Standard Reference Radiographs for Titanium Castings

1.1 These reference radiographs are reproductions of original radiographs and are supplied as a means for establishing some of the categories and severity levels of discontinuities in titanium castings that may be revealed by radiographic examination. The title is intended to be descriptive and not restrictive. The document may be used, where there is no other applicable document, for other energy levels, thicknesses, or both, for which agreement has been reached between purchaser and manufacturer. They should be used in accordance with contractual specifications.

Note 1--The original radiographs produced for Volume I were taken with x-rays in the range of 110 KV to 220 KV. The original radiographs produced for Volume II were taken with x-rays in the range of 200 K to 340 KV.

1.2 These reference radiographs consist of two volumes. Volume I, described in Table 1 , is applicable to a wall thickness of up to 1 in. (0 to 25.4 mm). Volume II, described in Table 2 , is applicable to a wall thickness of over 1 in. to 2 in. (25.4 mm to 50.8 mm).

1.3 The plates produced to serve for use in this standard were purposely cast to exhibit the desired discontinuity. The plates were cast using different processes as shown in Table 1 and Table 2 . Hot isostatic pressing was not used on any of the plates.

1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for informational purposes only.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
