CERTIFICATION OF PERSONAL HAND PROTECTIVE EQUIPMENT AGAINST LOW TEMPERATURES

Abstract. The current aspects of certification for personal protective gloves against cold were considered. An analysis of the regulatory framework governing the requirements for thermal insulation properties of such products was conducted, including TR CU 019/2011 and its list of standards. A comparative review of methods for determining the degree of thermal insulation was carried out.

Keywords: personal hand protection equipment, protection from low temperatures, certification, thermal insulation, convective cold, contact cold.

HACCP SYSTEM DEVELOPMENT AND SUBSTANTIATION FOR PRODUCING MEAT-VEGETABLE PATE

Abstract. The issue of ensuring food safety is considered using an example of production of meat-vegetable pate made from poultry meat and liver with the addition of pumpkin puree and a vitamin complex. The technological process is analysed in detail with identifying potentially hazardous factors and assessing quantitative risk. A two-level risk management system that combines preliminary measures programs and local control at critical points is proposed.

Keywords: HACCP system, critical control points, risk analysis, food safety, decision tree, quality management, production risks.

THE USE OF FROZEN READY-TO-COOK MEAT PRODUCTS IN THE PRODUCTION OF DIETARY FOOD

Abstract. The authors present the results of work to optimize dietary nutrition in Moscow medical facilities and describe the processes of transition from the direct preparation of individual portioned beef and poultry products to applying frozen, industrially produced, minced ready-to-cook products. Examples of food layout cards calculating the composition, nutritional, and energy value of products intended for the preparation of optimized meals are provided.

Keywords: quality management, efficiency, layout cards, frozen ready-to-cook meat products, poultry ready-to-cook products, dietary food, medical facilities.

PRINTED CIRCUIT BOARD QUALITY CONTROL USING SCANNING PROBE MICROSCOPY

Abstract. Scanning probe microscopy (SPM) technology plays an essential role in ensuring quality of printed circuit boards and their components. Three main functions of SPM are scanning, spectroscopy, and lithography. A multifactorial approach using various methods allows for identification of defects that are not detectable by traditional quality control means, which significantly increases the reliability and durability of products.

Keywords: scanning probe microscopy, spectroscopy, lithography, printed circuit boards, quality control.

ANALYSIS AND ASSESSMENT OF PIPE PRODUCT DAMAGE RISK DURING TRANSPORTATION

Abstract. The features of analyzing pipe product damage risk during transportation by road are discussed. If regulatory requirements for transportation are violated, the supplier is held liable for any potential losses. Consequently, manufacturers are particularly interested in tools that allow them to objectively assess the likelihood and consequences of a risk, and therefore take effective measures to minimize it.

Keywords: logistics risks, cargo damage, pipe products, automobile transportation, risk identification, methodological tools.

ALGORITHM FOR PROCESSING EXPERIMENTAL RESULTS TO DETERMINE VERIFICATION INTERVAL FOR PRESSURE SENSORS

Abstract. One of the main tasks of improving the quality of metrological services and ensuring the unity of measurements is the correct determination of verification intervals for measuring instruments. The article describes and compares algorithms for solving this problem, developed based on the results of a long-term study on changes in time-standardized metrological characteristics. An example of using one of these algorithms to calculate verification interval for pressure sensors is presented.

Keywords: reference standards for units of measurement, measuring instruments, verification interval, metrological dependability, pressure sensors, instability, regression analysis.
