# Commission Delegated Regulation (EU) 2019/331 of 19 December 2018 determining transitional Union-wide rules for harmonised free allocation of emission allowances pursuant to Article 10a of Directive 2003/87/EC of the European Parliament and of the Council (Text with EEA relevance), Division 3.3: Measurement instruments or procedures not under the operator's control

Extent: E+W+S+N.I.

The operator may make use of measurement systems or analytical procedures outside the operator's own control:
(a)where the operator does not have their own measurement instrument or analytical procedure available for the determination of a specific data set;
(b)where determination of a data set by the operator's own measurement instruments or analytical procedures is technically not feasible or would incur unreasonable costs;
(c)where the operator demonstrates to the satisfaction of the regulator that the measurement system or analytical procedure outside the operator's control gives more reliable results and is less prone to control risks.
To that end, the operator may revert to one of the following data sources:
(a)amounts from invoices issued by a trade partner, provided that a commercial transaction between two independent trade partners takes place;
(b)direct readings from the measurement systems;
(c)use of empirical correlations provided by a competent and independent body, such as equipment suppliers, engineering providers or accredited laboratories.
