ASTM E94/E94M-22 使用工业射线照相胶片进行射线照相检验的标准指南

1.1 This guide2 covers satisfactory X-ray and gamma-ray radiographic examination as applied to industrial radiographic film recording. It includes statements about preferred practice without discussing the technical background which justifies the preference. A bibliography of several textbooks and standard documents of other societies is included for additional information on the subject. 1.2 This guide covers types of materials to be examined; radiographic examination techniques and production methods; radiographic film selection, processing, viewing, and storage; maintenance of inspection records; and a list of available reference radiograph documents. NOTE 1—Further information is contained in Guide E999, Practice E1025, Practice E1030/E1030M, and Practice E1032. 1.3 The use of digital radiography has expanded and follows many of the same general principles of film based radiography but with many important differences. The user is referred to standards for digital radiography [E2597, E2698, E2736, and E2737 for digital detector array (DDA) radiography and E2007, E2033, E2445/E2445M, and E2446 for computed radiography(CR)] if considering the use of digital radiography. 1.4 Interpretation and Acceptance Standards— Interpretation and acceptance standards are not covered by this guide, beyond listing the available reference radiograph documents for castings and welds. Designation of accept reject standards is recognized to be within the cognizance of product specifications and generally a matter of contractual agreement between producer and purchaser. 1.5 Safety Practices—Problems of personnel protection against X-rays and gamma-rays are not covered by this guide. For information on this important aspect of radiography, reference should be made to the current document of the National Committee on Radiation Protection and Measurement, Federal Register, U.S. Energy Research and Development Administration, National Bureau of Standards, and to state and local regulations, if such exist. For specific radiation safety information, refer to NIST Handbook ANSI 43.3, 21 CFR 1020.40, and 29 CFR 1910.1096 or state regulations for agreement states. 1.6 Units—The values stated in either SI units or inchpound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system should be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.7 If an NDT agency is used, the agency should be qualified in accordance with Specification E543. 1.8 Personnel Qualification—If specified in the contractual agreement, personnel performing examinations to this guide should be qualified in accordance with a nationally or internationally recognized NDT personnel qualification practice or standard and certified by the employer or certifying agency, as applicable. 1.9 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Digital Reference Images for Inspection of Aluminum and Magnesium Die Castings

ASTM E505-22 铝和镁压铸件检验用标准参考射线照片

1.1 These reference radiographs illustrate the categories and severity levels of discontinuities that may occur in aluminumalloy and magnesium-alloy die castings. They are intended to provide: 1.1.1 A guide enabling recognition of discontinuities and their differentiation both as to type and severity level through radiographic examination. 1.1.2 Example radiographic illustrations of discontinuities and a nomenclature for reference in acceptance standards, specifications, and drawings. NOTE 1—The set of reference radiographs consists of five 81⁄2 by 11-in. cardboard frames containing radiographs covering discontinuities in aluminum and magnesium alloy die castings. The first four frames each contain two sets of four graded levels of increasing severity, while the last frame contains two ungraded radiographs. The 5 frames are contained in a 101⁄2 by 111⁄2-in. ring binder. NOTE 2—Reference radiographs applicable to aluminum and magnesium castings up to 2 in. (50 mm) in thickness are contained in ASTM Reference Radiographs E155, for Inspection of Aluminum and Magnesium Castings, Volumes I and II. 1.2 Two kinds of illustration categories are covered as follows: 1.2.1 Graded—Three discontinuity categories for aluminum die castings and three discontinuity categories for magnesium die castings, each illustrated in four levels of progressively increasing severity. Category A discontinuities are illustrated for aluminum and magnesium die castings having thicknesses of 1⁄8 in. (3.2 mm) and 5⁄8 in. (15.9 mm); Category B discontinuities are illustrated for 1⁄8-in. thick aluminum and magnesium die castings; and Category C discontinuities are illustrated for 5⁄8-in. thick aluminum and magnesium die castings. 1.2.2 Ungraded—One illustration of one discontinuity for 0.20-in. (5.1-mm) thickness aluminum die casting; and one illustration of one discontinuity for 1⁄8-in. (3.2-mm) thickness magnesium die casting. 1.3 This document may be used for other materials, thicknesses, or with other energy levels for which it has been found to be applicable and agreement has been reached between the purchaser and manufacturer. 1.4 From time to time, there may be minor changes to the process for manufacturing of the reference radiograph adjunct materials. These changes could include changes in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc.; however, in all cases, these changes are reviewed by the Illustration Monitoring Subcommittee and all reference radiographs are reviewed against a fixed prototype image to ensure that there are no changes to the acceptance level represented by the reference radiographs. 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. 1.5 These film reference radiographs are not intended to illustrate the types and degrees of discontinuities found in aluminum and magnesium die castings when performing digital X-ray imaging. When performing digital X-ray imaging of these castings, refer to Digital Reference Images E2973. 1.6 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM E2868-22 厚度不超过2 in.（50.8 mm）的钢铸件的标准数字参考图像

