The crack detection index (CDI) of the slit IQI has a good correlation with the crack probability of detection (POD) for a CrMoV welded joint (28 mm thick) with induced thermo-mechanical cracks. POD depends on film type (± 10% class<sup>−1</sup>) and film density (±50% for optical density variation between <em>D</em> = 1.5 – 3.5). The major influences of unsharpness and irradiation angle upon POD are also presented. The difference in sensitivity between X-rays and Ir-192 gamma rays can be explained by ‘energy-unsharpness’ factor variation with thickness. A correlation between slit IQI parameter (depth = width) and DIN (wire) IQI diameter was found. An experimental formula between CDI and total unsharpness (<em>u</em><sub>t</sub>) for X-rays and film density <em>D</em> = 2.5 – 3.0 was also found: <em>Fu</em><sub>t.</sub><em>CDI</em> = 2.1, where <em>F</em> = 0.87–1.0 is a film factor.</p><p>Proposals for codes of good practice, to obtain good ‘crack sensitivity’ based on the presented data, are given.</p></div>","PeriodicalId":100946,"journal":{"name":"NDT International","volume":"23 6","pages":"Pages 345-350"},"PeriodicalIF":0.0,"publicationDate":"1990-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0308-9126(90)90860-Q","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72079971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
