Laboratories must be registered in a database to be able to participate in any of the schemes. The organiser will do the registration after obtaining the application form from below.
A registered laboratory can choose to 1) be a subscriber of all rounds in a scheme, 2) be a subscriber of specific series (e.g. April, September) and be automatically reckoned as a participant in coming rounds of that series or 3) actively register for individual rounds of interest. The registration or cancellation for a particular round has to be done on the page Participation of this website after logging in.
After registering the laboratory will obtain a confidential laboratory number. The number is the identification key in all communication and in reports. Besides, the laboratory will obtain a confidential password, which must be used, together with the laboratory number, to log into this website as a participant.
If a registered laboratory wants to be removed from the database it has to inform the organiser by letter or e-mail. The laboratory number has to be stated.
