AFRIMETS.EM-S3: Bilateral comparison between NMISA and KEBS on resistance standards at 1 Ω, 10 Ω, 100 Ω, 1 kΩ and 10 kΩ

Abstract

Main textThis is a follow-up comparison between NMISA and KEBS of AFRIMETS.EM-S1 (resistance standards at 1 Ω, 10 Ω, 100 Ω, 1 kΩ, and 10 kΩ), published in KCDB in February 2022. This follow-up comparison uses a different set of standard resistors from the main comparison. After completion of the supplementary comparison (AFRIMETS.EM-S1), KEBS was not satisfied with their comparison results because they did not support their required measurement capabilities. KEBS purchased a new resistance measurement system as part of the corrective action and requested a follow-up bilateral comparison with NMISA. This report describes the detailed findings and results of the comparison in terms of behaviour of travelling standards, methods used by participants and measurement results.To reach the main text of this paper, click on Final Report.
