About ISO/IEC 17025

ISO/IEC 17025 is the international standard that contains all of the requirements that testing and calibration laboratories have to meet if they are to demonstrate that they operate a quality system, are technically competent and are able to generate technically valid results. The 17025 standard is focused on legally responsible entities that provide test and calibration services, either as a stand-alone business or as a part of a larger organization.

The ISO/IEC 17025 accreditation includes all of the elements of ISO 9000 but then goes on to ask:

  •  Are appropriate test procedures in use?
  •  Will the procedure produce accurate results?
  •  Are the procedures validated to produce accuracy?
  •  Are effective quality control procedures in effect?
  •  Is there an understanding of the science?
  •  Do the procedures have limitations?
  •  Are technical deviations foreseen and are there coping mechanisms?
  •  Does the lab have all of the appropriate equipment to perform the described procedures?

The ISO/IEC 17025 accreditation indicates technical credibility and an expectation of valid results for specific tests or calibrations. Laboratories with ISO 9000 registration alone cannot make the same claim.

Accreditations

OCS is accredited by the Laboratory Accreditation Bureau (L-A-B) to the demanding ISO/IEC 17025:2005 standard for calibration laboratories.

International recognition is obtained through the International Laboratory Accreditation Cooperation Mutual Recognition Agreement. The ILAC MRA insures that a certificate issued by an LAB accredited lab is accepted nationally and internationally in the same manner as if it were issued by a lab accredited by A2LA, ACLASS, UKAS, NVLAP and more than 65 other accrediting bodies world-wide.
