Abstract This paper describes the preparation, homogeneity studies and certification of a series of two paint reference materials (mild steel coated with alkyd resin paint, CRM620, and comminuted paint from alkyd resin paint, CRM623) which have been produced in support of the EU Toy Safety Directive (88/378/EEC). The reference materials have been certified for levels of toxic element migration using the method specified in European Standard EN71-3:1994 published by the European Committee for Standardization. As such, the certified values, indicative values and range data quoted for the reference materials in this paper are method specific and relate only to European Standard EN71-3:1994. The paper summarizes the analytical work carried out and gives a description of the analytical methods used to measure As, Ba, Cd, Cr, Hg, Pb, Sb and Se, the 8 toxic elements specified in European Standard EN71-3:1994, in the sample extracts. Descriptions of the reference materials, certified values, indicative values together with their associated uncertainties or range of laboratory means as appropriate are given. The preparation of a (not certified) reference material (beechwood coated with nitrocellulose paint, RM621) is also described and assigned values for As, Ba, Cd and Se are given. The Hg content could not be certified in any of the reference materials, owing to a high dispersion of results.
