The objective of this project is to evaluate comparability in standards and calibration facilities for NH3
This project aims to compare all 3 national institutes’ Primary Standard Gas Mixtures to determine international comparability and traceability.
Nmi, the Netherlands, will prepare a set of NH3 in nitrogen mixtures with a nominal concentration in the range from -90 – 110 exp –6 mol/mol to circulate to the other institutes for comparisons with their national standards.
