The Importance of Accreditation and Proficiency Testing

The ISO/IEC 17025 standard sets out the general requirements for the technical competence of testing and calibration laboratories. This standard ensures that accredited laboratories operate impartially and reliably, following consistent procedures that guarantee the accuracy and validity of the results obtained. Accreditation under this standard aims to ensure that laboratories not only meet the minimum established requirements but also promote a culture of continuous improvement and process review.

One of the pillars of the standard is participation in proficiency testing, also known as interlaboratory comparisons or ring trials. These tests allow laboratories to demonstrate that their results are accurate and internationally comparable. In fact, participation in these programs is not only recommended but also a key requirement for maintaining accreditation. In the field of disinfectant and antiseptic testing, participation in these exercises is essential to ensure the quality and efficacy of the products evaluated.

Furthermore, es imperative the participation by accredited provider under ISO/IEC 17043 to guarantee the quality and reliability of the results. SHAPYPRO is the only one proficiency testing provider accredited over the world.

Intercomparison Programs

Intercomparison programs, including ring trials, are exercises that assess the technical competence of laboratories by comparing results obtained by different laboratories under controlled conditions. The main objective of these programs is to detect systematic errors or biases that may compromise the validity of results. These programs provide an independent external evaluation of laboratory performance, offering an opportunity to identify areas for improvement and apply corrective measures. This not only improves the accuracy of results but also enhances the laboratory's reliability and reputation, ensuring that it operates under internationally recognized standards.

Participation in these tests is essential to ensure that laboratories keep their processes under control and meet the requirements set by ISO/IEC 17025. Proficiency tests can take different forms, such as interlaboratory comparisons, where exercises are organized between two or more laboratories, or tests conducted by accredited providers offering standardized evaluations to measure performance. Moreover, in cases where no programs are available for a specific area, internal proficiency tests can be organized, or alternatives sought to validate the laboratory's technical competence.
