Validation of EDF or EDF+ compatibility

Bob Kemp

Some manufacturers have asked me to validate and publish EDF(+) compatibility of their system. So, I have designed a procedure. But first, please save my time and your money and check your files by using this free and easy EDF-header checker for Windows.
 
After that, I am prepared to validate your files. Successfull validation implies that the values in you files (for instance time and calibrations) are EDF(+) compatible, not that they are correct. Validation reports may only be published by myself through my Companies page. Software that is EDF(+) compatible will be highlighted by the EDF(+) logo. Each report and logo will be removed after
3 years, but I will first offer you a 'refresh' validation. Any software that appears to not support EDF(+) (anymore) will be removed. It is your responsibility to inform me of relevant address or other changes.

Requests for validation must be addressed to me. The request should mention:
 
The fee is 1000€ for which I will send an invoice to the owner of the software.  The invoice contains the address to which you must send one CD-ROM with 1-3 EDF(+) files that are produced by the software that is to be validated. The file(s) must include all types of polygraphic signals that are supported by your software. The file must be produced using the exact same procedure as you are offering to the average customer. In fact, most convincing would be that the files come from a lab that is using your system in a routine setting. In that case, I can add the lab, its head and an appropriate email contact at that lab (all information supplied by you) to my report, of course provided they allow me to do so. The files remain my property. I may publish (parts of) it with my report, so you must make sure that no identification of subjects / patients is possible.
 
After reception of payment, file(s) and (optionally) routine lab info, my report on EDF(+) compatibility should be available within 2 months.
I will publish the report on the Companies page and inform you about that.
 
In case of small problems, you and I may agree on a period of a few months during which the report remains there while you make adjustments for another try. If you and I feel that the report contains a clear injustice, we will discuss this and I may produce a modified report. In any case, for instance when there are bigger problems, you or I may decide to have the validated system removed from the page.

 
My colleagues and I are good at EDF and EDF+, but we can make mistakes for which we do not have any insurance. Our understanding of your software and systems is limited. Of course, any obvious mistakes will be corrected when brought to our attention. And I want to provide objective and trustworthy information about EDF and EDF+. But we cannot accept any liability related to this validation. This is not an official certification body. So any damages related to this validation or publication are your own risk.
