Fundamentals in Measurement: Basic Practical Elements of Quality Assessment of Calibration Laboratory Activities

Testing and calibration laboratories are important components of the national quality infrastructure. They ensure the accuracy, reliability and safety of production and quality control of various manufactured products. The primary purpose of testing laboratories is to test components or finished products to determine their compliance with international, regional, and national standards, technical regulations, or manufacturer specifications. The main purpose of calibration laboratories (CLs) is to calibrate measuring instruments and measurement standards in accordance with the requirements of standards and manufacturer specifications for testing laboratories and other end users. The joint activities of testing and calibration laboratories contribute to proving the quality and safety of the manufacturer's products not only in the national but also in the global markets.
