Accreditation & Quality Assurance

Letaba Lab led the forefront with Quality Assurance in the Lowveld by being the first ISO/IEC 17025 accredited civil material’s laboratory in the region. Since then, we have undertaken to ensure the same level of quality control and management supervision throughout the group and are now pleased to say that our central (Bloemfontein) and Northern (Polokwane) branches are enjoying the same status.

As the quality management system is constantly evolving and improving along with the governing bodies and regulations, so do Letaba Lab. As such we have improved and updated our system to now adhere to the revised ISO/IEC 17025:2017 Standard.

The benefits of utilizing services from a regulated facility are clearly advantageous to any quality conscience client or project, but here are a few highlighted points:

  • Laboratory accreditation is highly regarded both nationally and internationally as a reliable indicator of technical competence.

  • Laboratory accreditation provides formal recognition to competent laboratories, thus providing a ready means for customers to identify and select reliable testing.

  • To maintain this recognition, laboratories are re-evaluated regularly by the accreditation body to ensure their continued compliance with requirements, and to check that their standard of operation is being maintained.

  • The laboratory is also required to participate in relevant proficiency testing programs between reassessments, as a further demonstration of technical competence.

  • Laboratory accreditation bodies use this standard specifically to assess factors relevant to the laboratory‚Äôs technical competence, including the:

    • technical competence of staff;
    • validity and appropriateness of test methods;
    • traceability of measurements and calibrations to national standards;
    • suitability, calibration, and maintenance of test equipment;
    • ¬†testing environment;
    • sampling, handling, and transportation of test items;
    • quality assurance of test and calibration data.
  • Finally, through a system of international agreements, accredited laboratories receive international recognition.
