摘要： 1.1This practice covers two procedures for ultrasonic testing (UT) of flat panel (parallel surfaces) composites and flat sandwich core panels. Typical as-fabricated lay-ups include uniaxial, cross ply, and angle ply laminates, as well as honeycomb sandwich core materials. These procedures can be used throughout the life cycle of the materials: product and process design optimization, on line process control, after manufacture inspection, and in-service inspection. Contact methods, such as angle-beam techniques using shear waves, are not discussed.1.2Ultrasonic testing is a common subsurface method for detection of laminar discontinuities. Two techniques can be considered based on panel surface accessibility; pulse echo for one sided and through transmission (bubblers/squirters) for two sided. As used in this practice, both require the use of a pulsed straight-beam ultrasonic longitudinal wave followed by observing indications of either the reflected (pulse-echo) or received (through transmission) wave. The general types of anomalies detected by both techniques include foreign materials, delamination, disbond/un-bond, fiber de-bonding, inclusions, porosity, and voids.1.3This practice provides two ultrasonic test procedures. These test procedures can be applied to small area manual scanning and large area automated scanning. Each has its own merits and requirements for inspection and shall be selected as agreed upon in a contractual document.1.3.1Test Procedure A, Pulse Echo (Non-contacting and Contacting),is at a minimum a single transducer transmitting and receiving a longitudinal wave in the range of 0.5 MHz to 20 MHz (seeFig. 1). This procedure requires access to only one side of the specimen. This procedure can be conducted by automated or manual means. Automated and manual test results may be imaged or recorded.FIG. 1Test Procedure A, Example Pulse Echo Apparatus Set-ups1.3.2Test Procedure B, Through Transmission,is a combination of two transducers. One transmits a longitudinal wave and the other receives the longitudinal wave in the range of 0.5 MHz to 20 MHz (seeFig. 2for an example set-up using squirters). This procedure requires access to both sides of the specimen. This procedure is automated and the examination results are recorded.FIG. 2Test Procedure B, Through Transmission Apparatus Set-up Using Squirters1.4This practice does not specify accept-reject criteria.1.5Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.6This 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.1.7This 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. ====== Significance And Use ======5.1This practice is intended primarily for the testing of flat panel composites and sandwich core panels to an acceptance criteria most typically specified in a purchase order or other contractual document.5.2Basis of Application—There are areas in this practice that require agreement between the cognizant engineering organization and the supplier, or specific direction from the cognizant engineering organization.

摘要： 1.1When an observer looks through an aerospace transparency, relative optical distortion results, specifically in thick, highly angled, multilayered plastic parts. Distortion occurs in all transparencies but is especially critical to aerospace applications such as combat and commercial aircraft windscreens, canopies, or cabin windows. This is especially true during operations such as takeoff, landing, and aerial refueling. It is critical to be able to quantify optical distortion for procurement activities.1.2This test method covers the apparatus and procedures that are suitable for measuring the grid line slope (GLS) of transparent parts, including those that are small or large, thin or thick, flat or curved, or already installed. This test method is not recommended for raw material.1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3.1Exception—The values given in parentheses are for information only.1.4This 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.1.5This 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. ====== Significance And Use ======5.1Transparent parts, such as aircraft windshields, canopies, cabin windows, and visors, shall be measured for compliance with optical distortion specifications using this test method. This test method is suitable for assessing optical distortion of transparent parts as it relates to the visual perception of distortion. It is not suitable for assessing distortion as it relates to pure angular deviation of light as it passes through the part. Either Test MethodF801or PracticeF733is appropriate and shall be used for this latter application. This test method is not recommended for raw material.

