Following the IMEKO World Congress 2027, parallel Special Issues will be opened in:

• Measurement
• Measurement: Sensors
• Measurement: Digitalization
• Measurement: Food
• Measurement: Energy
• ACTA IMEKO

Unlike in previous editions of the IMEKO World Congress, no formal selection or invitation process will be applied. Authors of eligible World Congress papers may submit an extended version of their work to one participating journal only.

The present instructions are preliminary and will be updated with more precise information and dates, when the Call for Special Issue papers of the different journals and the submission deadlines are formally announced.

In agreement with the Publisher, the following Article Processing Charge (APC) discounts will be offered to the papers submitted and accepted for publication in the following journals: 

• Measurement: Sensors – 50% APC discount
• Measurement: Digitalization and Measurement: Energy – 40% APC discount
• Measurement: Food: – 30% APC discount

Moreover, IMEKO members will be eligible for an additional 30% discount if they are the corresponding authors of the paper. Note that no open-access APC discounts will be offered to the Authors of papers accepted in Measurement. Finally, ACTA IMEKO is a diamond open-access journals. So no APCs shall be applied   

IMPORTANT: considering the massive amount of expected submissions and to ensure a reasonable balance between journals, depending on paper topic, editorial capacity, and the Reviewers’ scores of the conference proceedings papers some manuscripts (particularly a fraction of those submitted to Measurement, where the maximum numerosity is expected) may be transferred to another participating journal.

Decisions on suitability, transfer, or desk rejection will be made by the Guest Editors, in coordination with the relevant journal editors, and will be final. Manuscripts passing the initial assessment will undergo the standard peer-review process of the receiving journal.

The opportunity to submit a special issue paper is open only to Authors of papers that were:

• accepted for the IMEKO World Congress 2027;
• covered by a valid registration; and
• actually presented at the Congress.

Papers recorded as a no-show by the Session Chair during the IMEKO World Congress will not be eligible for a any special issue submission.

The journal manuscript must contain at least 30% new and technically significant content.

Extensions limited mainly to the introduction, references, background material, minor discussion, or other ancillary aspects will not be considered sufficient, even when the manuscript is more than 30% longer.

In addition, 

• the IMEKO World Congress proceeding paper must be properly referenced and 
• the total similarity score of the paper must not exceed 40%. 

Manuscripts violating these rules may be rejected.

The cover letter of any paper submitted to one of the special issues must include:

• conference paper ID, title, and authorship;
• a bulleted list and a clear explanation of the technical extensions; 
• justification for any change in authorship;
• a declaration that the IMEKO World Congress  proceeding paper is cited in the manuscript. 
• a declaration that the paper was not submitted to other journals and it is original except for the parts related to the IMEKO World Congress proceeding paper.

Unjustified authorship changes, missing information, or an unclear description of the extension will lead to desk rejection.
