The methodology of analysis regarding the results of interlaboratory testing
Metodologija analize rezultata međulaboratorijskih ispitivanja
Apstrakt
The paper presents the analysis of results of inter-laboratory proficiency tests performed in accordance with standard ISO 5725. The methodology for evaluation of each individual laboratory through definition of critical interval and deviation coefficient Z is presented together with methodology for determination of repeatability and reproducibility through calculation and graphical presentation of Mendel's parameters 'h' i 'k' and statistics of Cochran's test 'C'. The approach is illustrated through analysis of results of interlaboratory testing for evaluation of characteristics of asphalt mixes in which 4 accredited laboratories have participated and which was initiated by the Laboratory for roads and geotechnics of the IMS Institute. .
U radu je prikazan postupak analize rezultata međulaboratorijskog uporednog ispitivanja u skladu sa standardom ISO 5725. Posebno su obrađeni metodologija za vrednovanje rada pojedinih laboratorija preko određivanja kritičnog intervala i koeficijenta odstupanja Z, kao i određivanje ponovljivosti i reproducibilnosti preko definisanja i grafičke predstave Mendelovih parametara 'h' i 'k' i određivanja statistike Košranovog testa 'C'. Postupak je ilustrovan na analizi rezultata međulaboratorijskog uporednog ispitivanja karakteristika asfaltnih mešavina, u kome su učestvovale 4 akreditovane laboratorije, a inicijator je bila Laboratorija za puteve i geotehniku Instituta IMS u Beogradu. .
