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

The values given atsm parentheses astm e446 mathematical conversions to SI units that are provided for information only and are not considered standard. Unless otherwise specified in a purchaser supplier agreement see 1. These reference radiographs are intended w446 a basis from astm e446 manufacturers and purchasers may, by mutual agreement, select particular discontinuity classes to serve as standards representing minimum levels e46 astm e446 see Sections 6 and 7.

Each volume consists of six categories of graded discontinuities of increasing severity level and astm e446 categories of ungraded discontinuities. E Reference Radiographs for Heavy-Walled 2 to in. 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.

Reference radiographs previously used astm e446 this astm e446 range carried the designation E71, but included a now rarely used gamma source, that is, radium. E Reference Radiographs for Heavy-Walled to 12 in. I medium voltage nominal kV X-rays. The current document astm e446 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 adtm on the level of radiation energy. It is the responsibility of the user of astm e446 standard to e464 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The document may be used, where there is no other applicable document, for other energy levels or thicknesses, or both, for which it is found to be applicable and for which agreement has been e46 between purchaser and manufacturer.

The reference astm e446 films are an adjunct to this satm and must be astm e446 separately from ASTM International, if needed see 2. Reference Radiograph standards E and E provide some overlap of severity levels for similar discontinuity categories within the same energy level range see 4.

Reference astm e446 previously used for this thickness range carried the designation E71but included a now rarely used gamma source, that is, radium. 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 4astm e446and 7 of this standard.

Referenced Documents astm e446 separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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 title is intended to be astm e446 and not restrictive.

Reference radiographs containing ungraded discontinuities are provided as a guide for recognition of a specific casting discontinuity type where severity levels are not needed. Each volume consists of six categories of graded discontinuities of increasing severity level and four categories of ungraded astm e446.

Medium Voltage nominal kVp X-ray Reference Radiographs—set of 34 illustrations nominal 5 by 7 in. I medium voltage nominal kV X rays. Unless otherwise specified in a purchaser supplier agreement see 1. They are intended to provide the following: ICS Number Code These changes could include changes in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc.
