The aim of the task was to exercise metrological supervision over measurement equipment used in tests and calibration done in the Instituteʼs laboratories. The task was carried out in accordance with the requirements of the PN-EN ISO/IEC 17025:2005 standard "General requirements for the competence of testing and calibration laboratories", which is the basis for the quality management systems in force in CIOP-PIBʼs laboratories. This aim was achieved through: - metrological supervision over measurement equipment in the testing and calibration laboratories of the Institute, - updating the procedures and instructions related to calibrating testing and measuring equipment. 1009 items of measuring and testing equipment were periodically calibrated and/or checked; they are used in the Institute in laboratory tests in conformity assessment of products and in tests related to modelling working conditions. To improve the process of measuring and estimating their uncertainty, calibration methods of 15 types of elements of measuring and testing equipment were modified. At the same time methods of determining the uncertainty of measurements were updated in accordance with the requirements of the European Co-operation for Accreditation published in publication EA-4/02 "Expression of uncertainty of measurement in calibration". These tasks were connected with making the system of instructions and procedures in the Institute uniform.
