Accreditation
Gamal A. Hamid
ISO 17025
64
Accreditation benefits
• Your laboratory will gain international recognition for its commitment to quality,
• you comply with an internationally recognized standard, thus easing the global exchange of
valuable information.
• Accreditation is an objective way to assure your customers that you have demonstrated
technical competence to provide reliable and accurate test or calibration results.
• third party accreditation body performs annual assessments to verify whether your system is
meeting all of the requirements of ISO/IEC 17025.
• Otherssssssssssssssssssssssssssssssssssssssssssssss.
Gamal A. Hamid
ISO 17025
65
Accreditation Steps
• A laboratory must document a quality management system.
• A documented quality manual is a basic requirement on the road to laboratory accreditation.
• In addition, quality management procedures must be established for how the system is
maintained.
• Once the system is documented it must be implemented in the laboratory.
• It will also accompany the laboratory’s application for accreditation.
• The implementation period will require several months to establish the records that an
accreditation body will review at an accreditation audit.
• Finally, the laboratory undergoes the ISO17025 assessment by an accreditation body that is
certified to perform laboratory accreditation.
