Abstract Knowledge of the measurement uncertainty of test results is fundamentally important for laboratories, their customers and all parties using and interpreting these results. In conformity assessment, a measurement result is used to decide if an item of interest conforms to a specified requirement. Because of measurement uncertainty, there is always the risk of incorrectly deciding whether or not an item conforms to a specified requirement based on the measured value of a property of the item. Conformity assessment can be quite challenging when the entity measured is so close to the tolerance limits of the specification that its uncertainty, however estimated, critically affects decision-making. In such cases, different decision rules can be used to make statements of conformity. The aim of this paper is to provide a survey of methods for the evaluation of measurement uncertainty in testing, as well as to stress the need for appropriate estimation of measurement uncertainty. This paper also aims to assist testing laboratories in understanding the different decision rules used in conformity assessment and level of risk (such as false accept and false reject) associated with the decision rule employed.

Conformity assessment activities facilitate market acceptance for manufacturers, importers, exporters and traders by providing confidence that applicable requirements are being met. There is no trade without conformity assessment. There is no competitive market without standards. There is no free movement of goods without harmonisation of requirements and mutual recognition. This article presents state of the art of conformity assessment and tries to look for the future challenges of development of conformity assessment and accreditation. It is still the crucial point that market players develop a common understanding of the requirements that have to be fulfilled. On markets where free movement of goods and services is possible, another challenge is how to obtain the maximum benefits from harmonisation of standards and accredited conformity assessment activities.

With the declaration of independence of Ukraine, a new stage of the state has begun, accompanied by radical changes in all areas of public life. A person, his life and health, honor and dignity, integrity and security are determined by the highest social value. Therefore, the main duty of the state proclaims the assertion and protection of human rights and freedoms, for which a whole mechanism is created and functioning, each of which elements performs separate tasks in order to achieve a common goal. Forensic institutions are part of the relevant system and contribute to the establishment of objective truth in cases of violation of law, the rights and freedoms of participants in the process through an objective and fair trial or an objective basis for evaluating the results of pre-trial investigation bodies. In addition to performing these tasks, forensic institutions in Ukraine have a number of necessary conditions for carrying out conformity assessment activities, and therefore, with some transformations of the management system, technical and other improvements to meet the requirements of national standards, harmonized with relevant international and European standards in the field of assessment compliance, state specialized agencies can be accredited for compliance with the requirements of the standard ISO/IEC 17025 (as well as ISO/IEC 17020) and carry out conformity assessment activities in a specific industry. The article is devoted to the definition of administrative procedures for the accreditation of forensic institutions of Ukraine. Attention is focused on understanding the essence of administrative procedure and their place in the process of accreditation of conformity assessment bodies. The author analyzes the scientific approaches to considering the classification of the category “administrative procedure”. According to the results of the study, it can be stated that the administrative procedures for the accreditation of forensic institutions of Ukraine characterizes the procedure for authorized entities (national accreditation body of Ukraine) to carry out legally significant actions, the totality of which constitutes the legal process of accreditation; procedural requirements for these entities.
