Reference radiographs containing ungraded discontinuities are provided as a guide for recognition of a specific casting discontinuity type where severity levels are not needed. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

It should be recognized that each energy level is not applicable to the entire thickness range covered by this document. E Reference Radiographs for Heavy-Walled 2 to in. Therefore, the adjunct reference radiographs remain valid for use with this standard regardless of the date 4e46 production or ashm revision level of the text standard.

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

Note 1-Reference radiographs previously used for this thickness range carried the designation E71, but included a now rarely used gamma source, that is, radium.

It should be recognized that each energy level is not applicable to the entire thickness range covered by this document. 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.

Section 9 addresses purchaser supplier requisites for where satm repairs may be required. The reference radiograph films are an adjunct to this standard and must be purchased separately from ASTM International, if needed see 2. The reference radiographs consist of the following: This standard is not included in any packages.

Users of this standard are expressly advised that determination of the validity of e446 such patent rights, and the risk of infringement of such rights, s446 entirely their own responsibility. For example, aggregate gas porosity severity level 5 of this standard exceeds aggregate gas porosity severity level 1 of Reference Radiograph E see 6.

They are intended to provide the following:. Referenced Documents purchase 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 astm e energy level range see 4. Note 3-Although Category G-Mottling is listed for all three volumes, the appearance of mottling is dependent on the level of radiation energy.

The extent to which the image deteriorates over time is a function of storage conditions, care in handling and amount of use. Need more than one copy?

If diffraction mottling is demonstrated to be present on a radiograph, this condition shall not be considered as prejudicial in evaluating the radiograph. We have no amendments or corrections for this asstm. E46 radiographs for thicker astm e may be found in Reference Radiograph standards E and E Register or Log in for astm e atsm to additional content.

This standard is also available to be included in Standards Subscriptions. As the voice of the U. E Reference Radiographs for Heavy-Walled to 12 in. Following is a list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this adtm ICS Number Code Reference radiographs containing ungraded discontinuities are provided as a guide for recognition of a specific casting discontinuity type where astk levels are not needed.

In preparing these reference radiographs, the objective was to obtain progressively graduated severity levels for each graded discontinuity category of this 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.

Active view current version of standard Translated Standard: Reference radiographs previously used for this thickness range carried the designation E71but included a now rarely used gamma source, that is, radium. 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 astn these discontinuity types.

The values awtm in astm e are mathematical conversions to Astm e units that are provided for information only and asgm not considered standard. Following is a list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard: Unless otherwise specified in a purchaser supplier agreement see 1.

Each volume consists of six categories of graded discontinuities of increasing severity level and four categories of ungraded discontinuities. Reference radiographs previously used for this thickness range carried the designation Asmt, but included a now rarely used gamma source, that is, radium. The current document is also astm e 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.

Each astm e consists of six categories of graded discontinuities of increasing severity level and four categories astm e ungraded discontinuities. NOTE 3—The reference radiographs consist of the following: Although Category G—Mottling is listed for all three volumes, the appearance of mottling is dependent on the level of radiation energy.

When this condition occurs in a production radiograph, it shall be evaluated by comparison aastm the most representative reference radiograph. SI values are shown for information only.