摘要： 1.1This practice is intended to be used as a supplement to PracticesE1742,E1255,E2033, andE2698.1.2This practice describes procedures for radiographic examination of flat panel composites and sandwich core materials made entirely or in part from fiber-reinforced polymer matrix composites. Radiographic examination is:a) Film Radiography (RT),b) Computed Radiography (CR) with Imaging Plate,c) Digital Radiography (DR) with Digital Detector Array’s (DDA), andd) Radioscopic (RTR) Real Time Radiography with a detection system such as an Image Intensifier. The composite materials under consideration typically contain continuous high modulus fibers (> 20 GPa), such as those listed in1.4.1.3This practice describes established radiographic examination methods that are currently used by industry that have demonstrated utility in quality assurance of flat panel composites and sandwich core materials during product process design and optimization, process control, after manufacture inspection, in service examination, and health monitoring. Additional guidance can be found inE2533, Guide for Nondestructive Testing of Polymer Matrix Composites Used in Aerospace.1.4This practice has utility for examination of flat panel composites and sandwich constructions containing, but not limited to, bismaleimide, epoxy, phenolic, poly(amide imide), polybenzimidazole, polyester (thermosetting and thermoplastic), poly(ether ether ketone), poly(ether imide), polyimide (thermosetting and thermoplastic), poly(phenylene sulfide), or polysulfone matrices; and alumina, aramid, boron, carbon, glass, quartz, or silicon carbide fibers. Typical as-fabricated geometries include uniaxial, cross ply and angle ply laminates; as well as honeycomb core sandwich constructions.1.5This practice does not specify accept-reject criteria and is not intended to be used as a means for approving flat panel composites or sandwich core materials for service.1.6To ensure proper use of the referenced standards, there are recognized nondestructive testing (NDT) specialists that are certified according to industry and company NDT specifications. It is recommended that a NDT specialist be a part of any composite component design, quality assurance, in service maintenance or damage examination.1.7This 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.1.8This 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. ====== Significance And Use ======5.1Radiographic examination may be used during product and process design optimization, on line process control, after manufacture inspection, and in service inspection. In addition to verifying structural placement, radiographic examination can be used in the case of honeycomb core materials to detect node bonds, core-to-core splices, and core-to-structure splices. Radiographic examination is especially well suited for detecting sub-surface flaws. The general types of defects detected by radiographic examination include blown core, core corrosion, damaged filaments, density variation, entrapped fluid, fiber debonding, fiber misalignment, foreign material, fractures, inclusions, micro-cracks, node bond failure, porosity/voids, and thickness variation.5.2Factors that influence image formation and X-ray attenuation in radiographic examination, and which are relevant to interpreting the images for the conditions of interest, should be included in the examination request. Examples include, but not limited to, the following: laminate (matrix and fiber) material, lay-up geometry, fiber volume fraction (flat panels); facing material, core material, facing stack sequence, core geometry (cell size); core density, facing void content, adhesive void content, and facing volume percent reinforcement (sandwich core materials); overall thickness, specimen alignment, and specimen geometry relative to the beam (flat panels and sandwich core materials).5.3Information regarding discontinuities that are detectable using radiographic examination methods can be found in GuideE2533.

摘要： 1.1The digital reference images provided in the adjunct to this standard illustrate various types and degrees of discontinuities occurring in thin-wall steel investment castings.2Use of this standard for the specification or grading of castings requires procurement of the adjunct digital reference images which illustrate the discontinuity types and severity levels. They are intended to provide the following:1.1.1A guide enabling recognition of thin-wall steel casting discontinuities and their differentiation both as to type and degree through digital radiographic examination.1.1.2Example digital radiographic illustrations of discontinuities and a nomenclature for reference in acceptance standards, specifications, and drawings.1.2Two illustration categories are covered as follows:1.2.1Graded—Six common discontinuity types each illustrated in eight degrees of progressively increasing severity.1.2.2Ungraded—Twelve single illustrations of additional discontinuity types and of patterns and imperfections not generally regarded as discontinuities.1.3The reference radiographs were developed for casting sections up to 1 in. (25.4 mm) in thickness.1.4All 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.Note 1:The set of digital reference images consists of 16 digital files, software to load the desired format, and specific instructions on the loading process. The 16 reference images illustrate eight grades of severity in six common discontinuity types and twelve ungraded discontinuities and contain an image of a step wedge and two duplex-wire gauges. Available from ASTM International Headquarters. Order number RRE2660. Refer to PracticeE2002for wire pair details.1.5Units—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.1.6These digital reference images are not intended to illustrate the types or degrees of discontinuities when performing film radiography. If performing film radiography of thin-wall investment castings, refer to Reference RadiographsE192.1.7Only 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.1.8This 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.1.9This 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. ====== Significance And Use ======4.1Personnel utilizing reference radiographs to this standard shall be qualified to perform radiographic interpretation in accordance with a nationally or internationally recognized NDT personnel qualification practice or standard and certified by the employer or certifying agency, as applicable. The practice or standard used and its applicable revision shall be identified in the contractual agreement between the using parties. If assistance is needed with interpreting specifications and product requirements as applied to the reference radiographs, a certified Level III shall be consulted before accept/reject decisions are made (if the Level III is the radiographic interpreter, this may be the same person).4.2These digital reference images are intended for reference only, but are designed such that acceptance standards, which may be developed for particular requirements, can be specified in terms of these digital reference images. The illustrations are digital images of castings that were produced under conditions designed to develop the discontinuities.4.2.1Graded Discontinuities:4.2.1.1Gas holes, sponge shrinkage, dendritic shrinkage, less dense foreign material(1)The images of the1/8-in (3.2-mm) castings are intended to be used in the thickness range up to and including1/4-in (6.3-mm).

For example, electrical interference, hardware incompatibilities, and corrupted files and drivers may affect their appearance. The PracticeE2002line pair gauges located in each digital reference image can be used as an aid to detect image deterioration by comparing the measured resolution using the gauges to the resolution stated on the digital reference image. Do not use the digital reference images if their appearance has been adversely affected such that the interpretation and use of the images could be influenced.4.4Agreement should be reached between cognizant engineering organization and the supplier that the system used by the supplier is capable of detecting and classifying the required discontinuities.
