ASTM E390-11 PDF

1.1 This standard provides reference radiographs for steel fusion welds that contain typical discontinuities with varying severity levels in different thicknesses of material. The reference radiograph films are an adjunct to this standard and must be purchased separately from ASTM International if needed.

1.2 There are three volumes of reference radiographs based on seven nominal weld thicknesses as follows:

Vol I-Set of 16 plates (8¹/₂ by 11 in.) covering base material up to and including ¼ in. (6.4 mm) in thickness.

Vol II-Set of 29 plates (8½ by 11 in.) covering base material over ¼ to and including 3 in. (6.4 to 76 mm) in thickness.

Vol III-Set of 32 plates (8 ½ by 11 in.) covering base material over 3 to including 8 in. (76 to 203 mm) in thickness.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 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.
