  Summary of Major Changes in ASNT Recommended Practice SNT TC 1A 2024 edition Recently ASNT has released 2024 edition of SNT TC 1A - Personnel Qualification and Certification in Nondestructive testing .  Following are the summary of major changes when compared to previous editions 2020. Paragraph 1.5 was removed. Paragraphs 2.1.7 and 2.1.11 were updated to better define the terms “Detection Rate” and “False Call” to ensure their precise application. Paragraphs 2.1.15 and 2.1.18 were revised to further elucidate the term “Predictive Maintenance”. Additionally, to contrast with the term “NDT”, the definition of “ Non-Destructive Testing ” was included in accordance with ASTM E1316. The text in parentheses in paragraph 2.1.21 was amended to read: “This is usually done before any NDT is performed when there are concerns regarding the performance of the NDT or the instrument’s response.” In Table 6.3.1B, interpretations for digital radiography (RD), computed radiography (CR ), a...
