Особенности разработки стандартных образцов для контроля ультразвуковых дефектоскопов. Ч. 1. Общие принципы построения многоэлементных стандартных образцов

Abstract

The features of certified reference materials (CRM) applications during non-destructive testing (NDT) are considered. It is shown that these CRM are the products for which it is advisable to standardize the communication parameters showing the dependence of NDT instruments information signal from the defect model geometry and physical properties of test material. The absence of CRM to control the ultrasonic defectoscopes electroacoustic canal nonlinearity is found. There is a need to develop the general principles for creating a new group of CRM, for example, in the form of multielement solidstate design, containing the models of the same type. The application of such CRM allows to defect the poor quality ultrasonic defectoscopes.
