On 30 November 2016, the European Commission presented a new package of measures with the goal of providing the stable legislative framework needed to facilitate the clean energy transition and towards the creation of the Energy Union. Some of the measures are now nearing their publication, including the revision of a few revised directives.

The white paper details a total of five uncertainties that can occur during the measurement process. In addition to errors in measuring instruments, it looks at both uncertainties in the reproducibility of tests in different laboratories and in the manufacture of compressors. Moreover, the document also highlights the uncertainties in performance prognosis as well as the difference between nominal and test conditions.

The European Commission services together with stakeholders have recently produced guidelines to assist in the smooth and level application of the Directive 2014/35/EU. The Directive became applicable on 20 April 2016. The guidelines explain in an easy and understandable way the elements of the Directive.
