Wageningen University is accredited for the organization of Interlaboratory Studies by the Dutch Accreditation Council RvA under registration number R002. The accreditation is based on the ISO/IEC- requirements (General requirements for proficiency testing, ISO/IEC 17043:2010). Determinands only meet the criteria for accreditation if the results are reported by a sufficient number of participants for at least three years and the results have proven to be homogeneous and stable.

Determinands that are not in bold are not subject to accreditation.
