Scope

4.1 These digital reference images are intended for reference only, but are designed such that acceptance standards, which may be developed for particular requirements, can be specified in terms of these digital reference images. The illustrations are digital images of castings that were produced under conditions designed to develop the discontinuities.

4.1.1 Applicability of Thickness Designations: 

4.1.1.1 The discontinuity types, illustrated thickness and applicable thickness range are summarized in Table 1 for the Volume I images and in Table 2 for the Volume II images.

4.2 Image Deterioration—Many conditions can affect the appearance and functionality of digital reference images. For example, electrical interference, hardware incompatibilities, and corrupted files and drivers may affect their appearance. The Practice E2002 line pair gauges located in each digital reference image can be used as an aid to detect image deterioration by comparing the measured resolution using the gauges to the resolution stated on the digital reference image. Do not use the digital reference images if their appearance has been adversely affected such that the interpretation and use of the images could be influenced.

4.3 Agreement should be reached between cognizant engineering organization and the supplier that the system used by the supplier is capable of detecting and classifying the required discontinuities.

1.1 The digital reference images provided in the adjuncts to this standard illustrate various types and degrees of discontinuities occurring in titanium castings.2 Use of this standard for the specification or grading of castings requires procurement of the appropriate adjunct digital reference images, which illustrate the discontinuity types and severity levels. They are intended to provide the following:

1.1.1 A guide enabling recognition of titanium casting discontinuities and their differentiation both as to type and degree through digital radiographic examination.

1.1.2 Example digital radiographic illustrations of discontinuities and a nomenclature for reference in acceptance standards, specifications and drawings.

1.2 The digital reference images consist of twenty-five digital files each illustrating eight grades of increasing severity. The Volume I files illustrate seven common discontinuity types representing casting sections up to 1 in. (25.4 mm). The Volume II files illustrate five discontinuity types representing casting sections over 1 in. (25.4 mm) to 2 in. (50.8 mm) in thickness.

1.3 All areas of this standard may be open to agreement between the cognizant engineering organization and the supplier, or specific direction from the cognizant engineering or......
