Benefits of Accreditation:

Formal recognition of competence of a laboratory by an Accreditation body in accordance with international criteria has many advantages:

  • Increased confidence in Testing/ Calibration Reports issued by the laboratory.
  • Better control of laboratory operations and feedback to laboratories as to whether they have sound Quality Assurance System and are technically competent.
  • Potential increase in business due to enhanced customer confidence and satisfaction.
  • Customers can search and identify the laboratories accredited by NABL for their specific requirements from the NABL Web -site or Directory of Accredited Laboratories.
  • Users of accredited laboratories enjoy greater access for their products, in both domestic and international markets.
  • Savings in terms of time and money due to reduction or elimination of the need for retesting of products.

The benefits of proficiency testing are widely recognized. These include:

  • Comparison of a facility’s performance with that of other participating (peer) facilities
  • Monitoring of a long-term facility performance
  • Improvement in the performance of tests/calibrations following investigation and identification of the  cause(s) of unsatisfactory PT performance, and the introduction of corrective action to prevent re- occurrence
  • Staff education, training and competence monitoring
  • Evaluation of methods, including the establishment of method precision and accuracy
  • Estimation of measurement uncertainty
  • Contribution to the facility’s overall risk management system
  • Confidence building with interested parties, e.g. customers, accreditation bodies, regulators, specifiers.
