description: A list of general minimum criteria was developed to be used in preparation of reference materials to be used in interlaboratory testing, including validations through test performance studies. The list was based on previously identified criteria in standards including ISO standards, EPPO guidelines, deliverables of relevant projects, related fields, and own experience of project partners. Several additional criteria were proposed: ‘availability’, ‘purity’ and ‘commutability’. These criteria result from a series of discussions, taking into account previous work and relevant international standards. Where relevant, each criterion was first defined as a series of levels from the highest to lowest ranking with the lowest ranking considered to be the minimum. Depending on the intended use, the reference material may need to fulfil higher levels of selected criteria or some criteria may not be relevant at all. The criteria were tested by the organizers of the TPS in round 1 of validation within VALITEST project which include bacteria, viruses, nematodes and fungi. The systematic and structured approach of describing RMs was found to be useful in promoting transparent descriptions of the RMs used and comparability of TPSs, as well as a step toward implementing FAIR data principles. The criteria defined here are applicable, potentially with minor modification, beyond the scope of this deliverable and project to other pests and other uses of RMs. A list of general minimum criteria was developed to be used in preparation of reference materials to be used in interlaboratory testing, including validations through test performance studies.
