CSIRT stands for Computer Security Incident Response Team.
In Europe, there are multiple national CSIRTs which are part of the European Union CSIRTs network.
But Article 12(1) of the NIS 2 Directive states that each European country must designate a single CSIRT to manage coordinated vulnerability disclosures.
In the context of the CRA, that CSIRT is the relevant CISRT that is referenced throughtout the text and defined as the CSIRT designated as coordinator in Article 3(51).
If you are headquartered in Europe, you can easily find the relevant CISRT on the member section of the network's website.
If you are not headquartered in Europe, Article 17(4) explains the criteria manufacturers should use to identify the relevant CSIRT.
