Abstract
This article outlines regulatory legal acts, standards and the application of measurement procedures. The description of the norm of characteristic indicators (requirements) for each product, be it bread, milk, petroleum products, light or heavy industry products, etc. is regulated in technical regulations, and further in regulatory documents for products, where for each indicator there are usually references to test methods of this product characteristic. For testing products, a test method is always necessary. In most cases, standard methods of testing and measurements have already been developed for these purposes, which are described in domestic or interstate standards: ST RK or GOST, as well as in international IEC, ISO, etc. However, there are no standard methods for testing in some cases. The solution to the problem in this case is the development of its own measurement methodology, the so-called non-standardized methodology, where measurement errors, subject to compliance with all the requirements of the document, are guaranteed. The article describes the stages of development, certification, approval and application of both conventional methods and reference measurement procedures. The article contains references from the legislation of the Republic of Kazakhstan in the field of ensuring the unity of measurements to standards, regulatory legal acts and the Law «On ensuring the unity of measurements».
