| Description |
INTRODUCTION. Liquid penetrant testing (PT) is one of the most widely used non-destructive testing methods for detecting surface discontinuities in nonporous solid materials. This method has shown good results when looking for defects in details made of any nonporous materials including glass, ceramics, plastic, magnetic or nonmagnetic metals or alloys. Penetrant materials and check samples are the main tools for PT. The samples are used to estimate the performance of penetrant materials and to evaluate the sensitivity of the testing technology. AIM OF THE PAPER. The paper aims to evaluate the discontinuity parameters, such as cracks, in non-metal samples to determine the feasibility of using these samples to assess the sensitivity of the testing technology. METHODS. Discontinuity parameters in non-metallic check samples were determined using a microscope, and then the data was statistically processed in accordance with GOST 8.736-2011"Multiple direct measurements. Methods of measurement results processing. Main principles". RESULTS. The conducted study has showed that samples made of non-metallic material can be used to estimate the performance of penetrant families, as well as to assess penetrant testing sensitivity since the cracks in samples are virtually straight.
