This part of ISO 24631 provides the means of evaluating the conformance with ISO 11784 and ISO 11785 of RFID (radiofrequency identification) transceivers used in the individual identification of animals. It also specifies the procedure for applying for a transceiver test approval and the associated rights and obligations of the parties involved. This part of ISO 24631 includes a wireless synchronization test applicable to mobile transceivers; however, it contains no provision for evaluating the wired synchronization of stationary transceivers. The test procedures specified in this part of ISO 24631 are recognized by the FECAVA (Federation of European Companion Animals Veterinary Association) and WSAVA (World Small Animal Veterinarian Association) and, as such, can be applied also to companion animals.
