THE MINERAL WATER TESTS METHODS METROLOGICAL ANALYSIS AND THE PROPOSALS ON THEIR IMPLEMENTATION IN UKRAINE

Abstract

In connection with the necessity to unify the procedures and requirements applicable to goods and services, first of all, with regard to conformity assessment, in order to eliminate technical barriers to trade, a list of methods for testing mineral waters has been analyzed, according to which their assessment of conformity and determination of individual safety and quality indicators. The paper analyzes the metrological characteristics of the methods approved in the form of international, national standards, standards adopted before 1992, test methods for assessing their suitability for implementation not only in the testing, but also in the production laboratories. According to the results of the analysis of 42 indicators of the measurement methodology, which are specified in DSTU 878-93 (regulatory document on packaged mineral water) and GSTU 42.10-02-96 (normative document on medical waters used in sanatorium practice), 13 indicators , which are mandatory, as they are specified in the relevant normative documents, are not valid. According to the results of the analysis of the metrological characteristics of the methods of testing the indicators of safety and quality of mineral waters, a list of methods of tests of mineral waters for the period 2019-2021 has been developed, which includes national standards certified in Ukraine methodology and GOST for drinking water, in particular, on sulfates, ammonium and iron . However, the effect of these GOST on the testing of drinking water after 2021 will be abolished, and they should also be replaced either internationally or to develop national standards. In selecting the methods of testing mineral waters, two aspects were taken into account: the conformity of metrological characteristics of the methods during the assessment of the conformity of mineral waters, taking into account the features of the composition of the mineral water itself (applicability of the method for both low and high mineral waters), and the economic feasibility of testing for the appropriate method (due to the impossibility of many testing and production laboratories to use high-value equipment). In order to provide modern standards (international and national) of packaged mineral water producers and test laboratories conducting an assessment of the conformity of mineral waters, a list of methods for testing mineral waters, which is to be developed in Ukraine for the replacement of interstate GOST or methods, the metrological characteristics of which do not correspond to the current one, is proposed. in Ukraine the rules of legal metrology, and to give them the status of national standards (for the definition of Pseudomonas spit, sulfates, ammonium, bro copper and iodide). This will enable Ukrainian producers of packaged mineral water to optimize production costs for the production of Ukrainian products and successfully expand its share in the foreign market.
