These reference radiographs are intended as a basis from which manufacturers and purchasers may, by mutual agreement, select particular discontinuity classes to serve as standards representing minimum levels of acceptability see Asmt 6 and 7.

Reference radiographs for thicker sections may be found in Reference Radiograph standards E and E Reference Radiograph standards E and E provide some overlap of severity levels for similar discontinuity categories within the same energy level range see 4.

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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.

The basis of application for these reference radiographs requires a prior purchaser supplier agreement of radiographic examination attributes and classification criterion as described in Sections 46and 7 of this standard. The reference radiographs consist of the following: Each volume consists of six categories of graded discontinuities of increasing severity level and four categories of ungraded discontinuities.