1.1 These digital reference images illustrate various categories, types, and severity levels of discontinuities occurring in steel castings that have section thicknesses up to 2 in. (50.8 mm). The digital reference images are an adjunct to this standard and must be purchased separately from ASTM International, if needed (see 2.3). Categories and severity levels for each discontinuity type represented by these digital reference images are described in 1.2. NOTE 1—The basis of application for these reference images requires a prior purchaser supplier agreement of radiographic examination attributes and acceptance criteria as described in Sections 4, 6, and 7 of this standard. 1.2 These digital reference images consist of three separate volumes (see Note 2) as follows: (I) medium voltage (nominal 250-kV) X-rays, (II) 1-MV X-rays and Iridium-192 radiation, and (III) 2-MV to 4-MV X-rays and Cobalt-60 radiation. Unless otherwise specified in a purchaser supplier agreement (see 1.1), each volume is for comparison only with production digital images produced with radiation energy levels within the thickness range covered by this standard. Each volume consists of six categories of graded discontinuities of increasing severity level and four categories of ungraded discontinuities. Reference images containing ungraded discontinuities are provided as a guide for recognition of a specific casting discontinuity type where severity levels are not needed. The following is a list of discontinuity categories, types, and severity levels for the adjunct digital reference images of this standard: 1.2.1 Category A – Gas porosity; severity levels 1 through 5. 1.2.2 Category B – Sand and slag inclusions; severity levels 1 through 5. 1.2.3 Category C – Shrinkage; 4 types: 1.2.3.1 Ca–linear shrinkage– Severity levels 1 through 5. 1.2.3.2 Cb–feathery shrinkage– Severity levels 1 through 5. 1.2.3.3 Cc–sponge shrinkage– Severity levels 1 through 5. 1.2.3.4 Cd–combinations of linear, feathery, and sponge shrinkage – Severity levels 1 through 5. 1.2.4 Category D–Crack; 1 illustration. 1.2.5 Category E–Hot Tear; 1 illustration. 1.2.6 Category F–Insert; 1 illustration. 1.2.7 Category G–Mottling; 1 illustration. (See Note 3.) NOTE 2—The digital reference images consist of the following: Volume I: Medium Voltage (nominal 250-kVp) X-Ray Reference Images – Set of 34 illustrations. Volume II: 1-MV X-Rays and Iridium-192 Reference Images – Set of 34 illustrations. Volume III: 2-MV to 4-MV X-Rays and Cobalt-60 Reference Images – Set of 34 illustrations. NOTE 3—Although Category G – Mottling is listed for all three volumes, the appearance of mottling is dependent on the level of radiation energy. Mottling appears reasonably prominent in Volume I; however, because of the higher radiation energy levels mottling may not be apparent in Volume II nor Volume III. 1.3 All areas of this standard may be open to agreement between the cognizant engineering organization and the supplier, or specific direction from the cognizant engineering organization. These items should be addressed in the purchase order or the contract. 1.4 These digital reference images are not intended to illustrate the types and degrees of discontinuities found in steel castings up to 2 in. (50.8 mm) in thickness when performing film radiography. If performing film radiography of steel castings up to 2 in. (50.8 mm) in thickness, refer to Reference Radiographs E446. 1.5 Only licensed copies of the software and images shall be utilized for production inspection. A copy of the ASTM/User license agreement shall be kept on file for audit purposes. (See Note 4.) NOTE 4—Each volume of digital reference images consists of 7 digital data files, software to load the desired format and specific instructions on the loading process. The 34 reference images in each volume illustrate six categories of graded discontinuities and four categories of ungraded discontinuities and contain an image of a step wedge. Available from ASTM International Headquarters, Order No: RRE286801 for Volume I, RRE286802 for Volume II, and RRE286803 for Volume III. 1.6 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1 These digital reference images are under the jurisdiction of ASTM Committee E07 on Nondestructive Testing and are the direct responsibility of Subcommittee E07.02 on Reference Radiological Images.

ASTM A898/A898M-17(2022) 轧制钢结构型材的直波束超声检验标准规范

1.1 This specification covers the procedure and acceptance standards for straight beam, pulse echo, ultrasonic examination of rolled structural shapes having a minimum section thickness of 1⁄2 in. [12.5 mm]. It was developed to ensure delivery of steel structural shapes free of gross internal discontinuities such as pipe, ruptures, or laminations and is to be used whenever the inquiry, contract, order, or specification states that the shapes are to be ultrasonically examined. Two levels of acceptance standards are included. Level II is intended for normal applications where freedom from gross internal discontinuities is desired, particularly in connection regions. Level I is intended for critical applications such as welded chord members used in tension loading, where internal discontinuities could be detrimental. Level II is normally applicable unless otherwise specified in contract documents or the purchase order. Supplementary requirements for alternative scanning coverages are provided. 1.2 The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
