ISO 17025, ANSI/NCSL Z540-1
For testing and calibration laboratories seeking recognition and credibility within their field of expertise, accreditation to national and international laboratory standards criteria ultimately becomes necessary. Preparation for accreditation involves developing and maintaining a specified quality program that includes complete quality system documentation, with quality manual and policy, corrective action and internal audit systems, together with management review of the quality system. The laboratory must develop and maintain ongoing proficiency studies through interlaboratory comparisons, use of certified reference materials, replicate testing and correlation methods. The laboratory must establish and maintain uncertainty determinations that state the precision or repeatability for all of the test methods employed.
If your laboratory is contemplating accreditation to a national or international standard, e.g. ANSI/NCSL Z540-1 or ISO 17025, we can help. We have successfully assisted laboratories in gaining accreditation to these standards.
