ASTM E802-95(2010)
(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
SIGNIFICANCE AND USE
These reference radiographs, along with the referenced applicable steel casting standards (Reference Radiographs E186 and E446), are supplied as a means of establishing categories and severity levels of common internal discontinuity types in gray iron castings subjected to radiographic examination. They may be used in accordance with contractual specifications as agreed upon between purchaser and supplier.
The use of this standard is not intended to be restricted to the specific energy level or to the absolute thickness limits that are contained in this standard title. The title is intended to be descriptive and not restrictive. This document may be used, where there is no other applicable document, for other energy levels or thicknesses, or both, for which it is found to be applicable and for which agreement has been reached between purchaser and supplier.
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.
Note 1—The reference radiograph films are an adjunct to this document and must be purchased separately from ASTM International if needed.
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.
