Deliverable 3.5 – Interim report on validation of new or modified test protocols and test methods

WP3 aims to experimentally validate and update existing research protocols and standards for measuring the quality and quantity of hydrogen and H₂NG blends, addressing current gaps. It adopts a rigorous approach to confirm the suitability of new testing methods before they are introduced. The main goal is to validate innovative protocols for evaluating measurement equipment performance. Task 3.2 focuses on experimental validation of new or adapted test methods on devices selected in Task 2.1, using interlaboratory comparisons when possible. Validated methodologies will be used in Task 3.3, with collaboration among consortium laboratories and partners to ensure successful implementation.
