Renewal of the Declaration of Equivalence with NIST


We are very proud to be the only national metrology institute in Europe with this type of declaration, to deliver value to companies operating in both Europe and the USA.

Why do these declarations matter? 

International co-operation is critical in metrology. We need to know that measurements for compounds like nitrogen and CO₂ mean the same thing in different parts of the world - and that we can trust those measurements.

This is why Declarations of Equivalence exist, in which metrology institutes find common grounds - so you know that an m3 of gas means the same thing at home and on the other side of the world!
