on this, Claudine 6

PTB / APMP-DEC pressure comparison: The pressure comparison project will provide an opportunity for the DEC NMIs which have no earlier experience in any pressure comparison to become prepared for a comparison and gain greater confidence in their measurement capabilities towards achieving international recognition. NML-SIRIM is the pilot laboratory. APMP-DEC preparatory workshop in SEPANG, MALAYSIA (November 5 ~ 7, 2007) BSTI (Bangladesh), NBSM (Nepal), NIMT (Thailand), NCSL (Syria), JMM (Jordon), NPSL (Pakistan), VMI (Vietnam), KIM-LIPI (Indonesia), ITDI-NML (the Philippines) and MUSSD (Sri Lanka). 7

Movement of the transfer standard to date 8

Loss of ATA Carnet NML-SIRIM completed the measurements in April 2008 and despatched the transfer standard to Indonesia in early May 2008. However, there was a delay of almost two months before KIM-LIPI managed to clear the transfer standard with the Indonesian customs. During this transition it was discovered that the ATA Carnet could not be traced. 9

Future Plan of Intercomparison 10

. Three NMIs among the participating NMIs (in this preparatory workshop) which have never participated in any key comparison before. They are NML-ITDI, NPSL and MUSSD. These NMIs need some technical assistance from other NMIs to prepare themselves better for the forthcoming intercomparison 11

An estimate of expenditure: Case A Two scientists from Srilanka and two scientists from Bangladesh = Total four person 1) Airfare four person US$500 x 4 = US$2000 2) Daily Allowance for four scientists for 14 days [@US$50] = US$ 2800 3) Guest House Charge + Food for 14 days [@US$50] = US$ 2800 Total = US$ 7600 Case B If expert visits to Srilanka and Bangladesh for 4 working days + 1 day transit 1) Airfare for Srilanka US$500 x 2 = US$1000 2) Daily Allowance 5 days (Srilanka) + 5 Days ( Bangladesh) [@US$50] = US$ 500 3) Hotel Charge for 10 days [@US$100] = US$ 1000 Total = US$ 2500 12

Status report APMP. M. M-S 1 program. It was agreed that for the Mass Comparison the pilot laboratory will be NPSL, Pakistan. The inter laboratory comparison in Mass Standards in the SAARC region will be similar to that of APMP. M. M-K 6 and uses a set of three weights of nominal mass 1000 g, 20 g, 100 mg of Class E 2 while the participating laboratory can use their F 1 or F 2 class weights in this inter comparison. The participating laboratories are NPSLPakistan, NPL-India, MUSS-Sri. Lanka, BSTIBangladesh, NBSM-Nepal. 13
