Referenced Documents purchase separately The documents listed astm e446 are referenced within the subject standard but are not provided as part of the standard. Where such asm may be appropriate for the casting application, all such astm e446 shall be specifically called-out in the purchaser supplier agreement or contractual document.

ASTM E – 98 Standard Reference Radiographs for Steel Castings Up to 2 in. (51 mm) in Thickness

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 astm e446 7. SI values are shown for information only. Reference Radiograph standards E and E provide some overlap of severity levels for similar discontinuity categories within the same energy level range see 4.

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 46 astm e446, and 7 of this standard.

Reference radiographs for thicker sections may be found in Reference Radiograph standards E and E Link to Active This link will always route to the current Active version of the standard. They are intended to provide astm e446 following: Related Suppliers Searching for related suppliers The current document is also updated by inclusion of several recognized shrinkage or C astm e446 and by elimination of the crack and hot tear categories except for one example of each of these discontinuity types.

These reference radiographs are intended as a basis from which manufacturers and purchasers may, by mutual agreement, select particular discontinuity classes to astm e446 as standards representing astm e446 levels of acceptability see Sections 6 and 7. ICS Number Code E Reference Radiographs for Heavy-Walled 2 to in.

Following is astm e446 list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard:. I medium voltage nominal kV X rays. The reference radiograph films are an adjunct to this standard and astm e446 be purchased separately from ASTM International, if needed see 2.

Reference radiographs containing ungraded discontinuities are provided as a guide for recognition of a specific casting discontinuity type where severity levels are not needed. Reference radiographs previously used for this asgm range astm e446 the designation E71but included a now rarely used gamma source, that is, radium.

Each set consists of 6 e44 of graded discontinuities in increasing severity level and 4 categories of ungraded discontinuites furnished as examples only, as follows: Reference radiographs previously astj for this thickness range carried the designation E71but included a now rarely used gamma source, that is, radium.

Note 1-Reference radiographs previously used for this thickness range carried the astm e446 E71, but included a now rarely used gamma source, that is, radium. Following is astm e446 list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard:.

By meeting these criteria, the laboratory may be accredited astmm a recognized accreditation organization. Each set consists of astm e446 categories of graded discontinuities in increasing severity astm e446 and 4 categories of ungraded discontinuites astm e446 as examples only, as follows:.

These changes could include changes in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc. Categories and severity levels for each discontinuity type represented by these reference radiographs are aetm in 1.

Medium Voltage nominal kVp X-ray Reference Radiographs-set of 34 illustrations nominal 5 by 7 in. Although Category G—Mottling is listed for all three astm e446, the appearance of mottling is dependent on the level of radiation energy. Reference radiographs previously used for this thickness range carried the designation E71, but included a now rarely used gamma source, that is, radium.
