Control of the work quality of chemical and analytical departments of the refractory industry enterprises of Ukraine in 2019

Control of the work quality of chemical and analytical departments of the refractory industry enterprises of Ukraine is one of the activity areas of JSC "The URIR named after A. S. Berezhnoy" and helps to increase the competitiveness of products manufactured by enterprises.The comparison of work quality of chemical-analytical units of refractory 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 chemical analysis in the chemical-analytical unit of refractory enterprises and in the laboratory of chemical-analytical and structural-phase research of JSC "The URIR named after A. S. Berezhnoy" does not exceed the permissible value of γ in terms of SОU-N МPP 77.080-012:2004. The work quality of chemical-analytical units of central refractory laboratories of all the above mentioned refractory enterprises is satisfactory. Recommendations for improving the accuracy of the chemical analysis results in the refractory enterprises laboratories that participated in the tests are not required.

Interlaboratory comparisons of the results of the work of the chemical­analytical unit of JSC “The URIR named after A. S. Berezhnoy” in 2018

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.

External quality control of chemical-analytical units of refractory enterprises in 2016

External quality control of the chemical-analytical departments of the central factory laboratories was carried out: PJSC Krasnoarmeysky Dinas Factory, PJSC Chasovoyarsk Refractory Plant, PJSC Velikoanadol Refinery Plant. During the chemical analysis of samples of refractories of the listed enterprises, the analysis methods, equipment and materials described in DSTU 3305(3, 4, 5)—96 (GOST 2642.(3, 4, 5)—97) — gravimetric (SiO2), complexometric (Al2O3), photometric (Fe2O3). As a result of the work carried out, conclusions were drawn up in which the quality of the work of the chemical analytical units of the central factory laboratories of the PJSC “Krasnoarmeysky Dinas Factory”, PJSC “Chasovoyarsk Refractory Plant”, and PJSC “VELIKOANADOL REFRACTORY PLANT” was considered satisfactory.
