METROLOGICAL SUPPORT OF SPIROGRAPHY MEASURING DEVICES

Abstract

The need for spirographs which can secure reliability, safety, accuracy and metrological traceability has increased in recent years, due to growing number of chronic obstructive pulmonary diseases worldwide, especially in industrialized countries with high level of air pollution. The purpose of this study is to present findings from verification method developed on the basis of scientific fundamentals of the metrological support of a spirograph measuring device. The study has been conducted in accordance with international requirements for metrological characteristics of spirograph measuring devices and their accuracy. The findings reveal that the methodology for verifying the spirograph measuring device was approved and registered by the Uzbek Technical Regulatory Agency. This, in turn, serves to ensure reliability, safety, accuracy and metrological traceability of spirograph measuring devices.
