Abstract

One of the activity areas of JSC “The URIR named after A. S. Berezhnoy” is assistance to refractory industry enterprises of Ukraine in ensuring their work in the quality monitoring of products and raw materials.

The comparison of work quality of chemical­analytical units of following enterprises: JSC “KDZ”, PJSC “Chasovoyarsk Refractory Plant”, JSC “Velikoanadol Refractory Plant” and JSC “The URIR named after A. S. Berezhnoy” was carried out. The discrepancy between the average results of components determination in the chemical­analytical units of refractory enterprises and in the chemical­analytical laboratory of JSC “The URIR named after A. S. Berezhnoy” does not exceed the value of  in terms of ND. The work quality of chemical­analytical units of central refractory laboratories of all the above mentioned enterprises is satisfactory. Recommendations to improve the accuracy of analysis results are not required.

The work on interlaboratory comparison of work results of the chemical­analytical unit of JSC “The URIR named after A. S. Berezhnoy” and IP “SGS Ukraine” was completed. The quality of interlaboratory comparisons carried out between the Testing Centre of IP “SGS Ukraine” and JSC “The URIR named after A. S. Berezhnoy” was found to be satisfactory. The test results were accepted by the NAAU during the next inspection as corresponding to DSTU ISO / IEC 17025:2006.
