The article considers the issue of ensuring the reliability of measurements in testing and calibration laboratories by implementing a structured methodology for assessing the suitability of methods (methodologies) based on verification and validation procedures. The sequence of assessment stages is presented - from planning, selection of the methodology and analysis of calibration requirements to conducting experimental studies, determining accuracy parameters, estimating uncertainty and making a decision on the suitability of the method. The criteria used in the analysis of calibration results are described in detail, in particular, determining confidence intervals, estimating errors, checking the acceptability of results according to the En criterion, as well as the procedure for documenting the procedure in accordance with the requirements of regulatory and technical documents. The work systematizes the factors that affect the metrological quality of measurements, including the choice of measuring instruments, the qualifications of performers, the conditions for conducting measurements and the correctness of the application of methods. The proposed assessment system allows you to reduce the probability of errors, increase the accuracy and reproducibility of results, as well as ensure compliance of measurement processes with the requirements of DSTU EN ISO/IEC 17025:2019 and other regulatory documents. The results obtained can be used by laboratories to improve their internal quality system, increase the reliability of test equipment and optimize calibration processes.

A quarter of a century signifies a big block of one's business experience, but it has passed, and with it the majority of those early patrons.I am impressed with the events that have been crowded into those busy, hard-working years, and gratefully acknowledge the confidence and good will of my friends, who have enabled me to develop a large business in seeds and farm supplies.At the opening of this silver anniversary year and the beginning of a new century, an opportunity is afforded to compare tne methods of producing and handling seeds with those of nearly half a century ago, when as a boy I had my first experience in seed growing.There were few regular seed growers who depended exclusively upon that industry for their income, and less seed stores devoted entirely to the details of the seed trade.It was the custom then for the wide awake and enterprising farmer, or gardener, to set his roots or sow the seeds of his specialties every second or third year, and sell or exchange the surplus product above his own requirements among his neighbors and friends for their favorite productions, that he might require.The growing of seeds has become a vast industry, and can no longer be handled in an indifferent and careless manner with any chance of success.The most intelligent, pains- taking efforts alone insure satisfactory results, and it has been my aim to secure the services of those whose years of experience entitle them to be classed as expert seed growers to han- dle my contracts.By this careful discrimination I have been enabled to offer only the best of everything in the line of field, garden and flower seeds that can.possibly be produced.
