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 Sections 6 and 7.

Link to F446 This link will always route to the current Active version of the standard. Reference radiographs containing ungraded discontinuities are provided as a guide for recognition of a specific casting discontinuity type where severity levels are not needed. Historical Version s – view previous versions of standard. The e46 radiograph films are an adjunct to this standard and must be purchased separately from ASTM International, if needed see 2.

Following is a list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard: S446 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.

Referenced Documents purchase separately The documents listed below are referenced within the w446 standard but are not provided as part of the standard. If performing digital radiography of steel castings up to 2 in. 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.

Standard Reference Radiographs for Steel Castings Up to 2 in. [51 mm] in Thickness

Severity levels of similar discontinuity categories and energy level range of E reference radiographs may alternatively be used, as determined appropriate for the casting service application, if so agreed upon in the purchaser supplier agreement see Note 2 and 5.

These changes could include changes in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc. Each volume consists of six categories of graded discontinuities of increasing severity level and four categories of ungraded discontinuities.
