Fields of accreditation: certification and registration

Fields of accreditation: certification and registration. (1) General. The department shall certify and register laboratories by specific fields of accreditation. Accreditation shall be by certification under s. 299.11 (7) , Stats., or registration under s. 299.11 (8) , Stats. Fields of accreditation consist of 3 tiers describing the analytical capability of laboratories. (2) Tier 1 – matrix. The first tier of accreditation is comprised of aqueous, non-aqueous, and drinking water matrices. (3) Tier 2 – technology or method. (ag) The second tier of accreditation is comprised of analytical technologies for the aqueous and non-aqueous matrices or methods for the drinking water matrix. (ar) The department may certify or register laboratories that analyze aqueous and non-aqueous matrices for the analytical technologies contained in this section, Table 1. (b) The department shall include any associated sample preparation techniques, such as digestions, distillations, extractions, cleanups, concentrations, and dilutions as part of the certification or registration for a given field of accreditation. (c) Laboratories may employ multiple methods of analysis for a given analytical technology under the same field of accreditation. (d) The department may certify laboratories analyzing drinking water samples using methods promulgated or approved by the EPA under 40 CFR Part 141 . (4) Tier 3 – analytes or analyte group. (ag) The third tier of the accreditation is comprised of analytes or analyte groups. The department may certify or register laboratories by analyte groups if it improves the efficiency of administering accreditations. (ar) The analytes and analyte groups available for accreditation under this subsection are contained in Appendix I. (b) The department, upon consultation with the council, may offer accreditation for additional analytes or analyte groups that are not contained in Appendix I upon request by the manager of a covered program or when the EPA requires the additional analytes or analyte group analysis. (c) For aqueous and non-aqueous matrices, the analytes and analyte groups are organized into classes. Laboratories analyzing aqueous and non-aqueous matrices may be accredited for analytes and analyte groups belonging to the analytical classes contained in this section, Table 2. (d) For the drinking water matrix, the analytes and analyte groups are organized into classes. Laboratories analyzing drinking water may be certified for analytes or analyte groups belonging to the analytical classes contained in this section, Table 3.
