Interlaboratory Comparison (LAK) and Proficiency Testing Programs
TS EN ISO/IEC 17043 compliant LAK programs for aggregate, concrete, water and environmental analysis laboratories
Interlaboratory Comparison (LAK/ILC) programs objectively demonstrate a laboratory's technical competence by comparing its measurement and test performance with other laboratories in the same field. Conducted under TS EN ISO/IEC 17043, these programs are specifically designed for aggregate, concrete and concrete products, drinking and process water, and environmental analysis laboratories.
Laboratory Areas We Serve
Accredited and pre-accreditation laboratories in the following fields can benefit from our LAK programs.
Aggregate and construction materials testing laboratories
Concrete and concrete products (precast, paving blocks, kerbs, etc.) laboratories
Drinking water, process water and wastewater analysis laboratories
Environmental analysis and emission measurement laboratories
Benefits of LAK Participation
Verify your laboratory test results through an independent and objective method
Meet accreditation and quality management system (ISO/IEC 17025) requirements
Detect deviations in personnel competency and instrument performance at an early stage
Demonstrate your technical competence to customers and regulatory bodies
How Does a LAK Program Work?
A suitable LAK program is identified based on your laboratory's scope of activity
Homogeneity- and stability-tested reference samples are dispatched to your laboratory
Your laboratory performs measurements and tests according to standard procedures
Results are evaluated using statistical methods (z-score, En value, etc.)
A performance report is prepared and delivered under principles of impartiality and confidentiality
Referans Standart
TS EN ISO/IEC 17043:2010
All our LAK programs are designed and conducted in accordance with TS EN ISO/IEC 17043. Your result reports can be used directly in your quality management system documentation.
