The current document is also updated by inclusion of several recognized shrinkage or C categories and by elimination of the crack and hot tear categories except for one example of each of these discontinuity types. Although Category G—Mottling is listed for all three volumes, the appearance of mottling is dependent on the level of radiation energy.

I medium voltage nominal kV X-rays. Active view current version of standard. SI values are shown for information only. The reference radiographs consist of the following: Reference radiographs previously used for this thickness range carried the designation E71but included a now rarely used gamma source, that is, radium. Following is a list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard:. Link to Active This link will always route to the current Active version of the standard.

Therefore, the adjunct reference radiographs remain valid for use with this standard regardless of the date of production or the revision level of the text standard. The reference radiograph films are an adjunct to this standard and must be purchased separately from ASTM International, if needed see 2.
