The purpose of the research work is to analyze the advantages and disadvantages of the «flexible» field of accreditation of forensic laboratories and the field of accreditation that has a rigid range. The development of standardization in forensic science, including the expansion of the number of forensic laboratories that build their activities in accordance with the requirements of the international standard GOST ISO/IEC 17025-2019 «General requirements for the competence of testing and calibration laboratories», encourages us to pay attention to this issue again. In the course of the study, the following conclusions were formulated. Insufficient clarity in defining the «flexible» scope of accreditation and differences in the understanding of its boundaries by the accreditation body, the forensic laboratory and the customer can lead to abuse by individual laboratories and the development of unfair competition. This argument in favor of abandoning the «flexible» field of accreditation for forensic laboratories seems to be much more weighty than the listed advantages of its practical application.

The updated version of the ISO/IEC 17025 standard has introduced substantial changes to the structure, terminology, requirements to resources, processes, and quality management system of testing and calibration laboratories. New requirements were established for organization of laboratory activities – the process based approach and risk-targeted thinking, which provides for the cutting of some part of the prescriptive requirements and introduction of requirements based upon analysis of actions performed. In accordance with GOST ISO/IEC 17025-2019, the laboratory is required to provide risk identification and assessment processes, develop risk control measures and expand opportunities to achieve the established purposes and objectives. The standard requires the laboratory to plan and perform actions to manage risks and opportunities associated with laboratory activities. This article deals with organization of the quality management system of Transneft system organizations’ laboratories in the aspects of risk management, management of opportunities, corrective actions with the use of laboratory information management system (LIMS). The model of the process implementation is described, subject to requirements of GOST ISO/IEC 17025-2019. Обновленная редакция стандарта ISO/IEC 17025 внесла существенные изменения в структуру, терминологию, требования к ресурсам, процессам, системе менеджмента качества испытательных и калибровочных лабораторий. Были установлены новые требования к организации деятельности лабораторий – процессный подход и риск-ориентированное мышление, что предусматривает сокращение части предписывающих требований и введение требований, основанных на анализе выполнения действий. В соответствии с ГОСТ ISO/IEC 17025-2019 от лаборатории требуется обеспечить процессы идентификации и оценки рисков, разработку мер по контролю рисков и расширению возможностей для достижения поставленных целей и задач. Стандарт требует от лаборатории планирования и реализации действий по управлению рисками и возможностями, связанными с лабораторной деятельностью. В настоящей статье рассматривается организация системы менеджмента качества лабораторий организаций системы «Транснефть» в части управления рисками, возможностями, корректирующими действиями с применением лабораторной информационной менеджмент-системы (ЛИМС). Описана модель реализации процесса с учетом соблюдения требований ГОСТ ISO/IEC 17025-2019.

Coordinate metrology techniques are widely used in industry to carry out dimensional measurements. For applications involving measurements in the submillimeter range, the use of optical, non-contact instruments with suitable traceability is usually advisable. One of the most used instruments to perform measurements of this type is the confocal microscope. In this paper, the authors present a complete calibration procedure for confocal microscopes designed to be implemented preferably in workshops or industrial environments rather than in research and development departments. Therefore, it has been designed to be as simple as possible. The procedure was designed without forgetting any of the key aspects that need to be taken into account and is based on classical reference material standards. These standards can be easily found in industrial dimensional laboratories and easily calibrated in accredited calibration laboratories. The procedure described in this paper can be easily adapted to calibrate other optical instruments (e.g., focus variation microscopes) that perform 3D dimensional measurements in the submillimeter range.
