Section 42.10 - Requirements for Maintaining Certification Status

(1) To maintain certification status, a laboratory shall satisfactorily analyze samples from a proficiency testing program administered or approved by the Department and pass inspections conducted or approved by the Department.

(2) A laboratory must continue to meet the Department's minimum standards for certification set forth in 310 CMR 42.00 to maintain certification status.

(3) A laboratory shall not misrepresent its certification status on any document. On reports of sample analysis, the laboratory must clearly distinguish among analyses for which it is certified, analyses for which it is provisionally certified, and analyses for which it is not certified. The laboratory's certification status indicated on a report of sample analysis must be accurate as of the date of the analysis. For all other documents, including promotional materials, catalogues, advertising, Internet sites, business solicitation proposals, quotations, or other materials on which the laboratory's certification status appears, the laboratory, to the extent possible, must correct its certification status appearing on such documents within 30 calendar days of its receipt of a notice of revocation of certification or within 30 calendar days of its voluntary withdrawal from certification.
