(Specification)Standard Reference Radiographs for Gray Iron Castings Up to 4 1/2 in. (114 mm) in Thickness
Standard Reference Radiographs for Gray Iron Castings Up to 4 1/2 in. (114 mm) in Thickness
SCOPE
1.1 These reference radiographs for gray iron castings consist of one set of illustrations of centerline shrinkage with severity levels 1 to 5 using three radiation source types as follows:
1.1.1 Volume I: Medium Voltage (nominal 250 kVp) X-Ray Reference Radiographs -Set of 5 severity levels in a 15 by 17 in. folder.
1.1.2 Volume II: Iridium-192 Reference Radiographs Set of 5 severity levels in a 15 by 17 in. folder.
1.1.3 Volume III: Cobalt-60 Reference Radiographs -Set of 5 severity levels in a 15 by 17 in. folder.
1.2 The values stated in inch-pound units are to be regarded as the standard.
1.3 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.
