General Concepts. Legal Basis of Metrology Metrology is the science of measurements, methods and means to ensure traceability and achieve required accuracy. Thus, metrology includes three interrelated problems: implementation of measurement processes, measurement traceability assurance, methods and means of measurement. The main tasks of metrology according to RMG are: establishment of physical units; establishment of state standards and reference measuring instruments; development of the theory, methods and means of measurement and inspection; development of methods for assessing errors and condition of the means of measurement and inspection; development of methods of transferring units from standards or refer- ence measurement means to the working measurements means. The legal framework of metrology includes the following general doc- uments: RF Law On ensuring the traceability of measurements; RMG State system for ensuring the traceability of measure- ments. Physical units; PR Verification of measurement tools. Organiza- tion and procedure of verification; PR Procedure of testing and approval of the measuring instruments type; PR Accreditation of metrological services of legal entities for the right for verification of measuring means; MI GSI. System of certification of measurements means. The fundamentals and procedures of the certification; PR

The main objective is to maintain uniformity of measurement in a particular country.

Thus, industrial inspection has become a very important aspect of quality control. Ascertain that the part, material, or component conforms to the established or desired standard. Accomplish interchangeability of manufacture. Sustain customer goodwill by ensuring that no defective product reaches the customers. Provide the means of finding out inadequacies in manufacture.

The results of inspection are recorded and reported to the manufacturing department for further action to ensure production of acceptable parts and reduction in scrap. Inspection 5.

download good-quality raw materials, tools, and equipment that govern the quality of the finished products. Coordinate the functions of quality control, production, downloading, and other departments of the organizations.

Promote the spirit of competition, which leads to the manufacture of quality products in bulk by eliminating bottlenecks and adopting better production techniques.

Accuracy and Precision. Measurand, a physical quantity such as length, weight, and angle to be measured.
