This report describes the preparation of two wheat reference materials (RM 471 and RM 472) and the certification of their ochratoxin A mass fraction. RM 471 was prepared from uncontaminated wheat material. RM 472 was prepared by blending wheat material naturally contaminated with ochratoxin A with uncontaminated wheat to achieve the desired ochratoxin A mass fraction. Details are given in this report on the milling, blending and packaging procedure and the investigations to verify homogeneity and stability of the materials. The certification exercise was carried out by 15 laboratories using a variety of extraction and clean-up procedures.
